Atrial fibrillation, or AFib, is a condition in which the heart’s upper chambers beat irregularly, often causing a rapid heartbeat. Some people with AFib also experience chest discomfort, shortness of breath or heart palpitations. Others may notice only mild fatigue during activity. And still others may feel no symptoms at all. AFib also increases the risk of stroke.

“That’s why it’s especially important to carefully manage AFib in the summer, when people may spend more time in the sun, lose fluids through sweating, and drink more alcohol on vacation, at barbecues and at other outdoor social gatherings,” said Archana Ramireddy, MD, a clinical electrophysiologist in the Smidt Heart Institute. “Older adults are especially affected by the heat, even if it may not seem obvious at first.”

In recognition of AFib Awareness Month in September—when Southern California often experiences some of its hottest weather—the Cedars-Sinai Newsroom spoke with Ramireddy about steps people with AFib can take to stay healthy.

What summer factors can trigger an AFib episode?

Hot weather can put added stress on the heart, but heat itself isn’t necessarily the primary concern. Dehydration is of special concern because people lose fluids through sweating. Older adults may be particularly susceptible to heat-related dehydration because the body’s ability to conserve fluids and regulate temperature can decline with age. Alcohol is another concern because it is a well-recognized trigger for AFib, and people tend to drink more during the summer while vacationing, spending time outdoors and attending social gatherings.

Should people with AFib drink plain water to stay hydrated, or do they need electrolytes?

Plain water is usually the best choice. Electrolyte drinks may be helpful in some circumstances, although individual needs vary based on heat exposure, activity level, how much a person has been sweating, and underlying health conditions.

What are the signs of dehydration?

Signs of dehydration can include dark urine, dizziness, dry mouth, fatigue, confusion and a rapid heartbeat. If symptoms are prolonged or severe, or if a person also is experiencing chest discomfort or shortness of breath, they should seek medical attention.

Is coffee off-limits for people with AFib?

One cup of coffee a day generally isn’t a concern. Even two cups may be acceptable, although for some patients I recommend switching extra servings to decaf or half-caf. It’s most important that people pay attention to their own bodies. If caffeine consistently triggers symptoms, cutting back is recommended. I’m far more concerned about the consumption of multiple energy drinks, because high doses of caffeine and other ingredients in these drinks can increase the risk of arrhythmias.

Is it safe for people with AFib to exercise in the summer?

I encourage regular exercise for my patients with AFib. If physical activity consistently triggers episodes, the underlying AFib should be evaluated and treated rather than simply avoiding exercise. That said, it’s best to avoid strenuous exercise during the hottest part of the day and to stay well-hydrated if outside in the heat. To combat overheating, seek air conditioning, drink plenty of water, take a cool shower or use cool towels.

What if a person thinks they may have AFib?

If a person has heart palpitations and isn’t sure what is causing them, capturing an episode can be key for diagnosis and treatment. This is where wearable devices, such as smartwatches, can play a role. If a device can record an ECG, or electrocardiogram, during an episode, a physician can review the tracing to determine whether it is consistent with AFib. Wearable devices have helped us identify more patients sooner, allowing us to begin treatment sooner. Preventing stroke is a major goal of AFib treatment. People who have been diagnosed with AFib should work with their healthcare team to determine whether further evaluation by a cardiac electrophysiologist is appropriate.

The multi-institutional study offers one of the clearest pictures of what happens during the earliest stages of disease. The findings could help researchers develop new ways to detect and prevent heart disease before plaque builds up inside arteries.

“We analyzed proteins and gene activity in coronary artery tissue from young adults who died of trauma and had no known coronary artery disease, and we found that more than half already had preclinical atherosclerosis,” said study first author Sarah Parker, PhD, an associate professor of Cardiology and Biomedical Sciences and co-director of the Proteomics and Metabolomics Core at Cedars-Sinai Health Sciences University. “This suggests that changes in cellular metabolism and communication begin before the inflammation long considered a hallmark of the disease.”

Published in the European Heart Journal, the study findings point to previously unrecognized molecular pathways—and a potential “master regulator” called MLXIPL—that could become targets for therapies aimed at preventing plaque from developing.

The Cedars-Sinai Newsroom spoke with Parker about the findings and how proteomics—the study of proteins—is helping researchers rethink the earliest stages of heart disease.

Why are proteins so important in understanding heart disease?

Proteins are the molecules that make cells function. They tell us how the body’s cells are responding to risk factors like cholesterol, blood pressure or smoking. Two people can have identical cholesterol levels, yet only one develops plaque. Proteins may help explain why. They provide a much more direct picture of what's happening inside the artery wall and may reveal why some people are more vulnerable to heart disease than others.

What did this most recent study reveal about the earliest stages of atherosclerosis?

Previous studies had shown that the earliest artery lesions can appear in the first decade of life. What we haven’t understood is what causes those early changes to progress into dangerous plaques that lead to heart attacks. In studying coronary artery tissue before people ever developed symptoms, we were able to capture some of the earliest molecular changes that appear to set the disease in motion. One of the biggest surprises was that we saw changes in cellular metabolism and communication before we saw the classic inflammatory signals traditionally associated with atherosclerosis.

To be clear, inflammation remains a defining feature of advanced atherosclerosis. What our study suggests is that important molecular changes begin much earlier. If we want to prevent plaque from forming, we need to understand those earliest changes—not just what happens after inflammation has already taken hold.

Explain MLXIPL, the potential ‘master regulator’ you identified.

We performed a master regulator analysis to identify the genes that may be coordinating these early events. Some of the regulators we found were exactly what we expected. But one stood out. MLXIPL is a transcription factor gene involved in cellular metabolism. Previous genetic studies have linked it to coronary artery disease through its role in the liver. Our findings suggest it may also play an important role directly within the artery wall. When we altered MLXIPL activity in lab-grown human artery tissue, we saw the protein changes we predicted. That makes it an exciting candidate for future therapies that interrupt disease before plaque develops.

How could these findings change atherosclerosis prevention?

Today, we estimate cardiovascular risk using factors such as high cholesterol, diabetes, smoking, age and family history. By the time plaque is visible on imaging, disease often is well underway. We hope to identify protein biomarkers in the blood that reveal what’s happening inside the artery wall much earlier. One day, a simple blood test could identify people who would benefit from preventive treatment before symptoms develop.

That said, our findings do not change current prevention recommendations. Managing cholesterol, blood pressure, diabetes, smoking, exercise and diet remain essential.

This study relied on a decades-long collaboration. Why was that essential?

This is a collaboration more than 20 years in the making. The project was spearheaded by proteomics pioneer Jennifer Van Eyk. (Van Eyk, PhD, is director of the Advanced Clinical Biosystems Research Institute in the Smidt Heart Institute at Cedars-Sinai and co-director of the Proteomics and Metabolomics Core.)

Our collaborators included investigators from many other institutions across the country. What began as a small group has grown into an ecosystem of investigators, trainees and collaborators. This kind of large-scale molecular study simply isn’t possible without that level of long-term partnership and shared expertise.

The designation from the condition’s oldest patient organization is awarded to programs with the infrastructure and experience needed to provide high-quality care to people with pulmonary hypertension, a type of high blood pressure that occurs in arteries of the lungs.

Pulmonary hypertension can make it difficult for blood to circulate through the lungs, forcing the heart to work harder. In severe cases, the condition can lead to heart failure. People with pulmonary hypertension often need care from several specialists.

The Cedars-Sinai Pulmonary Hypertension Clinic includes six physicians and one nurse practitioner. The pulmonary hypertension program combines cardiology and pulmonology, which allows patients to access multidisciplinary care from experts in the disease. Providers care for more than 250 patients each year and address multiple aspects of the disease, including diagnosis, medication management, symptom control and disease progression.

“At Cedars-Sinai, pulmonary hypertension specialists collaborate with colleagues in rheumatology, congenital heart disease, critical care medicine, lung transplantation and other specialties to create treatment plans tailored to patients,” said Yuri Matusov, MD, assistant professor of Medicine at Cedars-Sinai. “We are proud to care for an extraordinarily diverse patient population, some of whom come from very far away for their care.”

The association noted several outstanding aspects of the Cedars-Sinai Pulmonary Hypertension Clinic including:

• A team that collaborates and provides timely evaluation and management of people who are hospitalized and continues to provide consistent care when they leave the hospital.
• Monthly conferences with specialists in the Southern California region that allow for the review of complex pulmonary hypertension cases, knowledge-sharing and regional care coordination.
• For people with advanced disease, access to top-notch heart, lung and thoracic transplant programs.
• A research program led by doctors investigating potential treatments.

“We are honored for our clinic to have received this designation, the highest recognition available to pulmonary hypertension programs in the United States,” said Dael Geft, MD, assistant professor of Cardiology in the Smidt Heart Institute at Cedars-Sinai. “Ultimately, the greatest reward is helping our patients live longer, healthier and more fulfilling lives.”

Gilliam, 32, suffered sudden cardiac arrest, an electrical malfunction of the heart that causes it to abruptly stop beating. The odds were stacked against him: Sudden cardiac arrest kills about 90% of those who experience it outside of a hospital. Survival depended on a chain of people acting within minutes.

A fellow dancer immediately started CPR. Other dancers ran out of the dance studio in search of an automated external defibrillator (AED) and found one at a nearby dentist’s office. A speech pathologist who had just completed CPR recertification and happened to be nearby used the AED to revive Gilliam’s heartbeat.

Paramedics then rushed Gilliam to the Cedars-Sinai Emergency Department, where he had another cardiac arrest. Surgeons placed Gilliam on extracorporeal membrane oxygenation (ECMO), a form of advanced life support that temporarily took over the work of his heart, giving it time to recover—or, if necessary, bridging him to a transplant.

Cedars-Sinai experts say Gilliam’s case illustrates the importance of bystander CPR and quick medical response.

“The key to G’bari surviving sudden cardiac arrest was the fast-acting individuals who provided CPR, facilitated the use of an AED, and the Cedars-Sinai Emergency Department and cardiothoracic surgery teams who began ECMO within the hospital,” said Evan Kransdorf, MD, PhD, assistant professor of Cardiology in the Smidt Heart Institute and one member of Gilliam’s team of physicians and surgeons.

During cardiac arrest, blood stops circulating, explained Pedro Catarino, MD, a cardiothoracic surgeon in the Smidt Heart Institute at Cedars-Sinai.

“The cells of the body, particularly the brain, will die within a few minutes without circulation,” Catarino said. “Gilliam’s heart was in and out of a rhythm that doesn’t sustain circulation, so the surgery team put him on emergency life support.”

Gilliam’s heart had ceased working, so he was listed in the organ donation system. After 12 days on life support, Gilliam received the news every transplant candidate hopes for: A donor heart had become available.

“Heart transplantation offers a new chance at life for patients like Gilliam,” Catarino said. “Gilliam is an athlete and can look forward to going back to his career with a heart that has a long lifespan.”

A pathology report showed Gilliam had a severe form of hypertrophic cardiomyopathy, an inherited condition that causes the heart muscle to thicken so that the heart cannot contract and pump blood properly. The condition likely caused Gilliam’s sudden cardiac arrest, his medical experts say.

“Many people with hypertrophic cardiomyopathy don’t have symptoms, and athletes who are used to pushing themselves to be out of breath might not realize they have it,” Kransdorf said.

Geneticists in the Smidt Heart Institute tested samples of Gilliam’s heart and found that he had a genetic variant associated with hypertrophic cardiomyopathy. Experts encourage anyone with a family history to be screened for the condition, which affects about 1 in 500 people. Gilliam’s close family members are undergoing genetic testing.

Gilliam, whose credits include performing with Bad Bunny and on Jimmy Kimmel Live!, is now in physical therapy and preparing to return to dance.

“With dancing, it feels like I'm able to be my most authentic self and be the most vulnerable version of myself. It makes me feel alive,” he said.

Prior to his medical emergency, Gilliam’s schedule consisted of dance classes and gym training five days a week. He hopes to return to intense days and to continue teaching dance to elementary school students and choreographing dancers on TV and film sets. His mother and girlfriend are supporting him, as are many friends, family members and fellow dancers.

“What I learned from this experience is everyone should be trained in CPR because you never know what's going to happen,” Gilliam said. “Even more so, be a person of service. If you have the opportunity to help someone, do it.”

A new study led by Karlstaedt and published in Circulation reports that a specific enzyme plays an important role in keeping the heart beating. The discovery could help scientists create drugs that mimic the enzyme’s role and help people with heart failure, a condition in which the heart becomes too weak to pump blood properly.  

Karlstaedt, assistant professor of Cardiology in the Smidt Heart Institute at Cedars-Sinai, has spent more than a decade studying heart metabolism—the chemical process that powers the heart. She spoke with the Cedars-Sinai Newsroom about her dedication to uncovering treatments for the millions diagnosed with heart failure every year.

How is the heart’s metabolism different from the metabolism of other parts of the body?

There are thousands of tiny molecules called metabolites—including amino acids, glucose and fatty acids—that act as an energy source to help cells function properly. The heart is the only organ that can use almost any metabolite.

The heart is also unique because it never stops beating. It's not like other muscles, which can rest. Fueling heart cells requires fine-tuned, organized chemical reactions. The system functions perfectly until something disrupts it, and metabolism is at its center. 

What was one of the major discoveries that led to your current work? 

My colleagues and I published a study in 2016 in which we discovered that the heart uses unusual fuel-processing routes to adapt to metabolites released by cancer cells. It’s like in a city where you have streets and traffic moves along those streets. If a construction site suddenly blocks a street, traffic finds another way around. The heart does the same thing.

We also found that in response to cancer-related metabolic stress, the heart suddenly started using an unusual enzyme called ATP-dependent citrate lyase, or ACL. This enzyme drives the process that creates fatty acids, something we didn’t think happened in heart cells. But when we blocked ACL, the heart could not pump well. That told us this enzyme might be much more important for the heart than previously thought.

Could you describe your recent discovery?

We found that when ACL slows down, heart function drops. To make this discovery, we studied heart tissue samples from people with healthy hearts and people with failing hearts. We also observed ACL in the hearts of laboratory mice. When ACL activity decreased, meaning it no longer efficiently produced fatty acids, the heart tried to adapt by taking up more sugar and rewiring parts of its metabolism. But those changes did not fully protect the heart. Instead, the heart had less available energy and did not pump as well.

To dig deeper, we used CardioNet, our computational model of heart metabolism. The model pinpointed another enzyme, IDH1, that compensates for the loss of ACL. When we reduced IDH1 in our model, the heart could pump better. We're now studying whether future heart failure therapies could target IDH1.

What do you hope to accomplish as this work progresses?

Heart failure can look similar from one patient to another, but the underlying metabolic changes may be different. We hope to use our computational model to predict which fuel pathways are disrupted in people with heart failure and which treatments can get the heart working better. We are not there yet, but this study is an important step toward understanding heart failure as a disease of both mechanics and metabolism.

“The majority of people who have a sudden cardiac arrest outside of a hospital will die, so the best protection is being aware of risk,” said Kyndaron Reinier, PhD, MPH, associate director of Epidemiology in the Center for Cardiac Arrest Prevention in the Smidt Heart Institute at Cedars-Sinai and an author of both studies. 

Sudden cardiac arrest happens when a problem with the heart’s electrical system causes the heart to stop beating. It is different from a heart attack, which is caused by a lack of blood flow to the heart. More than 350,000 people experience sudden cardiac arrest outside of a hospital in the U.S. each year, and only about 10% survive. 

Experts know that people with low left ventricular ejection fraction, when the heart’s main pumping chamber is weak and pumps less than it should, are at higher risk for sudden cardiac arrest. But this marker has become less effective and other indicators are needed to capture more people at risk.

“More than two-thirds of people who have cardiac arrest don’t have low left ventricular ejection fraction, so using this marker alone misses too many people,” Reinier said. 

A study published in the journal Circulation: Arrhythmia and Electrophysiology reports that warning symptoms combined with clinical history could predict imminent sudden cardiac arrest. A second study, published in the Journal of the American Heart Association (JAHA), reports that having more than one cardiac event over time could signal rising risk. 

Reading Warning Symptoms

In the Circulation: Arrhythmia and Electrophysiology study, investigators used machine learning to identify combinations of symptoms and medical history that best predicted sudden cardiac arrest in the near future. 

The study included people enrolled in two separate, longstanding studies in Oregon and Ventura County, California, that were founded by Sumeet Chugh, MD, director of the Center for Cardiac Arrest Prevention in the Smidt Heart Institute. The investigators compared 364 people who called 911 when experiencing symptoms such as chest pain and survived sudden cardiac arrest, with 313 people who called 911 for similar symptoms but did not experience sudden cardiac arrest. 

The analysis found that people with sudden cardiac arrest were more likely to have a combination of shortness of breath and diagnosed coronary artery disease or heart failure than people who did not experience sudden cardiac arrest. Seizure-like symptoms without chest pain or shortness of breath were also more common in people who experienced sudden cardiac arrest.

