Heart Attack



Heart Attack Causes


A heart attack occurs when one or more of the arteries supplying the heart with oxygen-rich blood become blocked. These arteries are called coronary arteries and encircle the heart like a crown. Over time, a coronary artery narrows from the buildup of cholesterol. This buildup collectively known as plaques in arteries throughout the body is referred to as atherosclerosis.


Heart Attack Definition


A heart attack usually happens 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. Interrupted blood flow to the heart can destroy a part of the heart muscle.
