Cardiac Arrest vs Heart Attack

Cardiac arrest and heart attack are distinct medical events, often confused due to their association with the heart, but they have different causes and consequences. A heart attack, medically known as a myocardial infarction, occurs when blood flow to a part of the heart muscle is blocked, usually by a blood clot. This blockage can damage or destroy part of the heart muscle, leading to symptoms such as chest pain, shortness of breath, and fatigue.

On the other hand, cardiac arrest is a sudden, unexpected loss of heart function, usually caused by an electrical malfunction in the heart that disrupts its pumping ability. Unlike a heart attack, which involves a circulation issue, cardiac arrest results in the heart abruptly stopping its pumping action, leading to an immediate loss of consciousness and absence of a pulse.
