Question: what is the cause of heart attacks

Hi RK.

I would say clogged or obstructed coronary arteries are the main cause. These arteries take oxygen and nutrients to the heart and the heart cannot work properly if they become obstructed. The heart can stop beating all together (heart attack) and the person would die if they are not given CPR and taken to the hospital immediately.