The investigators also found that chest pain combined with coronary artery disease predicted imminent arrest in women, while chest pain combined with heart failure predicted it in men. 

Warning symptoms most often occurred at least 15 minutes prior to the sudden cardiac arrest, a time frame that would make it possible to call 911. In earlier research, the investigators found that 81% of people delayed their 911 call, reducing their chances of successful revival by ambulance paramedics. 

These findings could be used to create risk-predicting algorithms for use by urgent care and emergency medicine providers, the investigators said. “While more research is needed, such risk prediction algorithms have the potential to avoid 911 call delays following warning symptoms of sudden cardiac arrest,” said Chugh, vice dean and chief AI health research officer at Cedars-Sinai.

Tracking Risk Over Time

The JAHA study was carried out in the Observational Study of Cardiac Arrest Risk (O.S.C.A.R.) cohort at Cedars-Sinai, established by Chugh, that has been tracking the health of approximately 400,000 residents of Los Angeles County from 2017 onward. Of these, the investigators followed more than 6,700 people hospitalized at Cedars-Sinai for heart failure and more than 2,900 people hospitalized in the health system for acute coronary syndrome, when an artery blockage reduces blood flow to the heart. 

Investigators found that patients in both groups who experienced a recurrent cardiovascular event faced a higher risk of sudden cardiac arrest. 

Patients who had a second coronary artery blockage were more than three times as likely to experience sudden cardiac arrest as those without a recurrence. Patients who were hospitalized a second time for heart failure were nearly twice as likely to experience sudden cardiac arrest. Risk climbed with each additional heart failure hospitalization. The investigators compared the findings to what was found in participants of the Framingham Heart Study, which enrolled participants about 50 years earlier. The results were similar, however the heart failure result in that study did not reach statistical significance.

Reinier said that physicians should consider sudden cardiac arrest as being more likely when a patient is hospitalized for a heart issue a second time.

“This may mean running additional tests,” Reinier said. “It may mean educating the patient about what cardiac arrest is and the importance of having a family member who knows to call 911 and start CPR immediately if their loved one collapses.”

Moving Beyond Dead Ends

Chugh, senior author of both studies, said the combined findings point toward a more flexible approach to prediction.

“Near-term and long-term predictions are parallel approaches that can help us move past roadblocks we face in preventing death from this lethal heart event,” Chugh said.

Additional research, including studies in different populations, are needed to confirm whether the factors the investigators studied could be used in prediction tools, study authors said. 

Cedars-Sinai investigators continue to study predictors of sudden cardiac arrest, and their work includes using AI to study patterns in heart tests called electrocardiograms and looking for genetic causes.

Shehata is a cardiac electrophysiologist, a doctor who specializes in diagnosing and treating problems with the heart’s electrical system. He has experience with a broad spectrum of heart rhythm disorders and also cares for people with heart failure and survivors of cardiac arrest.

“Over the past two decades, Dr. Shehata has emerged as a nationally recognized cardiac electrophysiologist and academic leader,” said Susan Cheng, MD, MMSc, MPH, chair of the Department of Cardiology in the Smidt Heart Institute. “His leadership will mean continued progress in this important field.”

As a researcher, Shehata has led groundbreaking clinical trials for new types of pacemakers and other technologies for treating heart rhythm disorders. He also studies ways that AI can be used to personalize care.

Shehata’s most recent research includes a trial of a new treatment for atrial fibrillation, which occurs when the upper chambers of the heart beat out of sync with the lower chambers of the heart. The treatment, pulsed field ablation, targets heart cells involved in an abnormal heart rhythm. The U.S. Food and Drug Administration approved several pulsed field ablation systems, including one studied by Shehata and other researchers, in 2024.

Shehata and colleagues have also studied leadless pacemakers, miniature devices that attach to the heart muscle and that, unlike traditional pacemakers, don’t require a battery and wires.

As division director, Shehata will oversee a program that provides research-backed care and trains new heart rhythm specialists. The program offers a two-year fellowship to medical school graduates seeking advanced knowledge and skills in electrophysiology.

“Through his leadership of the Interventional Electrophysiology Laboratory and the Clinical Cardiac Electrophysiology Fellowship Program, Dr. Shehata has expanded access to advanced therapies and enhanced the training of future electrophysiologists,” said Eduardo Marbán, MD, PhD, executive director of the Smidt Heart Institute and the Mark S. Siegel Family Foundation Distinguished Professor.

Shehata earned his medical degree from the University of California, San Diego, School of Medicine. He completed internal medicine residency training at UCLA and his cardiology fellowship training at Cedars-Sinai, where he was chief fellow. He also completed advanced fellowship training in cardiac electrophysiology at Cedars-Sinai. He served as faculty at UCLA before being recruited to join the cardiology faculty at Cedars-Sinai, where he is a professor of Cardiology.

U.S. News & World Report rates the Smidt Heart Institute a top 10 cardiovascular center in the U.S. and #1 in California.

Fires can leave behind more than visible damage. The lingering smoke and airborne contaminants from the recent warehouse fire in the Boyle Heights neighborhood in Los Angeles may continue to affect air quality for weeks or even months. Exposure to pollutants released during the fire and after it was extinguished can significantly increase the risk of developing respiratory problems and other health issues. 

While some people experience only temporary irritation, others, especially children, older adults, and those with underlying medical conditions or breathing issues, may face more serious or long-term health effects.

The Cedars-Sinai Newsroom recently spoke with Irina Dralyuk, MD, director of Pediatric Pulmonology at Cedars-Sinai Guerin Children's, about the health risks associated with fire and smoke exposure, who is most vulnerable and what people can do to protect themselves.

What are the health dangers following a fire like the warehouse fire in Boyle Heights?

Following a fire, air quality can be affected for an extended period of time. Fires release a variety of chemicals and fine particles into the air, and many of those substances may not be immediately identified as materials continue to burn and break down.

The first few weeks after a fire are generally the most concerning, but people should remain cautious for at least two to three months. For individuals with respiratory diseases, weakened immune systems or heightened sensitivity to environmental pollutants, the health effects can last much longer, potentially up to a year.

Who should be especially cautious following a fire?

Several groups are at higher risk, including infants and young children, especially babies born prematurely, older adults, people with weakened immune systems, and those with chronic lung conditions such as asthma, chronic obstructive pulmonary disease (COPD) or cystic fibrosis.

However, even people with healthy lungs should take smoke exposure seriously. Environmental hazards from a fire can trigger inflammation or respiratory problems in otherwise healthy individuals, so everyone should take steps to protect themselves when air quality is poor.

What precautions can people take after a fire?

One of the most effective ways to reduce exposure indoors is by using air purifiers. It's important to choose a purifier that's appropriately sized for the room and to replace filters regularly. Home HVAC [heating, ventilation and air conditioning] filters should also be changed according to manufacturer recommendations.

If possible, limit activities that bring smoky outdoor air into the home. During periods of poor air quality, consider using fans instead of air conditioning, as it typically draws outside air into your living space. When spending time outdoors, wear a well-fitting mask on days when air quality is poor, especially during the weeks and months following a fire.

When should people seek medical attention?

Even mild symptoms such as an itchy or scratchy throat, irritated eyes, or persistent coughing are signs that smoke may be affecting your body and should not be ignored.

People experiencing coughing, wheezing, shortness of breath or difficulty breathing should see a doctor or head to an urgent care. Depending on the symptoms, a doctor may recommend diagnostic tests such as a chest X-ray or lung function tests. Your doctor might also listen to the lungs and determine whether medications, including inhalers, nebulizer treatments or oral medications, are needed to reduce inflammation, open the airways and improve breathing.

His labored breathing and exhaustion prompted him to see his physician, who ordered a battery of tests. Aster’s diagnosis: A rare cancer called a neuroendocrine tumor was causing a condition called carcinoid heart disease, and causing his heart to fail.

With treatment at the Cedars-Sinai Neuroendocrine Tumor Multidisciplinary Clinic, Aster is now back on the trail, his bike, his board and the court.

“I went from wondering how long I have to live to understanding that this can be managed,” Aster said. “I feel better than I have felt in years.”

Aster’s symptoms came on slowly over several months: crushing fatigue, bloating, loss of appetite and swelling in his legs and feet. Blood tests ordered by his primary doctor were normal, but a CT scan showed tumors in his liver, which were eventually diagnosed as stage 4 neuroendocrine cancer.

“We received the diagnosis the day we dropped the youngest of our four kids off at college,” Orr said. “We had other plans, so we just had to reset.”

Unable to sleep the night they got the news, Orr—who Aster said was his caregiver and support throughout this difficult time and credits with helping save his life—spent hours online. She clicked her way to the Neuroendocrine Tumor Research Foundation. The organization, a resource for research funding, patient education and support, directed the couple to  the Neuroendocrine Cancer Foundation, which referred them to Cedars-Sinai and its multidisciplinary clinic.

“We were concerned about Ken’s neuroendocrine tumors, which had spread to his liver and were making it difficult for his stomach to work normally,” said Andrew Hendifar, MD, who leads the clinic and is a professor of Medicine at Cedars-Sinai. “But we knew from experience that his heart failure would have to be treated first. We didn’t have a minute to lose.”

Neuroendocrine tumors begin in neuroendocrine cells, which connect the nervous system with the hormone-producing endocrine system. They can occur anywhere in the body.

Aster’s began in his small bowel and produced a hormone called serotonin, which thickened two of his heart valves and caused them to leak. The condition is called carcinoid heart disease.

Prashanth Venkatesh, MD, assistant professor of Cardiology in the Smidt Heart Institute at Cedars-Sinai, is the cardiologist on the neuroendocrine team.

“The pulmonary valve, which sends blood from the heart to the lungs, is notoriously difficult to evaluate with standard imaging techniques because of its location in the chest and the relative rarity of pulmonary valve disease in adults,” Venkatesh said. “Significant pulmonary valve involvement in carcinoid heart disease is hence very easily missed.”

Venkatesh, a congenital heart specialist, often employs more extensive imaging techniques for patients born with structural heart defects. Aster’s results showed there was a leak in his pulmonary valve as well as a leak in his tricuspid valve. Both valves needed to be replaced.

“When there is a leaky valve, which we call regurgitation, some of the blood in the heart goes in the wrong direction,” said Raj Makkar, MD, vice president of Cardiovascular Innovation and Intervention at Cedars-Sinai and the Karsh Distinguished Chair in Interventional Cardiology in the Smidt Heart Institute. “With leaky pulmonary and tricuspid valves, the blood that is supposed to go into the lungs can leak back toward the upper chamber of the heart.”

Aster’s pulmonary valve was replaced via a minimally invasive procedure in which a catheter was threaded up through an artery in the groin to maneuver the valve into its proper place. Four weeks later, Makkar replaced Aster’s tricuspid valve using a similar procedure. 

“Patients with carcinoid heart disease are going through a lot because of the neuroendocrine tumor, and traditional valve replacement surgery puts them at higher risk for complications,” Makkar said. “We pioneered testing of transcatheter tricuspid valve replacement around five years ago, and this was the option we chose for Mr. Aster.”

To address the neuroendocrine tumors on Aster’s liver, Alexandra Gangi, MD, director of the Division of Surgical Oncology and co-director of the Neuroendocrine Tumor Multidisciplinary Clinc, chose another minimally invasive approach: tumor embolization.

“We accessed the tumors with a catheter, through the artery in the groin,” Gangi said. “This allows us to block off the blood flow to the specific arteries that feed the tumors. This starves the tumors, and results in shrinking and tumor control.”

So far, Aster has avoided surgery and chemotherapy because of the nature of neuroendocrine tumors and the expertise of his care team in sequencing his therapies based on his sypmtoms.

“I think the difference between metastatic neuroendocrine tumors and most other types of gastrointestinal cancers is that we’re playing the long game,” Gangi said. “We often do the least invasive thing and save more aggressive options for when we really need them. These tumors tend to recur, but prognosis is generally good and patients can live a long time with them.”

Additional treatment or surgical procedures might be on the horizon, but today, Aster is doing well.

“We feel very fortunate that we were able to identify this as early as we did and intervene in the way that we did,” Hendifar said. “A few years ago, even six months ago, Ken wouldn't have been a candidate for minimally invasive valve replacements. He would have required open-heart surgery, and I'm not sure if the outcome would have been as good.”

Aster describes his current health as “great.”

“I just started cycling again in January, 13 months after the second valve replacement,” Aster said. “Now I'm doing a 25-mile ride in the hills two or three times a week with no problem. My heart feels as normal as can be.”

The 52-year-old has always enjoyed a high-energy lifestyle, managing the intensity of producing films and television shows (Ladder 49, Flight Plan, Top Gear, Wheeler Dealers) by eating healthy, running and biking along the Los Angeles River. After his daughter was born in 2020, Nieminen assumed his constant exhaustion was the typical kind that comes with sleepless nights caring for a newborn. Still, he and his wife, Kaisa, found it odd that picking up his daughter left him depleted.

“My battery was constantly drained,” Nieminen said. “Being physically active all my life, it was quite alarming. Deteriorating this quickly when I’m just over 50 seemed sort of dramatic.”

Nieminen also noticed his heart seemed to beat too fast at times and occasionally it would skip a beat, so in 2023 he made an appointment with Cedars-Sinai cardiologist Ronit Zadikany, MD. Zadikany diagnosed him with atrial fibrillation, an irregular heart rhythm that occurs when the upper and lower chambers of the heart beat out of sync. The condition tends to worsen with time and can cause the heart to beat too slowly, too quickly or irregularly, impeding blood flow. Common symptoms include fatigue, heart palpitations, dizziness and reduced stamina. Left untreated, atrial fibrillation can cause a slew of cardiovascular complications—including stroke.

Nieminen’s cardiologist referred him to Christine M. Albert, MD, MPH, an expert in atrial fibrillation and chair of the Department of Cardiology in the Smidt Heart Institute. Albert recommended cardioversion, a procedure commonly used to reset the heart to a normal rhythm. The results made Nieminen feel like himself again, but only for a day. A second cardioversion combined with a medication known to work for many people also had temporary effects.

Albert was determined to find Nieminen a treatment that would have long-term results. She suggested he might benefit from catheter ablation, a procedure that destroys cells and creates a small scar within the heart, breaking up or insulating the electrical signals causing the heart to beat out of sync. She connected him with Michael Shehata, MD, a cardiac electrophysiologist in the Smidt Heart Institute.

Shehata was leading a clinical trial investigating a new catheter ablation called pulsed field ablation. Rather than create scars, pulsed field ablation targets heart cells involved in an abnormal heart rhythm.

Nieminen underwent the procedure in January 2024.

“When other options fail, this procedure can be life-changing for patients,” Shehata said.

Pulsed field ablation is done by threading a catheter through a vein in a patient’s leg until it reaches the top chambers of the heart. Once in place, a cardiologist sends a high-voltage electrical impulse through the catheter. The energy penetrates cell walls and destroys specific heart cells, preventing abnormal signals from causing an irregular heartbeat. The procedure takes 30 to 60 minutes.

“The energy is delivered specifically to heart cells without injuring nerve cells, smooth muscle cells, or other, healthy cells,” said Shehata, who is also director of the Interventional Electrophysiology Laboratory at the Smidt Heart Institute. “For some patients with atrial fibrillation, this procedure may be safer than conventional ablation procedures that destroy small areas of heart tissue.”

Following U.S. Food and Drug Administration approval of several pulsed field ablation systems, the procedure is now available for use outside of a clinical trial.

Advances in treatment couldn’t come at a better time. Atrial fibrillation is the most common type of irregular heartbeat and deaths related to the condition have been increasing for more than two decades, according to the U.S. Centers for Disease Control and Prevention.

Today, Nieminen is back to long runs and cycling through his neighborhood. He also works with local organizations to advocate for safe walking and biking paths in Los Angeles. Most importantly, he can now lift his daughter into the air like the high-energy dad he is.

A device that was implanted to record Nieminen’s heart rhythm shows proof of his progress: He has been free from atrial fibrillation since getting pulsed field ablation.

“Don’t hesitate to share with your doctors when something feels off because you feel like you’re being a hypochondriac or you think it’s too insignificant to bring up,” he said. “As you get older, it’s especially important to listen to your body, eat right and stay active, and that doesn’t necessarily mean doing a 10K. Everything your mom would tell you growing up: Stay active, eat healthy, get sleep and get checkups with your doctor. Mom knew what she was talking about.”

Smidt Heart Institute cardiologist Janet Wei, MD, is one of the authors of a maternal health report from the National Academies of Sciences, Engineering, and Medicine, a nonprofit organization that reviews published research and provides advice to the U.S. government. Wei, associate professor of Cardiology and Biomedical Sciences, sat down with the Cedars-Sinai Newsroom to explain how pregnancy affects women’s hearts.   

How does pregnancy increase cardiovascular risk?

