A heart attack is the death of a segment of heart muscle caused by a loss of blood supply. The blood is usually cut off when an artery supplying the heart muscle is blocked by a blood clot.
If some of the heart muscle dies, a person experiences chest pain and electrical instability of the heart muscle tissue.
A heart attack occurs when the flow of blood to the heart is blocked. The blockage is most often a buildup of fat, cholesterol and other substances, which form a plaque in the arteries that feed the heart (coronary arteries).
The plaque eventually breaks away and forms a clot. The interrupted blood flow can damage or destroy part of the heart muscle.
