What is the difference between cardiac arrest and heart attack?

April 21, 2022

From the Medical News Today website

It is common to confuse a cardiac arrest with a heart attack, as both are medical emergencies affecting the heart. However, they are not the same thing. A heart attack involves an interruption in the blood supply to the heart. It may lead to cardiac arrest, which is when the heart stops pumping. 

The American Heart Association (AHA) describes the difference between a heart attack and a cardiac arrest as a circulation issue compared with an electrical problem. 

With a heart attack, a blocked artery prevents blood flow to the part of the heart that the artery serves. This causes that part of the heart to begin to die. 

With a cardiac arrest, the heart has an electrical malfunction and stops beating suddenly. 

This article explains the differences between a heart attack, cardiac arrest, and heart failure. It also discusses the symptoms of each and explains what to do in an emergency.
