Heart attacks occur when blood supply to the heart is blocked, depriving the heart tissues of oxygen, explains Better Health. If the blockage persists, the heart tissue dies, resulting in a cardiac arrest. In a mild heart attack, there is partial blockage of the blood circulation to the heart muscles. The cardiac muscles continue receiving oxygen, albeit in limited quantities; hence, there is no permanent damage to heart muscles.

Although a mild heart attack does not cause permanent cardiac muscle damage, it is still a serious heart condition that requires urgent medical attention, notes Better Health. Unless it is it arrested, a mild heart attack can result in more serious cardiac damage. Even though a mild heart attack affects a small portion of the heart muscle and lasts briefly, it has the potential to cause life-threatening symptoms, such as arrhythmia and heart failure.
