About every 40 seconds, someone in America has a heart attack. A heart attack is an urgent message that your heart needs oxygen. The most common cause is coronary artery disease. When a blockage or plaque within a coronary artery ruptures or breaks, a blood clot forms around it. This blood clot can block the oxygen-rich blood from getting to the muscle of your heart. That causes the heart muscle to start dying, and you begin to feel the symptoms of a heart attack. Your doctor may also refer to this as, “acute myocardial infarction."
