Signs and Symptoms of Heart Attack

Heart attack occurs when the blood supplying oxygen to the heart is greatly reduced or completely cut off. This can be the result of a buildup of fat, cholesterol and other substances, also known as plaque. Your blood supply can then begin to clot around the plaque, blocking the flow to the heart, depriving it of the oxygen necessary to continue working. The resulting damage, or even death, of the affected heart muscle is called a heart attack.
