WHAT CAUSES A HEART ATTACK? Most heart attacks occur as a result of coronary heart disease (CHD) Coronary arteries (the major blood vessels that supply theheart with blood) get clogged up with deposits of cholesterol.These deposits are called plaques. During a heart attack, oneof the plaques ruptures (bursts), causing a blood clot todevelop at the site of the rupture. The clot may then blockthe blood supply runningthrough the coronary arteries to theheart, triggering a heart attack.
