A blockage of blood flow to the heart muscle. A heart attack is a medical emergency. A heart attack usually occurs when a blood clot blocks blood flow to the heart. Without blood, tissue loses oxygen and dies. Symptoms include tightness or pain in the chest, neck, back or arms, as well as fatigue, lightheadedness, abnormal heartbeat and anxiety. Women are more likely to have atypical symptoms than men. Treatment ranges from lifestyle changes and cardiac rehabilitation to medication, stents and bypass surgery.     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.   If a piece of plaque cracks, it may cause a blood clot to form and block a coronary artery, cutting off the blood supply to a part of the heart muscle. This causes a heart attack. The heart attack symptoms you feel during a heart attack are caused by your he...
