No but angina and heart attack occur because of the same disease. With angina there is a demand supply imbalance, where the heart muscle does not receive enough oxygen/blood because the vessels that supply the heart are narrowed. The bodies response to this is pain. A heart attack occurs when there is blockage (usually as a result of platelet thrombi) in the artery for a prolonged period of time in which the heart muscle is deprived of oxygen and blood, the results in part of the heart muscle dying. This is defined as an MI. The main difference is that an angina attack dosen't cause permanent damage to the heart muscle.
