Detailed explanation-1: -This is usually due to cholesterol-containing deposits called plaques. Plaques can narrow the arteries, reducing blood flow to the heart. If a plaque breaks open, it can cause a blood clot in the heart. A heart attack may be caused by a complete or partial blockage of a heart (coronary) artery.
Detailed explanation-2: -Coronary artery disease (CAD) is the main cause of heart attack. A less common cause is a severe spasm, or sudden contraction, of a coronary artery that can stop blood flow to the heart muscle.
Detailed explanation-3: -Acute coronary syndrome: This is the sudden form that’s a medical emergency. The plaque in your coronary artery suddenly ruptures and forms a blood clot that blocks blood flow to your heart. This abrupt blockage causes a heart attack.
