Dr. Nsair is the Director of the Heart Transplantation and Mechanical Circulatory Support Program at UCLA. As well, he is a member of the Interventional and structural program at UCLA. He received his MD from the University of Alberta, where he also completed his Internal Medicine residency and Cardiology fellowship. He received advanced training in Advanced Heart Failure and Interventional Cardiology at UCLA Medical Center and a post-doctoral fellowship in Regenerative Therapies. His research interests include cardiovascular regenerative and rejuvenation therapies, as well as advanced studies of mechanical circulatory support devices in cardiogenic shock and novel heart failure medical therapies.
Dr. Nsair has strong interest in sports medicine and extensive expertise in managing cardiovascular disease in patients of all athletic levels. As well he is a skilled proceduralist in coronary and structural heart interventions. Current research interest focuses on implantable and wearable technologies in heart failure patients and athletics. Furthermore, his research interest involves mechanical circulatory support in patients with advanced heart failure and cardiogenic shock. He is involved in multiple clinical and translational trials and is the PI for a basic and translational research lab.
