Heart attack is the death of a segment of heart muscle caused by the loss of blood supply. The blood supply is usually lost because a coronary artery, one that supplies blood to the heart muscle, has a blood clot, a blockage (coronary thrombosis). If some of the heart muscle dies, the patient experiences chest pain and electrical instability of the heart muscle tissue.

I am not going to go into detail but heart attacks can get caused from stresses, panicking, unfit body/smoking ( to much junk that can cause cholesterol ( substances that blocks the valves in the veins of the body that stops the blood from flowing through) and of course many more but i am telling you the main ones. I am saying it in the simplest form possible. Hope that was what you were asking for :)
