Heart attack increases the risk of sudden cardiac arrest but the two are not the same. A heart attack occurs when the blood supply to the heart muscle is partly or completely blocked, and the muscle itself is injured or dies. This can happen when one of the arteries that supply blood to the heart is obstructed, usually by plaque. Fortunately, lifestyle changes can help reduce the risk of a heart attack. With proper treatment, many people survive this cardiac emergency.
In contrast, sudden cardiac arrest is brought on by an "electrical accident" in the heart. The heart's pumping mechanism is normally powered by electrical signals. In sudden cardiac arrest, these signals suddenly grow irregular or shut off. The heart may stop altogether or it may simply flutter or quiver in an abnormal rhythm (arrhythmia). Most commonly, an arrhythmia known as ventricular fibrillation (VF) causes SCA. The victim loses a pulse and consciousness. Without immediate treatment the individual will die.
Unfortunately, changes in lifestyle do not necessarily reduce the risk of sudden cardiac arrest, although certain safeguards and solutions are available for those at greater risk.
