After graduating from medical school at the University of Miami, he completed his internal medicine residency and cardiology fellowship at Jackson Memorial Hospital, the University of Miami, and the Miami VA healthcare system. During his training he became focused on clinical research, quality of care, and outcomes within cardiology which lead him to acquire several large national datasets from the National Heart, Lung, and Blood Institute (NHLBI) from which he has published numerous peer-reviewed manuscripts and presented numerous abstracts at both the American College of Cardiology (ACC) and American Heart Association (AHA). Further he has authored a text book chapter on Guidelines and Appropriate Use Criteria for nuclear cardiac imaging. After completing his post-graduate training, Dr. Marzouka spent a year in private practice before returning to academia where he now focuses on high risk cardiovascular disease post-discharge, heart failure, cardiac imaging, teaching, and research. His research continues to evaluate new cardiovascular drug therapies for heart failure while using predictive analytic techniques to help clinicians identify habits, behaviors, and other factors that cause or protect against cardiovascular diseases. He is currently the principle investigator for the GALACTIC-HF trail at the Miami VA.
