Heart Attack: Warning signs and tips on prevention


A heart attack (also called myocardial infarction) is when part of the heart muscle is damaged or dies because it isn't receiving oxygen. Oxygen is carried to the heart by the arteries (blood vessels). Most heart attacks are caused by a blockage in these arteries. Usually the blockage is caused by atherosclerosis, which is the buildup of fatty deposits (called plaque) inside the artery. This buildup is like the gunk that builds up in a drainpipe and slows the flow of water.

Heart attacks can also be caused by a blood clot that gets stuck in a narrow part of an artery to the heart. Clots are more likely to form where atherosclerosis has made an artery more narrow.
