The blood supply is usually lost because a coronary artery, one that supplies blood to the heart muscle, has a blood clot, a blockage (coronary thrombosis). If some of the heart muscle dies, the patient experiences chest pain and electrical instability of the heart muscle tissue.
Another name for a heart attack is myocardial infarction,cardiac infarction and coronary thrombosis.
