Question

what is the difference between cardiac arrest and heart attack ?

Answer 1

A heart attack is when one of the coronary arteries becomes blocked. The heart muscle is robbed of its vital blood supply and, if left untreated, will begin to die because it is not getting enough oxygen. A cardiac arrest is when a person's heart stops pumping blood around their body and they stop breathing normally.

Answer 2

there is a difference between a heart attack and a cardiac arrest. A heart attack occurs when the blood supply to part of the heart stops and thus causes a section of the heartmuscle to begin to die; whereas acardiac arrest occurs when the heartstops beating as a whole.
