No, because damaged muscle, whether it is heart or skeletal, does not regenerate. If damage is minimal, then the surrounding heart muscle may increase in strength to compensate, such as happens in skeletal muscle damage, but 100% normality is rarely regained. This assumes a real heart attack (infarction), and not a severe angina attack. They are different events, but symptoms might be similar.

We rapid reperfusion (opening the blocked vessel), some myocytes that have not reached irreversible degeneration can be save. The mechanisms of cardiac regeneration by stem cells, both from the body or introduced, is being studied.