Pregnancy acts as a stress test for the heart and can uncover, or even worsen, problems like high blood pressure and diabetes. During pregnancy, the heart must work harder to support a growing fetus, and cardiac stress often continues after delivery.

Cardiovascular disease is the leading cause of pregnancy-related death in the U.S., yet most of these deaths are preventable. The National Academies of Sciences, Engineering, and Medicine report on maternal health highlights that although 57% of cardiovascular-related deaths occur between seven days and one year postpartum, preventive care is often focused on the prenatal and immediate postpartum period.

What are two takeaways from the report?

The committee reviewed published medical research and gathered input from a wide range of stakeholders, including clinicians, professional societies, advocacy organizations and patients.

Several takeaways became clear. The report recommends, for example, that clinicians treat pregnant women with chronic hypertension so that their blood pressure is reduced to less than 140/90 millimeters of mercury.  This is because consistently elevated blood pressure during pregnancy can cause pregnancy complications and increase a woman’s risk for developing cardiovascular disease.

The new guidelines also recommended that clinicians caring for patients with postpartum hypertension or other hypertensive disorders give their patients home blood pressure monitors and use a program that allows the patients to report their readings. This way, clinicians can adjust treatment and set clear thresholds for action. 

Cedars-Sinai is already doing this through a postpartum blood pressure monitoring program that sends patients home with a blood pressure cuff and allows them to transmit readings to their care teams. (Kimberly Gregory, MD, MPH, director of the Division of Maternal-Fetal Medicine at Cedars-Sinai, served as an adviser to the National Academies committee that created the maternal health report.)

How often should women visit a doctor in the year after giving birth?

How frequently a woman should see her doctor during the postpartum period depends on her cardiovascular risk. 

Not every woman can easily see a doctor or health specialist—especially in rural areas or when cost is a concern. Therefore, the National Academies report recommends the Health Resources and Services Administration use its telehealth, rural health and maternal health programs to reduce geographic, financial and system barriers to preventive cardiovascular services.

What can pregnant women do to protect heart health?

The National Academies created a resource for women that includes the following advice:

Share your history. Tell your healthcare team your family history of heart disease, especially early heart attacks or strokes, and your pregnancy history, including any past complications.

Keep postpartum follow-up appointments on your calendar. It’s important not to miss these appointments because risk for complications continues through the first year after delivery.

Take warning signs seriously—trust your instincts. If something feels wrong during pregnancy or after birth, seek care right away and tell providers that you’re pregnant or that you gave birth recently.

The study, “Real-World Outcomes of Transcatheter Tricuspid Valve Replacement: Analysis From the STS/ACC TVT Registry,” published in the Journal of the American Medical Association.

“These findings show that transcatheter tricuspid valve replacement is translating well from the clinical trial setting into routine practice across the United States,” said Raj Makkar, MD, vice president of Cardiovascular Innovation and Intervention at Cedars-Sinai, the Karsh Distinguished Chair in Interventional Cardiology in the Smidt Heart Institute, and corresponding author of the study. “In a large, older and medically complex patient population, we saw very high procedural success, near-complete elimination of tricuspid regurgitation, and rapid improvement in how patients feel and function.”

Tricuspid regurgitation occurs when the tricuspid valve does not close properly, allowing blood to flow backward in the heart. The condition is common in older adults and can lead to worsening heart failure symptoms, repeated hospitalization and increased risk of death.

Historically, open-heart surgery was often the only treatment option for this condition, but many older patients were not candidates because of age or other medical problems. Today, transcatheter tricuspid valve replacement offers a less invasive alternative in which doctors replace the damaged valve using a catheter, or tube, threaded through a blood vessel.

Researchers analyzed 1,034 attempted TTVR procedures performed between February 2024 and March 2025 at 82 medical centers across the U.S. The average patient age was 77.

The analysis found that more than 98% of patients had the valves successfully implanted. At 30 days post-procedure, more than 97% of patients had their condition improve to mild or minimal tricuspid regurgitation, and patients reported substantial improvement in symptoms, physical and social function, and quality of life.

Study authors note that early real-world outcomes were consistent with results from the TRISCEND II randomized trial of TTVR. Patients in this new study, however, experienced lower incidence of bleeding and heart block requiring electronic pacemaker implantation than patients participating in TRISCEND II. The current study also found that outcomes were generally consistent in patients with and without preexisting cardiac implantable electronic devices such as pacemakers, an important finding because these devices are common in patients with severe tricuspid valve disease.

“For patients with severe tricuspid regurgitation, treatment options have historically been limited, especially when surgery carries high risk,” said Aakriti Gupta, MD, assistant professor of Cardiology and study author. “What is especially encouraging here is that in real-world care, not just in a randomized trial, patients experienced meaningful improvement in symptoms and quality of life within only 30 days.”

Investigators said the results support the growing role of TTVR as a treatment option for patients with severe tricuspid regurgitation and highlight the importance of continued follow-up to understand longer-term outcomes.

Moody Makar, MD, associate professor of Anesthesiology at Cedars-Sinai, is also an author of the study.

The findings, published in Science Translational Medicine, could one day improve management of heart failure, in which the heart fails to pump enough blood to meet the body’s need for blood and oxygen. Poor use of oxygen by the heart is an early indicator of heart failure, which affects nearly 7 million people in the U.S.

“Our study shows how MRI could be used to quickly and noninvasively determine heart oxygen use in the clinic,” said Hsin-Jung Yang, PhD, director of Cardiac Imaging Research in the Biomedical Research Imaging Institute and corresponding author of the study. “With further research and development, this advance could unlock new frontiers in early diagnosis, personalized therapy and next-generation treatments for heart failure.”

The current gold standard for measuring heart oxygen use, coronary sinus catheterization, requires threading a thin, flexible tube called a catheter from a patient’s neck or groin into the heart's main vein. The procedure, which takes 30 to 60 minutes and involves injection of a contrast dye to guide the catheter, is too invasive for routine heart oxygen monitoring.

MRI uses radio waves, a strong magnet and a computer to create detailed images of areas inside the body. Standard MRI can only produce clear images of the heart, which moves with every beat and every breath, if patients hold their breath at points during the exam. And in order to use these images to measure oxygen, doctors have to take multiple MRI scans—a process that takes several minutes—and draw blood at the same time.

“The system we designed addresses the motion of the heart,” Yang said. “Patients do not need to hold their breath, and it can give precise numbers within three minutes.”

The team proved the accuracy of its MRI method by using it to measure heart oxygen use in patients with and without heart failure, and comparing its readings to readings obtained by heart catheterization.

“Noninvasive testing that detects issues in the heart’s use of oxygen can provide an early warning that heart failure is developing,” Yang said. “Now that we have promising cardiometabolic therapies lined up, earlier detection may allow us to take steps to prevent and treat the condition.”

David Underhill, PhD, chair of the Department of Biomedical Sciences, said the study makes a major contribution toward improving healthcare for heart disease, the No. 1 cause of death.

“Along with its potential for saving lives through early intervention for heart failure, this accessible tool could offer new avenues for cardiac research,” Underhill said. “It could allow us to study patients who have risk for, but no symptoms of, heart failure without exposing them to catheterization, contrast or radiation.”

Throughout her career, Cheng has maintained National Institutes of Health funding for research aimed at uncovering the drivers of cardiovascular aging. She has authored more than 450 scientific studies, many appearing in high-impact journals, including JAMA, Circulation and The New England Journal of Medicine.

Cheng identified differences in how males and females develop elevated blood pressure and demonstrated how people vary in their responses to COVID-19 vaccines over time. Her research has garnered multiple awards and contributed to Cedars-Sinai’s reputation as an international leader in biomedical sciences.

“Dr. Cheng is the perfect leader to build and enrich our already flourishing Department of Cardiology,” said Shlomo Melmed, MB, ChB, dean of the Medical Faculty and executive vice president of Medicine and Health Sciences. “We welcome her to this academic leadership role and look forward to the contributions she will make in strengthening the Smidt Heart Institute.”

Cheng, who succeeds Christine M. Albert, MD, MPH, has served on the editorial boards of major professional journals and on leadership committees for the American Society for Clinical Investigation, the American Heart Association and the American College of Cardiology.

She founded the largest COVID-19 clinical research program on the West Coast at the outset of the pandemic in 2020. More recently, she has led research to investigate the public health effects of the 2025 Los Angeles wildfires.

Cheng has mentored dozens of junior faculty members in cardiology, anesthesiology, neurology, obstetrics and oncology, taking special pride in advising early-career investigators as well as high school and college students.

“I look forward to supporting the Smidt Heart Institute’s talented clinicians and researchers as they work to improve the lives of those affected by cardiovascular disease,” Cheng said.  

Cheng received her bachelor’s degree from Harvard College and her medical degree from McMaster University in Canada, as well as a master of medical science degree from the Massachusetts Institute of Technology and a master of public health degree from Harvard University. She completed her internal medicine training at Johns Hopkins University and cardiology training at Brigham and Women’s Hospital, where she served as associate director of the Cardiovascular Imaging Core Laboratory.

In her new role, Cheng will lead strategic clinical, research and educational growth for the Department of Cardiology. As the new department chair, she will hold the Stephen R. Corday, MD, Distinguished Chair in Cardiology.

“Dr. Cheng has strengthened our institution and made many meaningful contributions through her research laboratory since joining Cedars-Sinai seven years ago,” said Eduardo Marbán, MD, PhD, executive director of the Smidt Heart Institute and the Mark Siegel Family Foundation Distinguished Chair. “We are excited for her to continue developing our world-class cardiology department.”

“Too often, when a young woman has heart disease symptoms, a physician will ignore those symptoms and tell her that she needs to lose weight,” said Bairey Merz, director of the Barbra Streisand Women’s Heart Center in the Smidt Heart Institute at Cedars-Sinai. “That’s because heart disease symptoms in women can be very different from what men experience. So it’s crucial that women know what to look for.”

Although heart disease is the leading cause of death among women in the U.S., according to the Centers for Disease Control and Prevention, most heart disease research has been conducted on men. And even though rates of heart disease and heart attacks are increasing among women 35 to 54 years old, they are less likely to receive evidence-based treatments such as statins and more likely to be told they are “too young” to have heart disease, Bairey Merz said.

“These delays and dismissals have had serious consequences,” she said. “The Women’s Ischemia Syndrome Evaluation [WISE] study that I led for the National Heart, Lung, and Blood Institute helped us better understand that heart disease doesn’t always look the same in women. That insight ultimately pushed the field to rethink and improve how we diagnose and treat it.”

Despite these advances, women with heart disease are still more likely to be misdiagnosed, underdiagnosed or undertreated—sometimes delaying care that could save their lives.

“The good news is that heart disease is largely preventable,” Bairey Merz said. “And for women in particular—who may not experience obvious symptoms or whose symptoms are subtle—knowledge is a powerful prevention tool.”

To explain what women should watch for, the Cedars-Sinai Newsroom spoke with Bairey Merz about what women can do to protect their hearts and advocate for the healthcare they need.

What are some of the biggest myths about heart disease?

Many people believe that heart disease primarily affects men, that heart attacks always involve crushing chest pain, or that cancer is the top cause of death. In reality, heart disease kills more women than all cancers combined, yet fewer than half of women recognize it as their greatest health threat.

While men tend to develop cardiovascular disease earlier, women are more likely to experience poorer outcomes.

Why are heart attack rates increasing among younger women?

For decades, heart attack death rates declined sharply, thanks to improved research, standardized treatment guidelines, and widespread use of effective medications and procedures. While heart attack deaths are still much lower than they once were, the increase in heart problems among younger adults is concerning.

Researchers are looking into exact causes for the increase, but we know that contributing factors include low levels of physical activity and prolonged sedentary behavior, rising rates of diabetes and obesity, chronic stress, and environmental exposures such as air pollution.

What does a heart attack feel like for women?

The so-called “Hollywood heart attack”—tingling in the left arm that leads to sudden, crushing chest pain—is common in men and can occur in women as well. But many women experience subtler symptoms, including shortness of breath, nausea, unusual fatigue, back or jaw pain, or chest discomfort that doesn’t feel severe or dramatic.

Because these symptoms don’t match common expectations of a heart attack, they may be overlooked or dismissed. Anyone experiencing them should seek medical care immediately.

What causes heart attacks in women?

An increasing number of heart attacks are occurring in people without significant blockages in the major coronary arteries, a pattern seen more often in women. While men’s heart disease more commonly involves blockage in large arteries, women are more likely to experience dysfunction of the heart’s smaller blood vessels. This condition—called ischemia with no obstructive coronary artery disease [INOCA]—can cause reduced blood flow to the heart even when major arteries appear clear.

Even women who are physically fit can develop INOCA. In the past, if a woman had heart attack symptoms but a “normal” angiogram showing clear major arteries, her condition might not have been recognized. Continued awareness and ongoing education around INOCA are helping clinicians better diagnose and treat these patients.

What is a normal heart rate for women?

A normal resting heart rate for most adults is between 60 and 100 beats per minute, according to the American Heart Association. Because women’s hearts are typically smaller, their resting heart rate may run slightly higher than men’s. Women should consult their doctor if their resting heart rate is below 60 or above 100 beats per minute when not exercising.

How can women protect heart health and prevent heart disease?

Heart disease develops silently over decades. While heart disease can be managed with highly effective treatments, prevention is the most powerful strategy.

An estimated 80% of heart disease cases are preventable with lifestyle modifications. These include staying current with annual screenings and knowing cholesterol, blood pressure and blood sugar levels; exercising at least 30 minutes daily; breaking up prolonged sitting because a sedentary lifestyle is considered as strong a risk factor as smoking; managing stress; getting seven to nine hours of sleep; avoiding smoking; and following a nutritious diet.

A Mediterranean-style, largely plant-based diet rich in fruits, vegetables, nuts, beans, whole grains, olive oil and lean proteins is recommended. Parents are encouraged to help ensure their children make healthy food choices, too.

Heart health isn’t about deprivation. It’s about building lifelong habits that prevent disease before it starts.

Reid had been diagnosed with heart failure at Cedars-Sinai after experiencing fatigue and shortness of breath. The condition occurs when the heart is too weak to pump enough blood throughout the body, causing fluid to build up.

Reid told Good Morning America co-anchor Michael Strahan he initially dismissed his symptoms. He urged others—especially people of color—to seek medical care when something feels wrong.

“A lot of times, we don’t go because we don’t want the bad news, or we’re too busy just hustling, trying to make it from day to day,” Reid said. “And we … feel like we don’t got time, or we’ll get over it. Well, you might not.”

Jones told Good Morning America that during a follow-up visit, it was clear medications were no longer controlling Reid’s condition.

“He came in very swollen again,” she said, “and that is a little unusual in somebody who’s been started on treatment.”

DiChiacchio told Good Morning America that bloodwork revealed the condition was worsening and Reid needed an immediate heart transplant.

“So when we think about status for a heart transplant,” DiChiacchio said, “he was very high on that list because of how ill he was and really dealing with a kind of life or death situation.”

Days later a donor heart became available, and DiChiacchio and team successfully completed the transplant.

 Reid told Strahan he is grateful for a second chance at life.

“This thing is … a beautiful life,” he said. “And, you know, I wanna be around for it.”

According to the Centers for Disease Control and Prevention, 6.7 million U.S. adults have heart failure. Risk factors include high blood pressure, diabetes and coronary artery disease, though regular exercise, adequate sleep and proper nutrition can lower risk.

One year after wildfires tore through Pacific Palisades and Altadena, upending hundreds of thousands of lives across Los Angeles, many residents are still navigating recovery—rebuilding homes, reestablishing routines and managing the emotional aftershocks of disaster.

As communities mark the anniversary, questions about resilience feel especially relevant: What does it mean to be resilient? Do resilient people share common traits? Can resilience be strengthened over time?

The answers, said Itai Danovitch, MD, chair of the Department of Psychiatry and Behavioral Neurosciences at Cedars-Sinai, are layered and complex.

“The notion that resilience is just pulling yourself up by your bootstraps is an oversimplification,” Danovitch said. “When we think about resilience, we must avoid applying our own framework to somebody else’s situation. Rather, we need to recognize that there may be different conditions shaping their response.”

The Cedars-Sinai Newsroom recently spoke with Danovitch about the science of resilience, the role of meaning and social connection, and what the past year reveals about resilience as Angelenos continue to recover and adapt.

What is resilience?

Resilience is often misunderstood. In reality, it is the capacity to adapt—to focus on what can be brought under your control so you can better cope with what you cannot control. At its core, resilience involves flexibility: adjusting expectations, behaviors and coping strategies in response to changing circumstances.

Do resilient people share common traits?

There isn’t a single profile for resilience because people differ widely in their skills, resources and circumstances. An artist, a professional athlete and a surgeon may each rely on very different strategies to navigate stress and adversity. Some people have a more positive outlook, and others are more cautious and skeptical. Both approaches can be valuable. Faith and spirituality can serve as anchors for some people, while others find different ways to ground them in challenging times. There are multiple ways to respond to the world around us, and resilience is less about having the “right” traits and more about being able to use the tools available to us in ways that fit our lives.

