Dr. Barouch is currently Associate Professor of Medicine in the Division of Cardiology and a member of the Advanced Heart Failure and Cardiac Transplantation group at the Johns Hopkins University School of Medicine. Dr. Barouch received her undergraduate degree from Harvard University in 1992 and her medical degree from Johns Hopkins in 1996. She continued at Johns Hopkins for residency training in Internal Medicine, completed in 1999, and fellowship in Cardiovascular Disease and Advanced Heart Failure/Transplant, completed in 2003.

Dr. Barouch has a longstanding interest in women’s cardiovascular health – particularly in how some cardiac conditions affect women differently or present with distinctive symptoms. She also has specific expertise in peripartum cardiomyopathy, heart failure after cancer treatment, and the role of obesity in the development of congestive heart failure. She has been a member of the Johns Hopkins cardiology faculty since 2003 and has performed extensive independent research within the Cardiovascular Division. Dr. Barouch cares for general cardiology and heart failure patients at her primary clinical location in Columbia, Maryland, where she is working to establish a Women’s Heart Health Program.

She believes that educating people about heart disease, medications and lifestyle changes, including healthy eating habits and regular exercise, is critically important in helping her patients understand how to achieve and maintain wellness and feel in control of their cardiovascular health. She is an avid runner and triathlete herself, competing in several triathlons and other races per year, as well as the occasional marathon. more
