Heart Attack. CAD occurs when fatty deposits (called plaque or atheroma) slowly build up on the inner wall of the coronary arteries and cause the arteries to become narrow. This triggers blood platelets and other substances to form a blood clot at the site that blocks most or all of the oxygen-carrying blood from flowing to a part of the heart muscle. Trends in reperfusion strategies, door‐to‐needle and door‐to‐balloon times, and in‐hospital mortality among patients with ST‐segment elevation myocardial infarction enrolled in the National Registry of Myocardial Infarction from 1990 to 2006.