Are there shared building blocks?

While resilience looks different across individuals, a related area of research focuses on meaning-making, a concept closely associated with psychiatrist and Holocaust survivor Viktor Frankl, author of Man’s Search for Meaning. Frankl argued that even in the face of profound suffering, the ability to find purpose can help preserve one’s sense of self. If you can make or find meaning, you can adapt, and if you can adapt, you can survive.

What else shapes resilience?

Like most psychological characteristics, resilience is shaped by biology, psychology and social environment. Early life experiences matter. Stability, love and support can strengthen coping skills, while trauma also can leave lasting imprints. But resilience cannot be predicted by childhood experiences alone. Developmental experiences interact with biological predispositions in ways that aren’t always linear or predictable.

Can resilience be improved?

Yes. There is substantial research on how to recover from adversity; I’ll simplify it into four broad categories.  The first is improving emotional awareness—learning to recognize, name and express feelings. This awareness makes emotional regulation possible, whether through taking a timeout during emotional distress or practicing mindfulness or breathing exercises. The time to manage a highly charged conflict is not when you’re overwhelmed, but when your mind and body are calm enough to access your own wisdom. Frankl’s insight is relevant here: While you can’t always control your circumstances or feelings, you can control your attitude and response. The second category involves setting boundaries and expectations, which allows people to express agency and protect themselves emotionally or physically. The third is self-care—including adequate sleep, proper nutrition, physical activity and stress management. The fourth is meaning-making and social connection—cultivating relationships, community and experiences that provide a sense of purpose.  One important note: It’s easy to talk about strengthening resilience. It’s much harder to practice it consistently. 

What can the L.A. wildfires reveal about community resilience?

The story is still unfolding. Recovery isn’t cut and dry, and it doesn’t end just because it’s been a year. Disaster research shows emotional responses often emerge in phases. There’s the initial crisis and response people must navigate, and then there are phases of the psychological effects that tend to surface later. The continued impact on families and communities remains profound. We’ll continue to see regrowth and rebuilding as people navigate new challenges and curveballs. The bottom line is that it’s important to remember that flexibility—both in how resilience is defined and how it’s practiced—is central to understanding recovery from adversity.

“Wildfires that spread into urban areas have proven to be extremely dangerous because of how quickly they move and what they burn and release into the environment,” said Susan Cheng, MD, MPH, vice chair of Research Affairs in the Department of Cardiology in the Smidt Heart Institute and senior author of the study, published in JACC. “Our research suggests the Eaton and Pacific Palisades fires had an immediate effect on people’s health.”

The Cedars-Sinai Emergency Department is located on the academic medical center’s main campus, about 10 miles from Pacific Palisades and about 20 miles from Altadena, the locations where the largest L.A. fires ignited in January 2025. Investigators collected data on emergency department visits during the 90 days after the fires started, from Jan. 7 to April 7, 2025. They compared this data with emergency visit data collected during the same calendar period in the years 2018 through 2024. 

Although there wasn’t a significant difference in total emergency department visits during the first 90 days following the start of the wildfires in 2025 as compared with other years, there was a drastic increase in emergency department visits for certain conditions. Investigators found a 118% increase in visits for general illness, 46% increase in the number of visits for heart attack, and a 24% increase in visits for pulmonary illness when compared to the average rate of these conditions diagnosed during the same time window in the past seven years. 

“Fine particles released by wildfires can enter the body and cause injury, particularly to the heart and lungs,” said Cheng, who is also the Erika J. Glazer Chair in Cardiovascular Health and Population Science in the Smidt Heart Institute at Cedars-Sinai. “Stress related to the fires may also contribute to a broad range of health issues.” 

The investigators found that abnormal blood test results related to general illness more than doubled in the 90-day period in 2025 as compared with that period in previous years. This is a finding not previously reported after major wildfires, according to the investigators.

“Abnormal blood test results could indicate that the body is responding to an external stressor such as toxins in the air,” said Joseph Ebinger, MD, MS, associate professor in the Department of Cardiology and first author of the study. “This study is an important step toward understanding how the Eaton and Palisades fires may have affected Angelenos’ health. We need more research to determine what we can do to mitigate any remaining risks and protect people from fire harm in the future.” 

This study is part of the larger LA Fire HEALTH Study, a research collaboration that seeks to determine the health effects of the fires that ignited in January 2025 in L.A. County. Investigators with Cedars-Sinai; the Harvard T.H. Chan School of Public Health; the Keck School of Medicine of the University of Southern California (USC); Stanford University; UCLA; the University of California, Davis (UCD); the University of California, Irvine (UCI); the University of Texas at Austin; and Yale University plan to study the impacts of the fires for the next 10 years.

“Our AI model addresses a critical need,” said David Ouyang, MD, adjunct assistant professor in the Smidt Heart Institute at Cedars-Sinai and co-corresponding author of the study. “Many hospitals and clinics, especially in rural areas, do not have cardiologists or sonographers on staff. By generating accurate automated reports for physicians, we could improve access to this important diagnostic technology.”

The AI model investigators created, called EchoPrime, is a type known as a foundation model. These models are trained on massive datasets and can perform multiple tasks, including assessing ultrasound images and evaluating clinical report text. EchoPrime was trained on greater than 10 times more data than prior AI foundation models for echocardiography, making it the largest such model to date, according to the investigators. EchoPrime analyzes ultrasound images, then produces a verbal summary of heart function and structure meant to assist clinicians in diagnosing a patient.

The team trained EchoPrime on more than 12 million videos paired with cardiologists’ written interpretations of the tests. They then tested the model on data from Kaiser Permanente Northern California, Cedars-Sinai Medical Center, Stanford Health Care, Beth Israel Deaconess Medical Center in Boston, and Chang Gung Memorial Hospital in Taiwan. The investigators found that EchoPrime outperformed other foundation models for interpreting echocardiograms and matched or exceeded the performance of AI models designed to perform a single ultrasound task. It was also able to detect rare diseases of the heart.

The investigators are now conducting randomized clinical trials that compare reports generated by EchoPrime with those produced by cardiologists and sonographers. The goal is to confirm the accuracy of the model and ensure it is useful to cardiologists.

“This remarkable study from Dr. Ouyang and colleagues builds on several years of AI-enhanced imaging science at Cedars-Sinai,” said Sumeet Chugh, MD, vice dean and chief artificial intelligence health research officer at Cedars-Sinai. “EchoPrime is a unique foundational model that could potentially democratize AI-powered echocardiography interpretation on a global scale.”

Eduardo Marbán, MD, PhD, executive director of the Smidt Heart Institute at Cedars-Sinai, will give the George E. Brown Memorial Lecture at the American Heart Association Scientific Sessions 2025 in November in New Orleans. The Association created this lecture in 1935 to honor the memory of clinician and researcher George E. Brown, MD, and every year selects a distinguished scientist to share advances in cardiovascular science. Marbán will present “Discovery Arc From Cell Therapy to Novel Noncoding RNA Drugs.” Marbán’s laboratory was the first to isolate and culture human heart cells capable of repairing damaged tissue.

Also at Scientific Sessions, Jennifer Van Eyk, PhD, director of Basic Science Research in the Barbra Streisand Women’s Heart Center, will be honored with the 2025 Council on Basic Cardiovascular Sciences Distinguished Achievement Award.

Van Eyk, the Erika J. Glazer Chair in Women’s Heart Health, is an international expert in clinical proteomics, the study of proteins in the body and how diseases affect those proteins. Her work has shown that proteins surpass genes as a source of real-time insights on what’s happening—and what is going to happen—inside the body. Much of her research focuses on how heart disease affects men and women differently at the molecular level.

“It is a privilege to see Dr. Van Eyk honored by the Association for nearly three decades of work in cardiovascular research,” said Marbán, the Mark Siegel Family Foundation Distinguished Chair. “This recognition reflects her profound impact on science and patient care, and we commend her for her commitment to excellence as she continues to pioneer earlier detection for conditions such as cardiovascular disease.”

Among Van Eyk’s most recent efforts is the development of remote blood sampling, which allows people to mail in samples for analysis and leads to faster, more personalized health assessments.

“This award highlights the incredible progress we’ve made in using proteomics to understand heart disease,” said Van Eyk, director of the Advanced Clinical Biosystems Research Institute and professor of Cardiology, Biomedical Sciences and Pathology and Laboratory Medicine. “By studying proteins, we’re moving closer to detecting conditions like heart failure before symptoms appear. Our goal is to make early diagnosis as simple as mailing in a blood sample.”

Ananth Karumanchi, MD, professor of Medicine and director of the Renovascular Research Center, is the recipient of the Association’s 2025 Excellence Award for Hypertension Research—one of the highest honors in the field. Karumanchi, the Medallion Chair in Vascular Biology, received the Excellence Award for Hypertension Research at the American Heart Association Hypertension Scientific Sessions in September in Baltimore. The award honors scientists whose work has significantly advanced understanding and treatment of high blood pressure and related conditions.

Karumanchi’s work focuses on hypertension during pregnancy. His particular focus is preeclampsia, a serious blood pressure condition that can be fatal and increases a woman’s risk of heart disease, heart failure and stroke later in life. He is currently leading an international team studying how the placenta impacts heart health in mothers and infants. The project builds on Karumanchi’s earlier work, which pinpointed a protein in the blood that could help doctors detect preeclampsia earlier.

“I’m honored to have received this award from the American Heart Association,” Karumanchi said. “It underscores the dedication of our team as we work to better understand and treat hypertension and preeclampsia and improve cardiovascular health for mothers and babies.”

Jiun-Ruey Hu, MD, MPH, a fellow in interventional and structural cardiology in the Department of Cardiology, has also been selected as an Association award recipient. He will be recognized at this year’s Scientific Sessions as the winner of the 2025 Kidney in Cardiovascular Disease Educational Tools Contest.

Hu mentored a medical student (Sara Pollanen) in creating a digital tool to help clinicians treat patients with cardiorenal syndrome, a complex condition involving the heart and kidneys. Hu previously won the award from the Association in 2022 while completing his first fellowship at the Yale School of Medicine.

“The Cedars-Sinai Health Sciences University congratulates our faculty members on their well-deserved recognition from the American Heart Association,” said Shlomo Melmed, MB, ChB, executive vice president of Medicine and Health Sciences and dean of the Medical Faculty. “Their prestigious honor awards and novel discovery presentations reflect the finest in cardiovascular science and clinical care.” 

The 2025 Scientific Sessions meeting is chaired by Joanna Chikwe, MD, the Irina and George Schaeffer Distinguished Chair in Cardiac Surgery in the Smidt Heart Institute.

Under her direction, the sessions will showcase pivotal late-breaking clinical trials that address major questions in the management of atrial fibrillation, valvular heart disease, heart failure and coronary disease.

A national leader in mitral valve reconstruction and robotic cardiac surgery, Chikwe is chair of the Department of Cardiac Surgery at Cedars-Sinai.

“It is an honor to guide this year’s American Heart Association programming and ensure that rigorous science is at the forefront of the meeting,” said Chikwe, the Irina and George Schaeffer Distinguished Chair in Cardiac Surgery. “It will be wonderful to participate alongside dozens of faculty members and trainees from Cedars-Sinai.”

Chikwe will lead a session on advances in the management of mitral and tricuspid valve disease and will chair a session about robotic innovations in valvular heart disease surgery.

Also at the meeting, Eduardo Marbán, MD, PhD, executive director of the Smidt Heart Institute, will present “Discovery Arc From Cell Therapy to Novel Noncoding RNA Drugs,” the George E. Brown Memorial Lecture. The Association’s Council on Basic Cardiovascular Sciences selected Marbán for this honor, which was established in 1935 in memory of clinician and researcher George E. Brown, MD.

In addition, Christine M. Albert, MD, MPH, chair of the Department of Cardiology, will participate in a discussion of the late-breaking science presentation “Dilemmas in Antithrombotic Therapy in AF Care Post Procedures.” Albert’s own research focuses on the epidemiology, risk stratification and prevention of sudden cardiac death and atrial fibrillation.

“I noticed it most when I lay down to sleep,” said Scott, whose family has lived in Altadena for three generations. “I could hear wheezing, I could hear a lot of wheezing, which I had never experienced before.”

Scott is not the only one. Since the wildfires ravaged the area, residents have been seeking help for symptoms that indicate difficulty breathing, such as coughing, wheezing, chest tightness and fatigue.

“We know that heavy exposure to wildfire smoke can have a delayed and long-term impact on lung function,” said Talar Kavafyan, MD, medical director of the ambulatory care center at Huntington Health, an affiliate of Cedars-Sinai. “Following the devastating fires our community experienced in January, providing enhanced pulmonary care is an important step in recovery—and an important example of how Huntington is dedicated to improving community wellbeing.”

So dedicated that, in response to the potential health impact in the wake of the fires, Huntington Health recently expanded pulmonary medicine for the community at the Huntington Ambulatory Care Center (HACC).  

The expansion came just in time for Scott, who continued to have difficulty breathing months after the flames were extinguished. “I began to talk to my primary physician about it,” Scott said, “and I kept telling her I don't feel like I'm getting a good capacity of air.”

That is a symptom that Raj Dasgupta, MD, has heard from dozens of patients who lived through the wildfires.

“It's understandable to be concerned when someone is having difficulty breathing [dyspnea], which is the sensation of not being able to get enough air, tightness in the chest, or working harder to breathe,” said Dasgupta, associate professor of Clinical Medicine and associate program director of Huntington Health’s Internal Medicine Residency Program. “By offering a wider range of tests in an outpatient setting, we can potentially detect pulmonary issues earlier and initiate treatment more quickly, which can lead to better outcomes and help bring some peace of mind to our patients who might be experiencing pulmonary issues right here in our community.”

Conditions frequently treated by the center’s physicians include asthma; chronic bronchitis and bronchiectasis; persistent cough; chronic obstructive pulmonary disease (COPD); lung scarring, or fibrosis; and sarcoidosis, an autoimmune disease that causes growths on the lungs.

“When you arrive at HACC, the first step of treatment is to collect information about your lungs and their function,” Dasgupta said. “We do this by conducting a breathing test in our office called spirometry, which is a valuable tool for diagnosing, monitoring and evaluating lung function. It provides essential information for managing lung conditions and improving respiratory health. After additional tests and evaluations, we then discuss the next steps to best support your lung health. Remember,  difficulty breathing and coughing can have various causes, and it's essential to seek medical evaluation for a proper diagnosis and treatment.” 

The pulmonary clinic is open every second and fourth Tuesday of the month from 1–5 p.m. For an appointment, call (626) 397-5711.

“We continue to expand the number of clinicians, surgeons and physician-scientists coming together to address the most challenging heart conditions,” said Eduardo Marbán, MD, PhD, executive director of the Smidt Heart Institute. “As our program grows, we remain committed to delivering care guided by extensive research.”

Fetal Cardiology

Mark Sklansky, MD, is a leader in fetal echocardiography, the detailed evaluation of the heart prior to delivery. He is medical director of Pediatric and Fetal Cardiology Outreach in the Smidt Heart Institute and Guerin Children's, where he uses ultrasound to identify heart conditions before birth and brings his expertise to the broader community.

Prenatal detection of heart problems allows fetal cardiologists, in partnership with obstetricians, maternal-fetal medicine specialists and neonatologists, to create a treatment plan for when the baby is born. In some cases, pediatric cardiac interventionalists, working with maternal-fetal medicine specialists, can perform a minimally invasive procedure to correct the heart defect before birth. In other cases, newborns can undergo lifesaving surgery or catheter-based therapies within hours after delivery.

Prior to joining Cedars-Sinai, Sklansky founded the Children’s Heart Center at UCLA where he was also chief of Pediatric Cardiology. He has authored or co-authored more than 100 scientific papers, including the American Heart Association’s scientific statement on the diagnosis and treatment of fetal cardiac disease.

Cardiac Surgery

Laura DiChiacchio, MD, PhD, is director of Extracorporeal Membrane Oxygenation, a form of life support that temporarily does the work of a person’s heart or lungs.

DiChiacchio also directs the Ex Situ Perfusion Program. Under DiChiacchio’s leadership, the team uses specialized machines to keep donor organs alive outside of the body and to improve the function of thoracic organs following transplantation. The team also conducts translational research on thoracic organ recovery and reconditioning. 

DiChiacchio is a cardiac surgeon who focuses on adult heart and lung transplantation. DiChiacchio completed a fellowship in thoracic transplantation and mechanical circulatory support in the Smidt Heart Institute Department of Cardiac Surgery and a fellowship in cardiothoracic surgery at the University of Utah.

Organ Preservation

As director of Heart and Lung Protection and Management, Yoshikazu Suzuki, MD, procures donor organs for patients awaiting transplant, ensuring safety and reliability through each step. He uses the latest technologies to ensure organs are well-preserved, and he is tasked with creating an accessible database of donor hearts and lungs.

