In brief: Overlap sometimes

Asystole is no beat at all.
Flaccid still heart. Cardiac arrest : includes that and ventricular fibrillation or tachycardia, which are ineffective rhythyms and no pulse. These can happen with a heart attack which is death of some portion of the heart muscle.

In brief: Big Difference

A "heart attack" is damage to the heart as a result of the lack of blood flow to the heart.
Cardiac arrest means that the heart muscle has stopped beating. Many times, a heart attack can lead to cardiac arrest. But, they are not the same. And there are other causes for cardiac arrest besides heart attacks.
