Jennifer A. Tremmel, MD, MS

Clinical Director, Women's Heart Health

Assistant Professor, Division of Cardiovascular Medicine

Dr. Tremmel is the clinical director of the Women's Heart Health program. She is an interventional cardiologist who also trained in preventive cardiology. In her clinic she cares for women who are at high risk for coronary artery disease, women who have symptoms concerning for heart disease, and women who already have heart disease. She has a particular interest in women who present with symptoms of heart disease, but are found to have "normal" coronary arteries on angiography. Her current research investigates whether women presenting like this are more likely than men to have coronary abnormalities that cannot be detected by angiography alone, such as endothelial dysfunction, diffuse deposition of plaque, or microvascular disease.

Dr. Tremmel received her bachelor's degree in psychology and her medical degree from the University of Iowa. She did her internal medicine internship and residency at Dartmouth-Hitchcock Medical Center. Following that she obtained a master's degree in epidemiology at the Harvard School of Public Health.