Previously, Suzuki was clinical associate professor in the Division of Cardiovascular Surgery at the Perelman School of Medicine at the University of Pennsylvania.

Pediatric Interventional Cardiology

Stephen Nageotte, MD, is an interventional cardiologist, an expert in using minimally invasive procedures to diagnose and treat children and adults born with a heart condition. These procedures involve using a thin, flexible tube called a catheter to view the heart and repair anatomical abnormalities, such as narrowed blood vessels or an unclosed hole in the heart. Nageotte directs the Congenital Catheterization Laboratory in the Smidt Heart Institute and Guerin Children’s. 

Nageotte joins Cedars-Sinai from Loma Linda University Children’s Hospital, where he was director of the Pediatric Cardiac Catheterization Laboratory and an associate professor. Nageotte also conducts research and has authored several peer-reviewed papers on congenital heart disease and treatments.

The Smidt Heart Institute’s cardiology, heart and vascular surgery programs are rated in the top 10 in the U.S. and #1 in California by U.S. News & World Report.

“This novel program brings Cedars-Sinai’s exceptional expertise in heart care to a unique population: professional athletes and athletically minded individuals,” said Eli Friedman, MD, who has been appointed director of the Sports Cardiology Program.

The Sports Cardiology Program is part of the Department of Cardiology chaired by Christine Albert, MD. It is an extension of the sports medicine expertise already offered by Cedars-Sinai, where physicians serve as medical advisers for several elite sports teams. Cedars-Sinai also is the Official Medical Provider for the LA28 Olympic and Paralympic Games. 

“We offer specialized care for people who exercise and are concerned about heart health, whether or not they have been diagnosed with heart disease,” Friedman said. “Exercise and athleticism are wonderful priorities, but it’s important to ensure safety in those at risk.” 

The program also will evaluate athletes for heart conditions, and it can screen people for heart issues before they participate in a sport.

Friedman brings substantial experience to his new role. Before joining Cedars-Sinai, he was medical director of Sports Cardiology at Baptist Health South Florida in Miami and director of Sports Cardiology at the Miami Cardiac & Vascular Institute.

He has also been team cardiologist for more than a dozen professional and college sports organizations. Friedman has authored several scientific papers on athletes’ heart care and conducts research on cardiac conditions in athletes—as well as a genetic heart condition called hypertrophic cardiomyopathy, the most common cause of sudden cardiac arrest in young athletes. 

“Our region is among the most sports-conscious in the world. By building on our considerable strengths to establish the Sports Cardiology Program, the Smidt Heart Institute reaffirms its commitment to our community, and to LA28,” said Eduardo Marbán, MD, PhD, executive director of the Smidt Heart Institute and the Mark S. Siegel Family Foundation Distinguished Professor. “Under Dr. Friedman’s leadership and experience, we will build an outstanding program, helping athletes to continue doing what they love most.”

Led by interventional cardiologist Raj Makkar, MD, the six-and-a-half-year award from the Patient-Centered Outcomes Research Institute (PCORI) will fund a multi-center clinical trial of patients 50 and older who were born with a bicuspid aortic valve, a condition in which the aortic heart valve has two flaps regulating the flow of blood rather than the normal three. People with this condition typically develop aortic stenosis, when the aortic valve becomes so narrow that it impedes blood flow out of the heart.

Bicuspid aortic valve is the most common congenital heart condition, affecting approximately 2% of people, but little data exists comparing current treatments.

Heart valve disease can cause subtle symptoms at first but progress to heart failure if not diagnosed and treated early. Both surgery and transcatheter procedures are currently used to treat aortic stenosis. Transcatheter procedures use a thin, flexible tube called a catheter to reach the damaged valve. They are considered minimally invasive and are often recommended for patients who are at high risk for complications during surgery.

“Transcatheter aortic valve replacement has changed the paradigm for nonsurgical treatment of aortic stenosis, but it needs to be studied more rigorously in patients with bicuspid aortic valves,” said Makkar, a principal investigator of the study and vice president of Cardiovascular Innovation and Intervention at Cedars-Sinai. “We look forward to addressing this important evidence gap with this PCORI-funded randomized controlled trial in collaboration with our esteemed co-investigators.”

Patients with bicuspid aortic valve stenosis enrolled in the clinical trial will be randomly assigned to have their aortic valve replaced via open-heart surgery or by a transcatheter procedure. Investigators will review results from both groups to understand which option results in better health outcomes.  

The inaugural director of the Karsh Division of Interventional Cardiology, Makkar is an authority in minimally invasive approaches to treating heart valve disease.

“The Smidt Heart Institute at Cedars-Sinai is a leader in both heart surgery and minimally invasive heart procedures,” said Eduardo Marbán, MD, PhD, executive director of the Smidt Heart Institute at Cedars-Sinai and the Mark S. Siegel Family Foundation Distinguished Professor. “This study reflects our commitment to advancing heart research and care.”

“This research is a prime example of how Cedars-Sinai fosters innovation and brings leading-edge and clinically effective research directly to patient care,” said Shlomo Melmed, MB, ChB, Cedars-Sinai's executive vice president of Medicine and Health Sciences and dean of the Medical Faculty. “The findings from this clinical trial will help doctors globally advise their patients born with a bicuspid aortic valve on the best and safest approach for treating their cardiac condition.”

The award has been approved pending completion of a business and programmatic review by PCORI and issuance of a formal award contract. PCORI is a non-profit organization with a mission to fund research designed to provide patients, their caregivers and clinicians with the evidence-based information needed to make better-informed health care decisions.

The tone was urgent: “Please pick up your child now.” Moments later, Kim, director of the Division of Pediatric Surgery, learned his Pacific Palisades community was on the brink of a wildfire evacuation order. He raced home to help his family pack, but he felt certain, based on past experience, they’d be back soon.

The Kim family is now marking four months in a Santa Monica apartment: The L.A. wildfires, which began Jan. 7, 2025, and also devastated the Altadena community, destroyed their home.

Kim’s daughters, 13 and 16, were uprooted from their home, school and community. In a flash, they were separated from friends and unable to participate in local activities. And now, with summer break approaching, they and many other affected students could experience more disruption in their daily routines.

Connections and Consistency

Suzanne Silverstein, MA, ATR, founding director of Cedars-Sinai’s Share & Care, a program at 30 L.A.-area schools helping at-risk children through trauma, said parents should be prepared to guide children—many of whom are still grieving—through that disruption.

“The Pacific Palisades and Altadena communities were very tight-knit, and they are still suffering,” Silverstein said. “Children and parents have had to deal with losing homes as well as their community connections. It’s a double whammy, and it’s normal to still be grieving.”

Silverstein said children in the Share & Care program have received donated items, and she often hears them say, “I had this in my house that burned down.”

She added, “They’re also struggling because they’ve changed schools—their family moved, or their original school is no longer there—and their friends are at different schools. They’ve had to start over.”

Silverstein emphasized the importance of maintaining connections, especially during the summer break. She encourages parents to set up playdates with friends who have moved to different areas, saying, “Whole families can reconnect, which can be a gift to have everyone together for some positive experiences, and to see that everyone is OK.”

Consistency also is key, Silverstein said. If children have always attended summer camp and their camp is taking place this summer, it could be healing for them to go again, “if it’s something that’s familiar to them and something they can connect to, from before the fire.”

An art therapist, Silverstein also encourages children to express themselves in the ways they are most comfortable.

“Is it writing, is it drawing, is it through poetry or acting? Give them more of those experiences this summer,” she tells parents.

Art is a healing tool in Share & Care—younger children are encouraged to draw what they’re experiencing, while older ones are encouraged to write or draw in a journal, and then share if they’d like.

Also taught are mindfulness, calming breathing techniques, and how to sit quietly together and listen to what others in the group are sharing.

These are activities parents can continue with their children during summer recess, Silverstein said.

“We’ve been teaching parents the breathing techniques we’ve used with their children,” she said. “Parents also can benefit, as this continues to be a stressful and overwhelming time for them, too.”

Silverstein noted that the healing process is different for every child, and a strong parent-child connection can lead the way in best addressing the needs of each individual.

Leaning on Each Other

In the weeks following the fire, Kim’s family stayed in Orange County with relatives. He remembers kindness on full display when his daughters—competitive swimmers—were invited to swim with the local team. His older daughter took them up on the team’s offer.

“That was a huge part of maintaining some semblance of connection, and it helped her recovery,” he said, because she could participate in a routine activity she enjoys while also making new friends.

Kim said both daughters, as well as he and his wife, have benefited from social time with former neighbors and friends who are recovering from the fires.

“Talking about the complete loss we’ve experienced with people who’ve also been through it is a huge help,” he said.

Kim said he hopes to create a “normal” summer experience for his daughters, even though the family is living in a different place—filling it with swim meets and a vacation to the East Coast, a family tradition. His older daughter also will volunteer at Cedars-Sinai, an activity she finds fulfilling.

For the Kim family, time together may prove to have been the most healing.

“My wife and I were quite concerned about the stress of this trauma on the girls,” he said. “Earlier on, there were teary days and sleepless nights, but it’s been a while since we’ve seen emotions bubble up. We continue to watch them closely and make sure they know we’re here for them. I’m in awe of their resilience—it gives me strength to see them get up every morning, go to school and carry on to the next day.”

As the school year ends, these moments are more important than ever.

“We can’t get back the things we lost,” Kim said, “but we can help each other write the next chapter.”

 In 2021, Emerson and a team of Cedars-Sinai surgeons performed the world’s first robotic lung transplant. Since then, the medical center has completed the most robotic lung transplants in the world. The innovation uses tiny incisions to reduce pain, complications and recovery time.

Emerson, associate professor of Cardiac Surgery in the Smidt Heart Institute at Cedars-Sinai, will further strengthen and unify the thoracic and abdominal transplant arms of the Comprehensive Transplant Center, which ranks among the top 10 in the U.S. by volume. Emerson was also recently appointed program director of the Accreditation Council for Graduate Medical Education thoracic surgery residency and fellowship programs at Cedars-Sinai, an important role overseeing the education and training of junior surgeons. 

“Dr. Emerson’s leadership helped guide our teams to perform more transplants in 2024 than we ever have before, all while achieving exceptional patient outcomes,” said Irene Kim, MD, director of the Cedars-Sinai Comprehensive Transplant Center and the Esther and Mark Schulman Chair in Surgery and Transplantation Medicine.

Emerson will continue as associate surgical director of Heart Transplant and Mechanical Circulatory Support, director of Robotic Cardiac Surgery, and director of the Accreditation Council for Graduate Medical Education Fellowship Program. In addition, Emerson is on the editorial board of The Annals of Thoracic Surgery.

“It’s an honor to help give the opportunity for a longer life to the many people around the world who are desperate for a heart or lung transplant, as well as those patients in need of specialized cardiac surgery,” Emerson said.

Emerson’s research lab focuses on advanced machine perfusion techniques that better preserve and reduce damage to organs before they’re transplanted, which can boost success rates and improve the rates of transplants. His most notable contributions include a landmark study of lung transplantation for end-stage COVID-19 lung disease, published in the New England Journal of Medicine, and a national analysis of how devices that assist the heart called LVADs can improve outcomes in older adult patients, published in the Journal of the American College of Cardiology. Additionally, Emerson and Cedars-Sinai colleagues are leading the creation of a multi-institutional registry to better understand the benefits of robotic lung transplant.

“Dr. Emerson has been a remarkable colleague and role model for the cardiac surgery team,” said Joanna Chikwe, MD, professor and chair of the Department of Cardiac Surgery and the Irina and George Schaeffer Distinguished Chair in Cardiac Surgery in the Smidt Heart Institute. “He also is a patient, kind and gifted teacher, training many surgeons who have gone on to lead successful transplant programs.”

Emerson’s research has been published in more than 100 peer-reviewed publications and journals, including the New England Journal of Medicine, Circulation, Journal of the American College of Cardiology, Journal of Thoracic and Cardiovascular Surgery, The Annals of Thoracic Surgery, European Journal of Cardio-Thoracic Surgery, The Journal of Heart and Lung Transplantation, and Circulation: Heart Failure.

Emerson earned his undergraduate degree and medical degree from the University of Washington. He completed his general surgery residency at Georgetown University Hospital and completed fellowships in cardiothoracic surgery and thoracic transplantation at Cedars-Sinai. He joined the Cedars-Sinai faculty in 2019.

, whose research into sudden cardiac arrest has led to novel methods of predicting the usually fatal condition, has been promoted to vice dean and chief artificial intelligence health research officer at Cedars-Sinai.

Chugh was also honored recently with the Heart Rhythm Society’s 2025 Distinguished Scientist Award for clinical science. The award was presented April 26 during Heart Rhythm 2025 in San Diego. 

“This award recognizes Dr. Chugh’s dedication to understanding sudden cardiac arrest and preventing this deadly emergency,” said Eduardo Marbán, MD, PhD, executive director of the Smidt Heart Institute at Cedars-Sinai.

The Distinguished Scientist Award is given to an investigator who has made a lasting impact on patient care and the field of heart rhythm research. Chugh has dedicated his career to improving prediction and prevention of sudden cardiac arrest, a heart rhythm disorder that causes the heart to stop and often leads to instant death. He has published more than 275 scientific papers.

“I’m grateful to the Heart Rhythm Society for this recognition of our work and accept it on behalf of my colleagues and mentees at Cedars-Sinai,” said Chugh, the Pauline and Harold Price Chair in Cardiac Electrophysiology Research. “Our team is motivated to make a real impact on this deadly condition.”

According to the American Heart Association, more than 356,000 out-of-hospital cardiac arrests occur each year in the U.S. Nearly 90% of them are fatal.

Chugh’s team discovered a new method for identifying the best candidates for the implantable defibrillator, a lifesaving intervention. They also combined data from emergency responders, medical records and biological samples to predict imminent sudden cardiac arrest within hours to days of warning symptoms. Their work has improved identification of people at risk and led to the term “near-term prevention” of sudden cardiac arrest.

Chugh is also a leader in artificial intelligence research, which he has harnessed to improve prediction of sudden cardiac arrest.

In his new role as vice dean and chief artificial intelligence health research officer, Chugh will oversee the translation of AI research into clinical trials and patient care. He will lead the new Artificial Intelligence in Medicine Research Center (AIMRC), which will help departments and institutes incorporate AI into their research.

“Dr. Chugh is a foremost investigator in both heart rhythm and AI research,” said Jeffrey Golden, MD, executive vice dean for Research and Education at Cedars-Sinai. “His use of AI to assess the risk for sudden cardiac arrest has the potential to advance the field and save lives. We are eager for him to broaden his AI research experience to all areas of clinical care at Cedars-Sinai.”

In 2024, Chugh received the Distinguished Scientist Award for clinical science from the American College of Cardiology. He is a member of the American Society for Clinical Investigation and the Association of American Physicians, and is past president of the Association of University Cardiologists and the Cardiac Electrophysiology Society.

Coronary artery disease occurs when cholesterol deposits build up in the walls of the heart’s arteries, leading to formation of plaques that begin as areas of inflammation. When inflamed plaques grow large, they become prone to rupture, which can cause heart attack. Evolocumab is in a class of drugs called PCSK9 inhibitors that can dramatically reduce cholesterol.

“This discovery has important implications for understanding how evolocumab improves cardiovascular outcomes,” said Daniel S. Berman, MD, director of Cardiac Imaging in the Department of Cardiology in the Smidt Heart Institute at Cedars-Sinai and principal investigator of the study published in JACC: Cardiovascular Imaging.

Investigators administered evolocumab to 47 patients, all of whom had substantial buildup of noncalcified plaque in their coronary arteries. This type of plaque is regarded as higher risk than calcified plaque because it is softer and more likely to rupture and cause harm.

Before and 18 months after treatment with evolocumab, investigators studied inflammation in the coronary arteries using radioactive sodium fluoride and imaging with positron emission tomography (PET). They also used coronary computed tomography angiography (CCTA) coupled with a novel artificial intelligence quantitative method developed at Cedars-Sinai to measure changes in inflammation and plaque volumes in the coronary arteries.

The scans showed that, on average, plaque inflammation decreased and noncalcified plaque became smaller with evolocumab.

“Most attention has been placed on the cholesterol-lowering effects of PCSK9 inhibitors,” said Donghee Han, MD, a Cedars-Sinai internal medicine resident who is also a researcher in Berman’s laboratory and joint first author of the study. “Our findings demonstrate that reducing inflammation may be an important mechanism for reducing the risk of heart attack with these powerful drugs.”

Other Cedars-Sinai authors include Rebekah Park, Heidi Gransar, Mark Hyun, John D. Friedman, Sean W. Hayes, Louise E. J. Thomson, Alan C. Kwan, Prediman K. Shah, Sarah Wetzel, Chloe Findling, Piotr J. Slomka and Damini Dey. Other authors include joint first author Evangelos Tzolos, Matthew Budoff, Jacek Kwiecinski and co-senior author Balaji K.

