Heart attack. Computer composite artwork depicting a heart attack (myocardial infarction),showing an angiogram of coronary arteries and an ECG heart trace. A red ECG (electrocardiogram) trace reveals the electrical activity of an irregular heartbeat during a heart attack. In the background is an angiogram (X-ray) of the heart (grey) with coronary arteries (black) on its surface. Coronary arteries supply the heart muscle with oxygen. Blockage of one of these coronary arteries by a clot or narrowed artery walls in atherosclerosis starves the heart muscle of blood and is a typical cause of heart attack. Angiography is a technique used to detect blocked coronary arteries | |
