Having graduated as valedictorian from New York Medical College in 1972, Dr. Ambrose completed his internship, residency, and fellowship training at Mount Sinai Hospital in New York, where he dedicated 25 years of his career. Ascending to the rank of Professor of Medicine and serving as the Director of the Cardiac Catheterization Laboratory for 14 years, it was during this period that Dr. Ambrose formulated the pivotal concepts underpinning the pathogenesis of acute syndromes. His seminal papers, produced in collaboration with esteemed mentors such as Richard Gorlin and Valentín Fuster, underscore his enduring contributions.
Following his tenure at Mount Sinai, Dr. Ambrose assumed the role of Director of the Cardiovascular Center at St. Vincent’s Hospital and Medical Center in New York City. However, he departed after five years, predating the hospital’s declaration of bankruptcy. In 2005, he relocated to Fresno, where he served as Chief of Cardiology and Director of the Cardiology Fellowship Program at UCSF Fresno until 2017.
A Fellow of the American College of Cardiology, Dr. Ambrose is board certified in both cardiovascular disease and internal medicine by the American Board of Internal Medicine (ABIM). The ABIM is a physician-led, non-profit, independent evaluation organization driven by doctors who want to achieve higher standards for better care in a rapidly changing world.
Cardiology is a branch of medicine that deals with the disorders of the heart, as well as some parts of the circulatory system. The field includes medical diagnosis and treatment of congenital heart defects, coronary artery disease, heart failure, valvular heart disease, and electrophysiology. Cardiologists are doctors who diagnose, assess, and treat patients with diseases and defects of the heart and blood vessels (the cardiovascular system).
In the course of his professional journey, Dr. Ambrose has mentored over 250 fellows, authored more than 300 papers featured in various journals and books, and has a dedicated Wikipedia page. Consistently acknowledged in the “Best Doctors in America” publication, he attributes his accomplishments to his meticulous attention to detail, sound common sense, sharp judgment abilities, and a voracious reading habit.