“For very young children, use simple explanations when answering their questions,” Hedrick said. “With older children, you want to be honest and open, directly answering questions and using as simple language as possible.”

Playtime can help children express themselves and feel a sense of control. One example, Hedrick said, is focusing on the positive aspects of knowing fire safety.

“For children who haven’t lost their homes but are affected by the fires, involve them in age-appropriate fire drills,” she said. “Or allow other types of play to be related to the fire, because a lot of times it’s easier for kids to express their feelings through play than by outwardly saying, ‘I'm feeling scared.’”

Building simple forts with pillows, blankets and sheets can be a beneficial play activity for children of all ages—even some middle schoolers, Hedrick said.

“The parent can get inside the fort with them and talk about feelings, as the child may feel safer there,” she said.

It also can be helpful for parents to model how to express feelings.

“A parent could say something like, ‘I noticed I was feeling a little scared today; are you feeling scared?’ This gives their child a chance to talk about feelings of fear, anger, sadness,” she said.

Alternatively, when the child says they’re angry, sad or scared, parents should acknowledge those emotions.

“It’s important not to say, ‘You don't have to feel sad or scared or angry,’” Hedrick said. “It's better to say, ‘Of course, that’s how you’re feeling and it’s perfectly normal. At the same time, there are things we can be grateful for—let’s talk about some of those.’”

Tweens and teens especially may find journaling helpful, as well as art, physical activities and supportive connections with their peers.

“Reminders that there is hope, and that the family will get through this together, are important,” Hedrick said.

A former pack-a-day smoker, Shaw fits the profile of someone at risk for an aneurysm, even though he quit smoking more than two decades ago. That’s because current and former smokers are significantly more likely to develop an aortic aneurysm than nonsmokers. High blood pressure and family history are also risk factors.

The danger can go hidden because aneurysms don’t typically cause symptoms, although they can sometimes lead to indigestion, as was the case for Shaw, or more subtle issues. If an aneurysm keeps growing, it can burst—most people in whom this happens die from internal bleeding. That’s why vascular surgeons urge people like Shaw to get imaging tests that can help physicians find an aneurysm.

“If you have a family history of an aortic aneurysm, or you are a smoker, you should be screened,” said Cedars-Sinai vascular surgeon Elizabeth Chou, MD.

Chou explained that people at risk can see a primary care doctor, a cardiologist or a vascular surgeon for an imaging test such as an ultrasound or CT scan. Studies report that among people who get screened, about 3%-8% are diagnosed with abdominal aortic aneurysm.

An electrician and handyman who likes to stay active, Shaw had choices to make to prevent life-threatening rupture: minimally invasive catheter-based surgery or open surgery through an incision?

When Shaw met Chou, he learned his best option for his condition and lifestyle was an open surgery, where Chou and team would create an incision in the abdomen, sew a tube to the healthy parts of the aorta, and remove the aneurysm.

For people who have a smaller aortic aneurysm, a vascular surgeon will recommend an annual CT scan to see if it grows.

“Some aneurysms do not grow for many years,” said Chou, who is also assistant professor of Vascular Surgery in the Smidt Heart Institute at Cedars-Sinai. “Some people may never need surgery or any sort of repair, only routine monitoring.” She added that research is underway to help physicians understand why some aneurysms grow and some stay the same.

If an aneurysm reaches a certain size—about 5 ½ centimeters in men and 5 centimeters in women—a vascular surgeon typically recommends surgery.

Some patients may benefit from a minimally invasive surgery, during which a catheter is threaded through an incision in a patient’s groin until it reaches the aneurysm. The surgeon positions a tube in the area of the aneurysm and relines the aorta and aneurysm to divert blood flow into the relined aorta and away from the aneurysm. This option is usually recommended for patients who are older, frail, and generally wouldn’t recover well from an open surgery.  Some people also choose this option because they prefer a less invasive approach and are willing to undergo annual follow-ups to make sure the relining remains intact.

Shaw felt confident in Chou’s recommendation for an open surgery

“I live on a ranch,” he said. “I toss around bales of hay and 50-pound bags of horse feed. I need to be totally well. Anything other than a completely replaced artery was not acceptable because of my lifestyle.”

Chou said the most important part of the process is for patients to understand what the aneurysm is and how it affects their life.

“There are pros and cons to open surgery, minimally invasive surgery, and watching and waiting,” she said. “Our utmost priority is ensuring that each patient is comfortable with their decision. What we want people to know is that they need to be screened, and we will take the next steps together.”

After almost a week of recovery in the hospital and four weeks of recovery with light activity at home, Shaw returned to horseback riding on his ranch in Santa Maria, California.

“This could have ruptured at any time,” he said. “I was a walking time bomb. Now I’m totally healthy.”

Children with Duchenne typically lose the ability to walk by age 12 and die at a young age, commonly because their heart becomes so weak it can no longer pump blood.

“When we discovered he had Duchenne muscular dystrophy, I really felt like the sky had fallen down. I mean, that was my world,” Jayasuriya said from her home in Newport Beach, California, where she lives with her husband and Dusty.

Duchenne is caused by a mutation on the X chromosome and mostly affects boys. Jayasuriya was determined to find a potential treatment for her son and the approximately 20,000 other children diagnosed with Duchenne around the world each year.

Jayasuriya read a 2011 article in The Economist that described how Eduardo Marbán, MD, PhD, executive director of the Smidt Heart Institute at Cedars-Sinai, was studying how heart stem cells might repair heart damage. A light bulb went off. She requested a meeting with Marbán and the two forged a mission-filled friendship.

In 2013 Jayasuriya raised $150,000 through her organization, Coalition Duchenne, to fund preliminary research. Now 32, Dusty stands to potentially benefit from a cell therapy created from research Marbán has pursued for decades and that his mother helped fund.

The U.S. Food and Drug Administration (FDA) is currently evaluating deramiocel, a cell product that is based on Marbán’s discoveries. If approved, deramiocel would be the first treatment for the heart damage that often kills young people with Duchenne muscular dystrophy.

Children with Duchenne first show problems with walking or moving their arms. Their heart deterioration isn’t obvious until the heart is close to failing.

“The heart is turning into leather inside their chest,” Marbán said. “They're not aware of it until they're much older because the heart has some reserve, but it ends up being heart failure that accounts for most of the deaths from Duchenne.”

Marban is scheduled to discuss his work at a Feb. 25 FDA virtual workshop on cell therapies. The workshop is open to the public and attendees must register here. Marban's presentation is part of a four-scientist panel, “Cell Therapies for Niche Indications: Clinical Insights and Future Directions.”

The Research Begins 

More than 20 years ago, Marbán became interested in using pluripotent stem cells, which can turn into almost any cell in the body, to reprogram heart cells to generate an electrical pulse in people with abnormal heart rhythms—a biological pacemaker. However, given their propensity to migrate and create tumors, such stem cells were not realistically ready for clinical testing. Marbán and colleagues then turned their attention to isolating from the adult human heart a special type of cell capable of repairing damaged tissue.

“The dogma at the time was that once the heart is injured, it's permanent and it doesn't recover,” Marbán said.

In his laboratory, then at Johns Hopkins University, Marbán developed a technique, starting with a small human heart biopsy, to enable heart cells to self-assemble into microscopic clusters called cardiospheres. He and his team further cultured cardiospheres so that they would dissociate into cardiosphere-derived cells or CDCs. The CDCs could be grown in a laboratory and given back to the patient from whose heart they were taken.

When Marbán joined Cedars-Sinai in 2007 as the inaugural director of the Smidt Heart Institute, he began translating his basic work on CDCs into therapeutic studies in patients. Clinical trials showed heart attack patients who received infusions of their own CDCs into their hearts had some regrowth of healthy heart muscle. Curiously, additional research revealed it wasn’t the cells themselves that did the repair.

Ahmed Ibrahim, PhD, MPH, once a PhD student in Marbán’s lab who is now assistant professor of Cardiology at Cedars-Sinai, discovered that CDCs secrete tiny fat droplets called exosomes. These exosomes are full of molecules that support heart repair. This revelation meant that rather than biopsy a patient's heart, grow the cells and inject those cells into the same patient a month later, investigators could use donor hearts to prepare thousands of doses of CDCs that could be available “off the shelf.” Donor hearts are typically donated for transplantation but may be used for research if they cannot be used for a suitable recipient for technical reasons.

Duchenne and Heart Disease

Jayasuriya piqued Marbán’s interest in Duchenne heart disease. He began to study the effects of CDCs in laboratory mice with a genetic defect mirroring that in Duchenne patients. Working with Marbán, Smidt Heart Institute Assistant Professor Russell Rogers, PhD, discovered that CDCs worked well in Duchenne mice when given intravenously, leading to clinical trials in patients with Duchenne. The research verified CDCs could improve heart and muscle function in boys and young men with Duchenne.

The biotechnology company Capricor Therapeutics licensed Marbán’s technology and conducted additional clinical trials that led the company to apply for FDA approval of CDCs, now known as deramiocel, in December 2024. If deramiocel is approved, patients with Duchenne could receive an intravenous infusion of the therapy every three months.

“Our hope is that this therapy will meaningfully slow the progression of the disease and extend patient lives,” Marbán said.

Investigators in Marbán’s laboratory group are continuing to study what makes exosomes from CDCs potent.

“CDCs work by secreting tiny vesicles packed with genetic material,” Rogers said. “We are looking into the possibility that some of this genetic material may be effective when delivered on its own.”

For Dusty, who has lived longer than most people with Duchenne, the potential therapy is a chance to save his heart.   

“This is great news for older people with Duchenne like me,” he said. “This could make a true difference and impact on my life.”

Jayasuriya said the approval would be a game changer. She encourages parents of children with a rare disease like Duchenne not to give up hope.

“There may be something that works for another condition that can actually work for the condition your child has,” she said. “You just never know. There are no rules.”

“To see this level of investment in women’s heart health is remarkable,” said Arthur J. Ochoa, JD, senior vice president of Advancement and chief advancement officer at Cedars-Sinai. “Philanthropists like Erika Glazer are changing the face of healthcare and bringing advanced care to so many of our patients.”

Glazer’s journey into heart care began in 2013, when she established the Erika J. Glazer Chair in Women’s Heart Health. The funds generated by the chair’s endowment supported the work of Jennifer Van Eyk, PhD, an expert in the study of proteins whose research focuses on sex differences in heart disease. Van Eyk is director of Basic Science Research in the Barbra Streisand Women’s Heart Center in the Smidt Heart Institute at Cedars-Sinai, director of the Advanced Clinical Biosystems Institute and professor of Cardiology, Biomedical Sciences and Pathology and Laboratory Medicine.

“Science is an uncharted territory,” said Glazer. “I wanted to help ensure that women were not left behind when it comes to heart health and research.”

Glazer further widened her philanthropic focus in 2016 when she established the Erika J. Glazer Chair in Women’s Cardiovascular Health and Population Science, currently occupied by Susan Cheng, MD, MPH, MMSc, director of the Institute for Research on Healthy Aging and division director of Population Health Sciences in the Smidt Heart Institute at Cedars-Sinai.

Then in 2023, Glazer funded her third chair at Cedars-Sinai—the Erika J. Glazer Chair in Women’s Cardiovascular Research, Education and Innovation. The inaugural chairholder is Janet Wei, MD, FACC, associate medical director of Cedars-Sinai’s Biomedical Imaging Research Institute, director of the Cardiovascular Disease Fellowship program in the Smidt Heart Institute, and associate professor of Cardiology and Biomedical Sciences at Cedars-Sinai. 

Righting a Wrong

Glazer’s philanthropic inspiration was sparked by her growing awareness of the underrepresentation of women in heart research, coupled with the need for greater gender equity in the United States.

“Women’s heart disease impacts everyone, in that all of us have a mother, a sister, a daughter, and/or a wife,” said Glazer, who at age 16 spent time interning at Cedars-Sinai—known then as Cedars of Lebanon—in the cardiology laboratories. “We must do more, we must do better, and we must do it now.”

While she considered a career in healthcare, Glazer opted to join her father, Guilford Glazer, in real estate development.

Glazer has made a name for herself in the male-dominated fields of construction and sports. A successful equity investor, she currently is a co-owner of the NBA’s Golden State Warriors.

“If it’s your passion, nothing should stand in your way,” Glazer said.

In addition to aiding Cedars-Sinai’s mission to attract and retain exceptional investigators, in 2016, Glazer also pledged $7.2 million for the Erika J. Glazer Women’s Heart Research Initiative at the Barbra Streisand Women’s Heart Center to support investigations into heart failure with preserved ejection fraction (HFpEF), a type of heart failure that primarily affects women.

“We are increasingly thankful to Erika Glazer—our colleague, our friend and our partner—for helping us to uncover the secrets of women’s heart health and disease,” said C. Noel Bairey Merz, MD, FACC, director of the Barbra Streisand Women’s Heart Center, and the Irwin and Sheila Allen Chair in Women’s Heart Research. “She is a doer, and she is changing the face of heart disease for women and men.”

A Champion for Women

Wei, the newest chairholder supported by Glazer, is awed by the woman behind its creation.

“I’m honored to join an inspiring group of women leaders who have benefited from the vision and generosity of Erika Glazer,” Wei said. “She is a champion for women’s heart health and is providing opportunities for my colleagues and me to advance the research, education and innovations that will save lives.”

People living with tricuspid valve disease are gaining more treatment options, driven by research from Cedars-Sinai investigators and collaborators at other leading medical institutions.

Traditionally, cardiothoracic surgeons have repaired or replaced the tricuspid valve during open-heart surgery and only when absolutely necessary; such surgeries are complex and risky. Now, an increasing number of studies show that cardiac interventionalists can successfully use minimally invasive catheter-based techniques. Catheter-based procedures offer an alternative for patients who are not candidates for open-heart surgery.

Raj Makkar, MD, vice president of Cardiovascular Innovation and Intervention and the inaugural director of the Karsh Division of Interventional Cardiology in the Smidt Heart Institute at Cedars-Sinai, and his team of experts treat more than 10,000 patients every year. Makkar sat down with the Cedars-Sinai Newsroom to explain advances for patients with tricuspid valve disease.

What is tricuspid regurgitation, and who does it affect?

Tricuspid regurgitation is a condition where the tricuspid valve fails to close properly, allowing blood to flow backward into the right atrium. Studies estimate that severe regurgitation occurs in up to 4% of individuals 75 and older and is often linked with conditions like heart failure, atrial fibrillation or pulmonary hypertension. Women are more frequently affected, and because the condition often develops slowly, many patients are diagnosed at advanced stages when symptoms like swelling, fatigue and breathlessness impact them.

How has treatment for tricuspid valve disease evolved?

For decades, tricuspid regurgitation was largely overlooked, often addressed only during surgeries for other heart valves. Today, advances in minimally invasive treatments like transcatheter edge-to-edge repair (TEER) and transcatheter tricuspid valve replacement (TTVR) are providing new hope. These innovative procedures offer safe and effective options for high-risk patients who previously had limited or no treatment alternatives, focusing on enhancing quality of life.

Cedars-Sinai investigators, in collaboration with colleagues from other leading institutions, recently conducted a clinical trial involving patients with severe tricuspid regurgitation. The study, published in the New England Journal of Medicine, found that patients who underwent catheter-based tricuspid valve replacement combined with medical therapy reported significantly greater improvements in symptoms and quality of life compared with those receiving medical therapy alone. These findings mark a significant step forward in the treatment of this historically neglected condition.

When might a minimally invasive procedure be the best approach?

Minimally invasive procedures for the tricuspid valve are generally the only option for older or frail patients, who are unable to withstand traditional open-heart surgery. A TEER procedure, which inserts clips in the valve to reduce leakage, works well for many, but is less effective for those with complex valve anatomy. In such cases, TTVR, which replaces the valve entirely, may be a better option.

How do you discuss options with patients?

At the Smidt Heart Institute, physicians discuss the case as a group and review imaging findings and other information to determine whether a transcatheter procedure, minimally invasive surgery, medical intervention alone or a clinical trial is best for each patient.

Selecting the right treatment involves careful evaluation of the patient’s health, anatomy and goals. We prioritize improving quality of life, particularly for patients experiencing severe fatigue and breathlessness.

Raphael Louise Wasserman, who was born with a serious heart condition, has had more medical interventions in the first months of his life than some adults will ever have. But now, he and his family are looking forward to a life filled with more birthday celebrations than doctors’ appointments.  

Raphael and his twin sister, Antonia, who was born without a heart condition, celebrated their birthdays on Valentine’s Day, Feb. 14, at Cedars-Sinai Guerin Children’s. They were joined by their mothers, friends and family as well as the nurses, physicians and staff members who took care of them.

“Heart defects are the most common birth defect,” said Richard Kim, MD, director of Pediatric and Congenital Heart Surgery and surgical director of the Guerin Family Congenital Heart Program in the Smidt Heart Institute and Guerin Children’s. “Thankfully, we can now intervene early so babies and young children can get better quickly.”

