Heart Attack

A heart attack refers to the death of heart muscle from the sudden blockage of a coronary artery by a blood clot. Coronary arteries are blood vessels that supply the heart muscle with blood and oxygen. When coronary arteries are blocked, the heart muscle is deprived of blood and oxygen and becomes injured.

Heart attacks most often occur as a result of coronary artery disease, a condition in which a waxy substance called plaque builds up inside the coronary arteries. An area of plaque can rupture inside of an artery and cause a blood clot to form on the plaque’s surface. If the clot becomes large enough, it can block blood flow through a coronary artery.

If the blockage isn’t treated quickly, the portion of heart muscle fed by the artery begins to die and healthy heart tissue is replaced with scar tissue.
