A 47-year-old member asked:

Is there a difference between a heart attack and cardiac arrest?

Dr. Nassir Azimi

No: A heart attack-or "myocardial infarction"-occurs when the blood and oxygen supply to a part of the heart is interrupted due to blockage of one or more of the arteries supplying blood to the heart. This causes the part of the heart supplied by that artery to die if the blockage is not opened very quickly. Cardiac arrest refers to a heart rhythm disturbance-most commonly ventricular fibrillation.
Dr. Robert Roth
Hospital-based practice 40 years experience
Yes: In a heart attack a heart artery is blocked, usually by a blood clot, and causes damage to a portion of the heart. While this can be fatal, most people with a heart attack survive with early recognition and treatment. Cardiac arrest is actual stoppage of the heart beating, which can be caused by many things and is rapidly fatal unless immediate CPR and advanced emergency techniques are applied.
Dr. Sue Ferranti

Yes...: Cardiac arrest is when the heart actually stops. A heart attack is due to decreased blood flow to a part of the heart muscle. A heart attack can lead to cardiac arrest, but not always. And, there are other etiologies of cardiac arrest besides heart attack.

Difference.....: A heart attack is when the heart muscle is not getting the blood supply it needs. The part of the heart not receiving enough blood is at risk to die. Cardiac arrest is when the heart stops beating entirely. One of the many causes of cardiac arrest is a heart attack or myocardial infarction (mi). Both are life-threatening and require an immediate 911 call.