Mothers Claire and Ashley credit the close attention their children received with getting Raphael the care he needed. Soon after he was born, a nurse noticed Raphael had a heart murmur. A couple of days later, he had open-heart surgery to fix the malformations that were preventing his heart from pumping blood properly.

But one issue remained: One of Raphael’s heart blood vessels had become so narrow it was affecting his heart. In August, Raphael became one of the first children to receive the first stent specifically designed for babies and children. The stent was studied at Cedars-Sinai, and Evan Zahn, MD, director of the Pediatric Congenital Heart Program at Guerin Children’s and the Smidt Heart Institute, helped develop it. The stent’s design allowed it to be placed during a minimally invasive procedure rather than through an open-heart surgery.

“It was so rewarding to care for Raphael, who had especially complicated structural heart defects,” said fetal and pediatric cardiologist Myriam Almeida-Jones, MD. “Thanks to our team-based approach and our latest advances, we were able to improve Raphael’s heart so he and his family can have many more milestones to celebrate.”

That’s what she’s been doing since she was 22, when she was diagnosed with dilated cardiomyopathy, a rare disease that causes the heart muscle to weaken and, eventually, stop pumping blood.

After college graduation, Epps-Manuel began her career in special education. She grew up with a brother with special needs, and Epps-Manuel believed she had found her calling. But one day in 2010, during her first job as a teaching assistant, she came home feeling like she had just run a marathon. She couldn’t catch her breath. An emergency physician discovered her heart was enlarged, and the next day, a cardiologist diagnosed Epps-Manuel with dilated cardiomyopathy.

Just three years earlier, the former intramural college volleyball player had given birth to a healthy boy, and she had never had health issues. No one in her family was known to have a heart condition.

Epps-Manuel’s type of dilated cardiomyopathy is idiopathic, meaning the cause is unknown.

“It was very hard mentally,” she said. “I started having issues with palpitations and had to start wearing an external defibrillator. It was just one thing after another.”

To give herself more flexibility, Epps-Manuel left her elementary school job, moved in with her parents and started a ministry and service center for people with cognitive disabilities.

A few years after she was diagnosed, surgeons at Baylor University Medical Center in Texas implanted a left ventricular assist device (LVAD) to help Epps-Manuel’s heart pump blood. Less than two years later, she received a second LVAD after the first one caused a major blood clot in the cannula of the device’s pump.

In December 2014, Epps-Manuel received a long-awaited heart transplant in Texas, which was followed by difficulties. Medications she took to keep her body from rejecting her new heart so severely injured a kidney that she had to undergo a kidney transplant in 2022. Ten years after the heart transplant, her heart also started to fail. That’s when her Texas doctors referred her to the Smidt Heart Institute at Cedars-Sinai. Tyler Gunn, MD, assistant professor of Cardiac Surgery, led the team of physicians, nurses and operating room staff who performed the transplant.

“When I first met Destany in April 2024 she was very sick, but she was physically fit and had a lot of life ahead of her,” Gunn said.

Epps-Manuel’s case pushed the limits of what surgeons can do.

“With each additional redo surgery, different parts of the heart, tissues and bone fuse together and it becomes much more technically challenging to operate,” Gunn said. “These surgical considerations are why centers from across the nation refer their most difficult cases to Cedars-Sinai.”

Although Epps-Manuel has spent much of her adult life facing life-or-death situations, waiting for her second heart transplant made her feel especially hopeless. She credits the support program led by Rebecca Hedrick, MD, director of Consultation Liaison Services in the Department of Psychiatry and Behavioral Neurosciences, with helping her through her sickest period. The program taught her coping tactics such meditation and helped her use virtual reality to calm her mind. 

“You have to feel your feelings, but you can't stay there,” she said. “You have to have a mindset to fight.”

Epps-Manuel’s second heart transplant took place in October 2024 during a nine-hour operation at the Smidt Heart Institute. A life-support machine called cardiopulmonary bypass temporarily did the work of Epps-Manuel’s heart and lungs. It took surgeons two hours to carefully dissect the bands of scar tissue around the old heart and remove it, a process that typically takes 30 minutes.

Another challenge the Smidt Heart Institute faced was that Epps-Manuel had developed antibodies to the first transplant, so there was a high risk that any future donor heart would be quickly rejected.

Jon Kobashigawa, MD, director of the Heart Transplant Program at Cedars-Sinai and a world expert in preventing and treating organ rejection, managed Epps-Manuel’s care pre- and post- transplant. He created an aggressive immunotherapy plan to stop her body from rejecting the new heart.

Epps-Manuel and her mother lived in Los Angeles for months while she waited for her transplant and recovered afterward. She missed being able to tour colleges with her son, but she is now healthy enough to travel back and forth between her home in Cedar Hill, Texas, and Cedars-Sinai, where she continues to receive desensitization therapy for donor antibodies. She’s excited to volunteer with her ministry again and watch her son compete in senior-year football and track.

“Destany has an incredible, upbeat attitude, which contributes to her recovery,” Kobashigawa said. “She is a joy to care for and continues to inspire our collective team.”

People with metabolic disease who have three or more cardiovascular risk factors—such as high blood sugar, low levels of HDL (good) cholesterol and high blood pressure—often develop cardiovascular disease and kidney disease. People who have two or more of these diseases or are at risk of developing them are described by medical experts as having cardiovascular-kidney-metabolic (CKM) syndrome.

“We need additional research to understand the biologic processes that cause men and women to experience disease differently,” said Susan Cheng, MD, MMSc, MPH, the Erika J. Glazer Chair in Women’s Cardiovascular Health and Population Science in the Department of Cardiology in the Smidt Heart Institute, and co-corresponding author of the study. “The more we know, the better we’ll be able to prevent women from dying from less severe forms of CKM syndrome.” 

The number of people with CKM syndrome increased steadily from 1988 to 2018, according to investigators. They also found stage 3 disease occurred more among men (from 18.9% to 22.4%) as compared with women (13.9% to 15.2%). Although women were less likely to develop stage 3 disease, they were more likely to die during any stage of the disease.

That’s true for people experiencing the trauma of devastation and loss firsthand, as well as those following the news from a distance, said Rabbi Jason Weiner, PhD, senior rabbi at Cedars-Sinai and director of the Spiritual Care Department.

“This tragedy reminds us all of our vulnerability,” he said.

Itai Danovitch, MD, chair of the medical center’s Department of Psychiatry and Behavioral Neurosciences, said feeling distress and anxiety right now is normal, as is feeling numb or disconnected from emotions.

“There is no one-size-fits-all response to the challenges we’re facing, and adapting to stress can take time, but it helps to pinpoint specific sources of worry,” Danovitch said. “Is there nervousness about the safety of loved ones or a home? Is it the long-term impact on the community or uncertainty about air quality? Knowing this can help manage anxiety in a constructive way.”

Among anxiety management tactics are maintaining daily routines and self-care while staying connected with supportive people, getting adequate rest and exercise, and practicing relaxation or meditation exercises.  

“It also can help to make sure you’re getting information from trustworthy sources to help avoid unnecessary fear,” Danovitch said. “Plan ahead for potential future evacuations and manage exposure to news and social media.”

Is It Post-Traumatic Stress Disorder?

Negative thoughts, sleep or concentration problems, social withdrawal or intensified and persistent symptoms of despair that interfere with daily functioning could signal post-traumatic stress disorder (PTSD).

“A therapist who specializes in trauma treatment, along with medications and participating in support groups and psychotherapy, can be beneficial,” Danovitch said. “Some people may develop PTSD and others won't, but all emotional responses deserve care and attention.”

The National Center for PTSD can provide guidance for immediate coping strategies and long-term recovery.

Feeling Seen and Heard

Cedars-Sinai Cancer Center Chaplain Carrie Kohler, MPhil, BCC, can personally relate to hospital patients and staff struggling with grief and uncertainty. She navigated those same complex emotions after evacuating her home during the wildfires.

“Some people are grappling with survivor’s guilt or a sense of helplessness as they try to support loved ones,” Kohler said. “For others, there are practical and logistical questions—how to file an insurance claim or get transportation to a Disaster Recovery Center. Social disparities, such as language barriers, physical disabilities or compromised health, can make already difficult tasks more challenging. It can all feel very overwhelming.”

Kohler said listening and validating experiences is critical in providing support.

“Comfort and hope are created when people feel seen and heard, and that can be simply sitting with someone in their pain without rushing to fix it,” she said. “Hope isn’t about erasing pain or pretending everything will be fine; it’s about making space for all emotions and respecting individual experiences.”

Empathy From Afar

Those who live miles away may also feel distraught. Danovitch said that’s human nature—and it may be especially true for people who once lived in Los Angeles, because the fires conjure nostalgia as well as loss.

“Former Angelenos often have deep relationships, memories and connections to the area,” he said. “Seeing those threatened can heighten feelings of longing and attachment.”

Kohler agreed. “It might even reignite memories of your own past challenges in L.A., blending past and present grief,” she said. “For people without a direct connection, the fires may evoke a generalized empathy or compassion. These are normal emotions and feelings.”

Helping Children

For parents of kids who have experienced the fires, listening is key, said Suzanne Silverstein, MA, founding director of Cedars-Sinai Share & Care and a registered art therapist.

“Hear what they’re saying,” Silverstein said. “Instead of talking at them, validate their feelings by acknowledging that it’s scary, hard or sad. Reassure them that they are OK as a family and will get through this together.”

Art for young children can be a beneficial coping mechanism: Children can draw things they miss, or items they would have gotten out of their home if they’d had the chance. Very young children may be better able to express feelings through play—using dolls or stuffed animals to act out scenarios and discuss emotions, or building forts with sheets and pillows to create a “safe space.”

“When adults can provide a safe emotional space for the child to take the lead in creative play, children will naturally work through difficult emotions without having to verbalize their feelings directly,” said Rebecca Hedrick, MD, child and adolescent psychiatrist at Cedars-Sinai. “It helps them feel some control and be able to process grief.

“Older kids may benefit from a daily ritual of saying five things that they’re sad about, five things they’re worried or angry about, five things they’re grateful for, and five things they’re looking forward to.”

The Path Forward

Patience, compassion, and faith in a better future are values to uphold in this time of crisis, the experts agreed.

“Take time to stop and mourn, and then address things one day at a time, one minute at a time,” Weiner said. “We shouldn’t try to do it all on our own—we need community now more than ever. I’ve been very moved by our community’s resilience.”

Cedars-Sinai Christian Chaplain the Rev. Peggy Kelley said she often has witnessed that “out of chaos comes creation,” and added, “This moment in time will bring healing restoration, new depths of compassion, profound lessons and growth.”

Kohler noted that spirituality can serve as an anchor to help make sense of what can feel senseless.

“Faith doesn’t erase pain,” Kohler said, “but it can provide a way to hold that pain while moving toward healing. We’re all in this together, and whether it’s in shared grief, acts of kindness, or the effort to rebuild, this experience has deepened my appreciation for community. By holding space for grief and recovery, we transform collective trauma into collective renewal.”

Heart failure occurs when the heart cannot pump enough blood and oxygen to support the body’s other organs. This condition can cause fatigue, shortness of breath, swelling, other debilitating symptoms and shorten life. Heart attacks, which damage the heart muscle, are among the most common causes.

The new study, published in European Heart Journal, analyzed the effect of administering a small molecule known as PR-364 to adult male laboratory mice that endured a heart attack, also known as myocardial infarction. Data showed this treatment preserved the heart’s pumping power and mitigated the progression of heart failure in the treated mice versus mice that were not treated.

To uncover why PR-364 had such a profound impact, the investigators performed additional laboratory experiments using mouse tissue and cells along with human cardiomyocytes, the cells that make up the heart muscle. They also analyzed changes in proteins in mice that had received the drug.

The data indicated that PR-364 enhanced the functioning of mitochondria, the small structures in cells that generate energy to power biochemical reactions. Healthy mitochondria are critical drivers of the processes that protect and repair the heart and other muscles. PR-364 altered the mitochondria in several beneficial ways:

• By increasing mitophagy, the process by which the mitochondria that have been damaged by a heart attack are destroyed and cleared from the body, which aids repair of the heart muscle
• By increasing production of new mitochondria
• By improving the overall functioning of the mitochondria

“Taken together, these effects suggest how PR-364 helped prevent the development of heart failure after heart attacks in laboratory mice,” said Jennifer Van Eyk, PhD, professor of Cardiology in the Smidt Heart Institute at Cedars-Sinai and director of the Advanced Clinical Biosystems Institute at Cedars-Sinai. “While our data does not prove that PR-364 would have this impact on patients, it points to a unique, promising path toward developing heart failure strategies for survivors of heart attacks.” Van Eyk was co-corresponding author of the study along with Roberta Gottlieb, MD, formerly of Cedars-Sinai.

Van Eyk said the next steps in this research are threefold: to study whether a second-generation version of PR-364 may be more effective, to determine whether there are differences in responses based on gender and to delve more deeply into how PR-364 works.

Eduardo Marbán, MD, PhD, executive director of the Smidt Heart Institute at Cedars-Sinai, said the new study’s findings are especially important, given that more people than ever are surviving heart attacks.

“Although several drugs have reduced injury in mice after a heart attack, almost all are preventive: They must be given beforehand. Unfortunately, no one has a crystal ball predicting just when a heart attack will occur in real life,” Marbán said. “What is particularly noteworthy here is the fact that improved recovery was seen when PR-364 was administered a full two hours after the heart attack, improving the likelihood of successful translation to patients.”

The medical center has issued more than $250,000 in emergency grants to nonprofit organizations assisting residents, workers and business owners affected by the disaster, as well as supporting first responders on the front lines.

Nine organizations so far have received grants, with amounts ranging from $15,000 to $50,000, to help address the community’s relief and recovery efforts.

“Whether it’s direct aid or volunteer efforts, Cedars-Sinai will continue to leverage all of its resources to help rebuild and strengthen our community,” said Erin Jackson-Ward, DrPH, executive director of Grantmaking and Social Impact at Cedars-Sinai. “So many of our community members are facing tremendous loss and uncertainty, and we feel a deep responsibility to support our beloved city during this challenging time." 

Among the causes receiving grants are the Los Angeles Fire Department Wildfire Emergency Fund, United Way of Greater Los Angeles Wildfire Response Fund, the California Community Foundation Wildfire Recovery Fund, and the Pasadena Community Foundation’s Eaton Canyon Fire Relief and Recovery Fund.

The Jewish Federation Los Angeles, Food Access Los Angeles, Inclusive Action for the City, the Institute of Popular Education of Southern California Essential Workers Fund and the YMCA of Metropolitan Los Angeles Community Response Fund also received grants to help pay for immediate response needs. Funding to the YMCA, for example, will help provide free daycare for children of first responders, essential workers and displaced or evacuated families. Other grants are focused on providing mental health services to those impacted as well as direct assistance to low-income workers and those displaced by the fires.

Cedars-Sinai also is making in-kind donations, including its distribution of more than 13,000 N95 masks and the issuance of personal protective equipment, such as goggles, respirators and coveralls. Additionally, Cedars-Sinai is focused on offering resources and support to its employees across the health system through the Emergency Employee Fire Relief Fund.

“We recognize that the road to recovery will be long, but Cedars-Sinai is committed to standing shoulder-to-shoulder with the people of Los Angeles,” said Arthur J. Ochoa, JD, senior vice president of Advancement and chief advancement officer for Cedars-Sinai. “As Angelenos grapple with the aftermath of these devastating wildfires, we want the message from our institution to be clear: we are in this together, and we will emerge from this crisis stronger than before.”

“Rather than have this hanging over us while thinking of rebuilding, I decided I wanted to be operating at an optimum physical level,” Booher, 45, said. “My husband and I looked at each other and said, ‘This is tragic, but it doesn’t change the immediate plan. We’ll move on to the next step.’”

Booher and husband, Steve, along with their three greyhounds, evacuated their home on Jan. 7. He didn’t have time to pack the collection of comic books he has written. The next day, they learned the house was gone. By Jan. 9, Booher was at the Smidt Heart Institute at Cedars-Sinai for surgery to repair one of his heart’s valves.  

A few months prior, Booher had been diagnosed with mitral valve regurgitation, a condition in which the heart’s mitral valve doesn’t close as it should. Mitral valve regurgitation can cause heart failure, strokes and even sudden death, but it often goes unnoticed because symptoms are subtle. Booher’s fatigue, which he chalked up to his active lifestyle, was one such overlooked sign.

Joanna Chikwe, MD, chair of the Department of Cardiac Surgery at Cedars-Sinai, spent last Wednesday reassuring patients who were watching the Sunset fire from the hospital’s windows that they were in the safest place to be.

“I called patients already scheduled to have open-heart surgery to see what they wanted,” she said. “When I saw David’s address I thought, ‘He’ll never want to proceed. He must be overwhelmed.’ But I was astonished and inspired by his resolve. He told me, ‘Let’s fix my heart so I can rebuild my life.’”

