Dr. Arash Nayeri is a UCLA-trained cardiologist who is board certified in cardiovascular diseases, echocardiography, and nuclear cardiology. He completed an extended fellowship in cardiovascular medicine at the David Geffen School of Medicine at UCLA with an emphasis on clinical research focused on evidence-based treatment of heart failure, valvular heart disease, and prevention of cardiovascular events.
He is a Fellow of the American College of Cardiology (FACC) and a Fellow of the American Society of Echocardiography (FASE), reflecting his commitment to continued excellence, innovation, and leadership in clinical cardiology and advanced cardiovascular imaging.
Dr. Nayeri has a lengthy history of clinical research with more than 30 peer-reviewed publications and over 50 presentations at national conferences, including the American Heart Association (AHA) and the American College of Cardiology (ACC) Scientific Sessions. He views his research background as instrumental in providing evidence-based, individualized care for every patient.
His research and clinical interests include cardiomyopathy and heart failure, where he has obtained grant funding for research on the appropriate diagnosis and management of rarer and previously neglected variants. He has also published extensively and maintains active clinical interests in:
- Cardio-oncology, with an emphasis on the prevention and treatment of cardiovascular complications related to traditional chemotherapy and newer immunotherapy agents.
- Valvular heart disease, with an emphasis on echocardiographic screening, longitudinal monitoring, and the optimal timing of surgical or minimally invasive intervention.
- Primary prevention of cardiovascular disease, including advanced cardiovascular risk assessment, dyslipidemia management, refractory hypertension, and evidence-based strategies to prevent future cardiovascular events.
- Cardiovascular rehabilitation, with a focus on improving quality of life and long-term outcomes for patients with heart failure and coronary artery disease.
Dr. Nayeri is engaged in pioneering clinical research focused on women's cardiovascular health. He is building prospective registries examining diastolic dysfunction in perimenopausal women and non-calcified coronary artery disease diagnosed through coronary CT angiography with AI-enabled plaque analysis. His work highlights the limitations of traditional cardiovascular screening tools, such as coronary artery calcium scoring, in this patient population. He collaborates closely with women's health specialists and primary care providers and is a repeat speaker at the ACC Contemporary Management of Cardiovascular Disease in Women symposium.
Dr. Nayeri has developed particular expertise in coronary CT angiography and AI-enabled cardiovascular imaging for the early detection and prevention of heart disease. He has collaborated with HeartFlow in product design and public policy advocacy and provides educational programs for physicians across the country on the clinical application of advanced AI-enabled cardiovascular imaging.
COR Medical serves as the clinical site for HeartFlow's GameFilm Registry for former NFL players and maintains a substantial registry of coronary CT angiography studies in executives, CEOs, entrepreneurs, and other high-performing professionals. This work is focused on the early detection and treatment of cardiovascular disease in a unique patient population with heightened occupational stress and elevated long-term cardiovascular risk. Through advanced imaging and personalized risk assessment, Dr. Nayeri emphasizes proactive prevention strategies designed to identify disease before symptoms or major cardiac events occur.
Dr. Nayeri characterizes his patient care philosophy as the individualized application of evidence-based medicine. He believes that patient education, shared decision-making, and a personalized approach to prevention and treatment are fundamental to delivering exceptional cardiovascular care.
Many of Dr. Nayeri's patients - including executives, CEOs, entrepreneurs, former professional athletes, and individuals seeking advanced preventive cardiovascular care -travel from across the country, including San Francisco, Florida, New York, and Aspen, for a coordinated, concierge-level cardiac evaluation in Los Angeles.
Dr. Nayeri was named by his peers to the Southern California Super Doctors® Rising Stars list in a special publication distributed with the Los Angeles Times (January 2025). Physicians recognized in this distinction are selected through independent research and peer evaluation.
In addition, Dr. Nayeri has been selected as a Castle Connolly Top Doctor Rising Star. Through a rigorous physician-led nomination and research process, Castle Connolly recognizes outstanding physicians who demonstrate excellence in clinical care and professional achievement.
He has also been recognized by Los Angeles Magazine as one of its Top Cardiologists in the Top Doctors issue (May 2025).
Dr. Nayeri graduated with a Bachelor of Arts in Molecular and Cell Biology from the University of California, Berkeley, where he received both the Departmental Citation and Outstanding Scholar Award and the Outstanding Graduate Student Instructor Award. He earned his medical degree from Vanderbilt University School of Medicine as a recipient of the prestigious full merit-based Cornelius Vanderbilt Scholarship. He completed both his internal medicine residency and cardiology fellowship at the David Geffen School of Medicine at UCLA, where he received the Fellow Teaching Award.
