What is a Heart Attack?

A heart attack occurs when there is a critical build up of blockage, usually with (but sometimes without) plaque breaking open and clot formation within an artery supplying blood to the heart. In some cases, there is spasm of the artery (muscle in the artery wall clamps down the artery) which decreases blood flow. In both cases, without adequate blood and oxygen flow to the heart muscle, the heart muscle can be damaged and die. If not treated quickly, this can result in permanent heart dysfunction and/or death.
