About the investigator

Dr. John N. Makaryus was born and raised in New York. He completed his medical school training at the State University of New York, Downstate Medical Center in 2006, graduating with a Distinction in Research. He then went on to complete his Internal Medicine Residency, Chief Medical Residency, and Cardiovascular Disease Fellowship at the North Shore-LIJ Health System. Following his training, Dr. Makaryus went on to complete an Advanced Cardiovascular Imaging Fellowship at Columbia University-New York Presbyterian Hospital in New York City where he received training in modern cardiac imaging techniques with a particular focus on Nuclear Cardiology including Positron Emission Tomography, as well as cardiac CT/MR imaging and echocardiography.

He has authored over 40 peer-reviewed publications, book chapters, reviews, and editorials in the field of Cardiology, with a particular focus on cardiovascular imaging and has presented at both national and international conferences. His research interests include optimizing the application and integration of cardiovascular imaging into the diagnosis and therapeutic management of patients with cardiovascular disease. In 2014 he returned to North Shore University Hospital where he currently serves as the Director of Nuclear Cardiology.
