Biography

James MacNamara, M.D., is an Assistant Professor in the Department of Internal Medicine at UT Southwestern Medical Center. He specializes in exercise physiology and advanced cardiac imaging, as well as shortness of breath and exercise intolerance in patients with heart failure with preserved ejection fraction and hypertrophic cardiomyopathy.

Dr. MacNamara earned his medical degree at the University of Virginia School of Medicine and completed his residency at the Emory School of Medicine. He then received advanced training in cardiology through a fellowship at UT Southwestern.

Certified by the American Board of Internal Medicine, he joined the UT Southwestern faculty in 2021.

He has published several academic articles in leading journals such as Circulation and Echocardiography.

Among many other honors, Dr. MacNamara received the University of Virginia School of Medicine’s 2013 Medical Student Teaching Award.
