The primary mission of the Cardiology Fellowship Program is to prepare the future leaders of cardiovascular medicine. We aim to develop expert clinicians, as well as basic and clinical investigators. In order to meet the rigors of cardiology in the 21st Century, we have developed two major training pathways. The Investigator track is designed for individuals interested in a career in academic cardiology. These individuals will complete 24 months of in-depth clinical training. An additional 2 to 3 years will be devoted exclusively to research. The research experience is designed to give the trainee the necessary tools in the techniques of investigator-initiated clinical and/or basic research (Research Program). The Clinician track will involve a 3-year training experience that will encompass a 6-month research experience. This track is designed to develop expert clinicians. It is anticipated that many of these individuals will pursue a fourth year in interventional cardiology or electrophysiology (recognized subspecialties of the ABIM) (Clinical Training).
