Heart Attack (Myocardial Infarction)

A heart attack is permanent damage to the heart. The heart needs a constant supply of oxygen-rich blood to keep it nourished, and the coronary arteries provide the heart with this crucial blood supply. But if a person has coronary artery disease, the most common cause of heart attacks, the arteries can become narrowed and blood cannot flow as easily as it should. Arteries also can become clogged with fat, calcium, proteins and inflammation, also called plaque, which can rupture inside arteries and cause a blood clot. If the clot is large enough, it starves the heart of oxygen. When arteries are mostly or completely blocked, heart muscle cells begin to die, causing permanent damage.
