Professor of Pediatrics, Physiology, and Medicine
Associate Chairman of Pediatrics at NY Medical College
Director of the Center for Hypotension at NY Medical College
The Center for Hypotension at NY Medical College is funded by the National Heart, Lung and Blood Institute of the National Institutes of Health, and is the premier research institution in the world studying the scientific bases of orthostatic intolerance in the young.
Orthostatic intolerance, the inability to remain upright relieved by recumbence, is epitomized by vasovagal syncope (simple faint, neurocardiogenic syncope) and by chronic orthostatic intolerance, also called the postural tachycardia syndrome.
Dr. Stewart graduated from Cornell University with a degree in physics.
He obtained both MD and PhD from the University of Chicago having been selected to enroll in the prestigious Medical Scientist Training Program (MSTP) where his research work in cardiac physiology was completed with Dr. Ernest Page.
He did internship and residency at New York University, completing his fellowship in Pediatric Cardiology at Cornell University-New York Hospital.
Dr. Stewart has more than 130 scientific papers published in high-impact cardiology and physiology journals; he has first authored the majority of those manuscripts, and last authored the remainder. He has published five book chapters. He has trained graduate students, MD, PhD students and post doctoral Fellows. He is currently on the Editorial Board of Circulation and the American Journal of Physiology, Heart and Circulatory Physiology. He has been on diverse ad hoc NIH study panels and recently completed participation as permanent member of the Clinical Investigative Cardiovascular Science (CICS) study section.
At present his clinical and research work focus on discovering the underlying mechanism of vasovagal syncope. This should be of great practical significance because nearly 50% of the population suffers at least one fainting episode.
