A myocardial infarction occurs when blood supply to a part of the myocardium (heart muscle) is interrupted, either by lack of blood flow, obstruction by a clot, or rupture of a plaque (a buildup of fat and other substances in the blood) in a coronary (heart) artery. Many individuals have coronary artery disease and do not know it until they have a heart attack or die suddenly as a result of myocardial infarction. The January 30, 2008, issue of JAMA includes a study about the use of stents (devices that help to hold diseased coronary arteries open).
