Cause of heart attacks

The same process that causes ischemic strokes also causes heart attacks (called myocardial infarctions or MI in medical lingo)--that is, atherosclerosis [hardening of arteries]. In case, one or more of the arteries supplying blood to the heart muscle become occluded to the point that a suden blockage can occur by the formation of a blood clot at the site of the narrowing. Before an MI occurs, the person may experience episodes of sudden pain radiating either down the left arm or into the jaw, much like the warning attacks we see with strokes.

...when blockage of the blood supply to the heart muscle occurs, events take place much like those seen in the person having a stroke. The greatest damage to the heart muscle occurs closest to the territory of the blood vessel involved, sort of in cone-like shape with the tip of the cone at the site of vessel obstruction. Surrounding this core of severely damaged heart tissue is another zone of less damaged heart muscle, also called penumbra.
