Running and the Heart 1



Figure 1. The outside of the heart. The heart gets its blood supply from the coronary arteries. When the heart does not get enough blood through these arteries, a person can experience a “heart attack” or myocardial ischemia. Heart attacks are the most common cause of sudden cardiac death in runners over 40. Image by the The Society of Thoracic Surgeons.