Chikwe repaired the faulty heart valve through a tiny incision with the help of a robot, and Booher, recuperating at a friend’s home a few days later, already feels transformed.

“It boggles my mind that they went into my heart, repaired my valve, and now I feel so healthy,” he said. “The change has been remarkable. I feel like my heart is working efficiently. I feel clearheaded.”

Booher is coming to terms with not being able to go back to a community he loves. Altadena is a special place for him, a mix of architecture, mom-and-pop shops and tight-knit neighbors. He and his husband plan to spend time at their cabin in Big Bear where he’ll continue to write.

“Emotionally, it is starting to sink in,” he said. “When I was in the hospital, I was recovering, so I didn’t have the chance to internalize what happened. I have an incredible support system as I am working through my grief of losing everything. I’m grateful our dogs are safe, we are safe and have a place to stay. And I’m grateful for a healthy heart. That’s what we have to hold on to.”

And as people in Los Angeles County spend more time indoors in the aftermath of widespread wildfires—avoiding smoke-filled air, keeping out of the way of emergency responders and sheltering in place—they should be prepared to treat some of those injuries on their own, when possible, said Gregory Jones, RN, injury prevention and outreach coordinator for the Cedars-Sinai Trauma Program.

“It’s good to have basic knowledge—and a first-aid kit—ahead of time,” Jones said. “Unfortunately, many people don’t think about it until it’s too late. You want to prevent being in a situation in which you are completely unprepared.”

When Jones—whose job is to be prepared for emergencies and trauma—was recently faced with looming evacuation orders during an approaching wildfire, he was reminded first-hand that proper planning and preparation take time, focus and even practice.

“I talk every day about the importance of being prepared, and yet, as we packed to evacuate, I still needed to pause and recenter myself,” he said. “Be as ready as you can for an emergency, and that includes at-home first-aid planning. Know what to do to help yourself or someone else.”

The Cedars-Sinai Newsroom spoke with Jones about ways to prepare for and treat injuries at home, especially when it may be difficult to leave the house for immediate care.

What is the first thing a person should do if they’ve been injured at home or are looking to help someone who has?

Assess the situation and take a deep breath. Basic knowledge of first-aid practices will help. For example, for a bad cut, you should apply pressure to stop bleeding. If someone else is injured, consider whether it’s safe for you to help, or whether there is a chance you also could get injured. Also think, “Is this bigger than what I can do at home?” If that’s the case, make every effort to seek medical help. If there’s a life-threatening emergency, call 911. But when it comes to immediate care for cuts, burns, sprains and fractures, even a little knowledge goes a long way. So does a first-aid kit.

What should be in a first-aid kit?

A basic first-aid kit should have bandages, gauze, medical tape and an antibiotic cream. To supplement that, you could include varying sizes of bandages, extra gauze and a small pair of scissors. If you have young children, add fun adhesive bandages or stickers. SpongeBob SquarePants is a very good distraction from an injury.

What is the best way to treat a bad cut?

First, if there’s glass on the floor and you’re barefoot, grab slippers. Wash the cut with soap and water and apply direct pressure to stop bleeding. Dress the wound with antibiotic cream and cover it with a sterile bandage or gauze. Cleaning and covering the wound are critical to prevent infection. If you don’t have a bandage, use a clean kitchen towel or a T-shirt. Even a sock would work; in an emergency, you may need to improvise and use whatever is handy.

In the case of an amputation—you’ve lopped off the end of a finger chopping vegetables—try not to panic. Put the amputated part in a plastic bag filled with water and ice. This ice bath may allow it to be reattached when you are able to access medical care.

A word about pets: If your pet gets a cut, clean the wound with soap and water, use antibiotic cream and try to bandage the area until you can get them to a vet.

What is the best way to care for a burn?

For a mild burn—you touched a hot pan, for example—the first thing to do is cool down the burned area. Run cool water over it, and maybe apply ice, but never put ice directly on the skin. If you do use ice, put it in a plastic bag, wrap a towel around the bag, and only use it for a minute or two at a time. You want to cool the skin, not freeze it. Cover the burn with gauze or a sterile bandage.

If the burn is more severe—there’s a blister or broken skin—clean the area with soap and water, and then apply antibiotic cream and dress it with a sterile bandage. Don’t break the blister; it provides a protective barrier and helps prevent infection.

What should a person do if there’s a sprain or fracture?

For sprains, apply ice to help reduce swelling. You may want to alternate between ice and heat. If you think you have a broken bone and you cannot get medical help right away, splint the limb to immobilize it. You can splint a leg with household items such as a broom and mop. Place one on either side of the leg to help immobilize it and use medical tape to secure the splints. To splint an arm or wrist, consider using a book on either side of the arm, and use a kitchen towel or even a sock to hold the limb in place. Remember, improvisation is key.

Is there anything else to remember when it comes to emergency planning or at-home care for injuries?

Two things: Take a basic first-aid or a Stop the Bleed class. Most communities offer them. Also, remember to give yourself grace. My career is in trauma and emergency medicine, and even still, as my family prepared to evacuate last week, it was a tense time and a little chaotic. I had to remind myself of the importance of grace.

That’s because the weather data does not measure many dangerous pollutants circulating in the air from smoke and wind, said pulmonologist Jeremy Falk, MD, associate professor of Medicine at Cedars-Sinai.

“People may think, ‘Well, I don’t see or smell smoke anymore, and it looks sunny like it normally does in Southern California,’ and be lulled into thinking everything is fine,” Falk said. “But much of what can harm us in situations like this doesn’t have an odor. The Air Quality Index system was developed for everyday pollution, and not necessarily to warn us about particles that are not typically in the air because of wildfires.”

Falk, along with Irina Dralyuk, MD, a Cedars-Sinai Guerin Children’s pulmonologist, and Daryl Banta, MD, pulmonologist and medical director of Pulmonology and Critical Care at Huntington Health, an affiliate of Cedars-Sinai, said it’s best to err on the side of caution and stay as safe as possible during periods of bad air quality—which will be around as long as the fires continue to burn.

About the Air Quality Index

An Air Quality Index level of 101-150 indicates that people in sensitive groups (such as those with lung disease, severe allergies or heart disease) could experience sore throats, wheezing or difficulty breathing. A level of 151-200 means even those without chronic breathing problems could experience health effects.

Still, the Air Quality Index can be deceiving, Falk said.

“Homes and buildings are full of all kinds of materials that are toxic when burned—plastics, oil products, metals—and the Air Quality Index does not pick up on that. Another limitation is in the unpredictable, shifting winds. You don't know if the air quality data that you're viewing is up to date. What may be an ‘acceptable’ level of air pollution one minute may be a very different level half an hour later. It's the unknown that makes this situation so dangerous.”

The South Coast Air Quality Management District is a good resource to check updated air quality in your area.

Benefits of Wearing a Mask

“What makes the air pollution associated with fires so dangerous is that the particles that seem to do the most damage are much smaller than even the microscopic droplets we saw with COVID-19,” Falk said. “Because the particles are so tiny, they can fit between the fibers of a simple paper mask or cloth mask and get far down into our airways, causing damage.”

The best masks to protect the lungs from microscopic particles found in dust, smoke, smog and particulate matter are N95 masks that can filter out really small particles, down to the 2.5-micron level. However, if KN95 masks are more readily available, they also are acceptable.

Banta advised wearers to make sure that their masks fit properly. 

“If there is any leak around the mask because of a beard or incorrect size, you may be exposing yourself to unhealthy air or smoke,” he said.

Safety Outside and Inside

“The longer you're outside breathing air that we know is not safe, the more you’re putting yourself at high risk,” Falk said. “While the fires are still happening, any exercise that could be moved to an indoor space is preferable. If you really do need to be outside for any reason, wearing the N95 mask is the best approach.”

When inside, Banta said, close windows, make sure any cracks are sealed and that there’s a good air filtration system. Check that any air conditioner is recirculating air that is in the structure and not pulling in air from the outside.  

“If there is significant smoke, ash or dust inside, wear masks indoors,” he said. 

Most modern cars also have a recirculating option, although drivers should check to make sure the automobile’s air filters have been changed recently.  

Parents should keep an eye on children who have a cough, wheezing, noisy breathing, chest tightness or pain, increased rate of breathing or increased heart rate, shortness of breath, retractions, labored breathing, gasping for air, throat irritation, hoarse voice, confusion, dizziness, or mental changes.

“It’s advisable for children of all ages to wear an N95 or KN95 mask when outside,” Dralyuk said. “Also, avoid outdoor sports or events, and evacuate the area if your child is having symptoms or the air quality is very poor, or if your child has risk factors for respiratory issues.”

If children have respiratory issues, make sure they take all scheduled medications as prescribed, and have rescue inhalers at home. Also, check expiration dates and number of puffs left, and get refills as necessary.

Watch for Symptoms

Direct, prolonged smoke inhalation or exposure is very dangerous.

“If you have severe symptoms, such as severe cough, shortness of breath, chest pain, dizziness or confusion after smoke exposure, seek immediate medical attention,” Banta said.

Milder symptoms can include irritated or watery eyes, runny nose, scratchy throat, wheezing, headache, dry eyes, phlegm or irritated sinuses. Older people and very young children can be more susceptible to these effects, as well as people who have preexisting lung or heart problems.

For people with chronic medical conditions, exposure to smoke and unhealthy air could potentially increase the risk for stroke, heart attacks and lung conditions. People exposed to prolonged amounts of particulate matter also may be at increased risk for lung cancer.

“If the air outside is bad to breathe, do what you can to not breathe it,” Falk said. “There’s nothing high tech about it. Just use common sense—that’s going to be our best way out of this.”

Wildfires across Los Angeles County have forced hundreds of thousands of people to flee their homes, leaving many without critical medications.

But patients can access vital medications using a variety of resources, according to Cedars-Sinai pharmacists.

“There are options for those in need of medications during all types of natural disasters,” said Rita Shane, PharmD, vice president and chief pharmacy officer at Cedars-Sinai.

Shane, alongside Vipul Patel, PharmD, executive director of Pharmacy and Oncology Services; Douglas Malcolm, PharmD, associate director of Ambulatory Pharmacy; and Rachel Vaystub, PharmD, manager of Pharmacy Services, offered advice for navigating medication access during a disaster.  

How can patients refill medications without access to their prescriptions or their regular pharmacy?

Patients have a few options. If they use a chain pharmacy, they can go to any other location, which will be able to access their medication records and provide refills. Or they can visit a local pharmacy, explain their situation, and the pharmacy might be able to determine the patient’s medications by checking with the patient’s insurance company.

Patients can call their insurance provider to get their medication list and ask for a recommended pharmacy. Or they can contact their medical provider and get their prescriptions sent to another pharmacy. Online tools like RxOpen track which pharmacies have remained open during emergencies.

Will pharmacies refill prescriptions early?

Pharmacies can—in good faith—provide a reasonable supply of medications without a prescription during a federal, state or local emergency. Under their professional judgment, pharmacists can refill prescriptions if failing to do so could interrupt ongoing care or create a significant, adverse impact on a patient’s wellbeing. The pharmacist will need to contact the patient’s physician as soon as possible to explain what was provided.

Do patients need to find pharmacies covered by their insurance provider?

Patients can go to any pharmacy in an emergency, especially in a declared state of emergency. Out-of-network pharmacies might cost more up front, but patients might be able to submit a claim to their insurer for reimbursement. Patients should call their insurance company to determine which pharmacy they recommend and whether a reimbursement will be provided.

What should patients do if they are uninsured?

The federal government has activated the Emergency Prescription Assistance Program for specific zip codes in California to help uninsured residents replace prescription medications and certain medical equipment lost or damaged during the wildfires. Call the program’s hotline at (855) 793-7470 to find out if you are eligible and to register. Visit the program’s website to review a list of participating pharmacies. Free clinics also might be able to help with critical medications, and certain local pharmacies might be willing to waive payment during emergencies.

Can patients get controlled substances without a prescription in an emergency?

Controlled substances would be very difficult to access without any proof of prescription. Having a medication list or information from insurance companies helps pharmacies when these medications are needed during emergencies/disasters. Strict regulations require additional steps and may result in delays.

What else should patients know?

For self-administered injectables, appropriate storage, and access to supplies like needles and syringes are major considerations. Many of these medications require refrigeration, but some can remain at room temperature. It is best to consult a pharmacist about how long the medication will last outside a fridge. Local pharmacies can also provide supplies in emergency situations.

“Los pacientes con enfermedades de las vías respiratorias, como fibrosis pulmonar, EPOC y asma, pueden experimentar un empeoramiento de los síntomas debido a la exposición a la mala calidad del aire por los contaminantes de los incendios forestales”, dijo Isabel F. Pedraza, MD, profesora asistente de Medicina y directora de la Unidad de Cuidados Intensivos Médicos en el Cedars-Sinai. “Queremos asegurarnos de que nuestros pacientes tienen acceso a la atención cuando más lo necesitan.”

Los pacientes de neumología, dijo Pedraza, deben asegurarse de tomar sus inhaladores según lo prescrito, así como cualquier otro medicamento “controlador” que contenga un esteroide inhalado.

“Tanto los inhaladores como los medicamentos de control pueden ayudar a reducir la inflamación de las vías respiratorias provocada por el humo”, dijo Pedraza.

Pedraza ofreció varios otros consejos a cualquier persona que experimenta humo y restos de fuego:

• Permanezca dentro de casa el mayor tiempo posible, manteniendo las ventanas cerradas.
• Evite las actividades extenuantes al aire libre.
• Utilice ventiladores para mantenerse fresco; si utiliza aire acondicionado, ajuste el sistema para permitir la recirculación y evitar la entrada de aire del exterior.
• Utilice mascarillas N95 cuando esté al aire libre, especialmente en zonas con humo denso.
• Mantenga subidas las ventanillas del coche y ajuste las rejillas de ventilación para que recircule el aire.
• Asegúrese de tener a mano todos los medicamentos respiratorios necesarios. Si tiene asma pero no está tomando su inhalador de esteroides de mantenimiento, considere la posibilidad de volver a utilizarlo.

Para aquellos que experimentan un empeoramiento de los síntomas respiratorios, como tos incontrolada, sibilancias o dificultad para respirar, Pedraza dijo que deben ponerse en contacto con su médico lo antes posible. Cedars-Sinai Urgent Care también está disponible para apoyar a los pacientes.

“Patients with airway diseases, such as pulmonary fibrosis, COPD and asthma, may experience worsening of symptoms due to exposure to poor air quality from wildfire pollutants,” said Isabel F. Pedraza, MD, an assistant professor of Medicine and director of the Medical Intensive Care Unit at Cedars-Sinai. “We want to ensure that our patients have access to care when they most need it.”

Pulmonology patients, Pedraza said, should be sure to take their inhalers as prescribed, as well as any other “controller” medications that contain an inhaled steroid.

“Both inhalers and controller medications can help reduce the airway inflammation brought on by smoke,” Pedraza said.

Pedraza offered several other tips to anyone experiencing smoke and fire debris:

• Stay indoors as much as possible, keeping windows closed.
• Avoid strenuous outdoor activities.
• Use fans to keep cool; if you are using air conditioning, adjust the system to allow for recirculation and prevent intake from outdoor air.
• Wear N95 masks when outdoors, especially in areas with dense smoke.
• Keep car windows rolled up and set vents to recirculate air.
• Ensure you have all necessary respiratory medications on hand. If you have asthma but are not currently on your maintenance steroid inhaler, consider restarting the inhaler.

For those experiencing worsening respiratory symptoms—such as an uncontrolled cough, wheezing or shortness of breath—Pedraza said patients should contact their care provider as soon as possible. Cedars-Sinai Urgent Care is also available to support patients.

The catastrophic wildfires raging throughout Los Angeles County present special concerns for adults and children with respiratory illnesses. Irina Dralyuk, MD, a Cedars-Sinai Guerin Children’s pulmonologist and Isabel F. Pedraza, MD, a pulmonologist in the Department of Medicine at Cedars-Sinai, are available for interviews to discuss topics such as how smoke can damage lungs, how to recognize respiratory distress and how to keep your children and family members safe.

“Parents of children with a history of lung issues need to be especially cautious,” said Dralyuk, MD. “That means premature infants, children with asthma, cystic fibrosis and severe allergies as well as children with weak or compromised immune systems.”

Dralyuk adds that parents should track the air quality measurement on their smart phones and whenever the air quality measurement is 125 or above, they should keep their children inside. Wednesday morning’s air quality measurement was above 400.

“If parents notice their children struggling with a persistent cough, wheezing or shortness of breath, seek medical attention immediately,” Dralyuk said.

Dralyuk and Pedraza also can discuss prevention tips, including:

• Using air purifiers and humidifiers
• Keeping windows and doors closed
• Wearing air filtration masks—not the simple anti-COVID-19 masks
• Checking asthma medications to make sure they have not expired
• Washing hands frequently
