A heart attack usually occurs when a blood clot blocks the flow of blood through a coronary artery — a blood vessel that feeds blood to a part of the heart muscle. The interrupted blood flow that occurs during a heart attack can damage or destroy a part of the heart muscle.
A heart attack, also called a myocardial infarction, can be fatal. Treatment for heart attack has improved dramatically over the years. It is crucial to promptly recognize symptoms and call 911 or emergency medical help if you think you might be having a heart attack.
