In this week’s Medical Minute, Dr. Joseph Hobbs, chairman of the Department of Family Medicine at the Medical College of Georgia at Augusta University, discusses how disease in the tiny blood vessels that feed each cell in our heart can make it tough for the heart to get the blood it needs during periods of exertion.

The Medical Minute airs at 8:18 a.m., 1:20 p.m. and 5:18 p.m. every Saturday and Sunday on the 17 GPB radio stations across Georgia. For more Medical Minute episodes, visit the GPB Augusta SoundCloud page.
