People often think that a heart attack is the same thing as a cardiac arrest. This, however, is not true. In order to understand the difference between a heart attack and a cardiac arrest, it is first necessary to understand what happens in both of these processes.What is a heart attack?The heart is a muscle, and like all muscles it requires an oxygen-rich blood supply. This is provided to the heart by coronary arteries. A heart attack occurs when there is a blockage of the coronary arteries. This is often caused by a blood clot. Such a blockage, if not quickly resolved, can cause parts of heart muscle to begin to die. (1-3)What is a cardiac arrest?A cardiac arrest is different to a heart attack. In a cardiac arrest the heart actually stops beating; whereas in a heart attack the heart normally continues to beat even though the blood supply to the heart is disrupted. (4, 5)
