Myocardial infarction causes?

Many poss causes: Almost all heart attacks are the result of fatty deposits on the inside of arteries that break open and cause clotting which will blocks the artery (and the blood from flowing to the part of the heart the artery feeds). Family history, fatty diet, smoking, high blood pressure, diabetes and other disorders can all contribute to this process.

Heart cell death: Myocardial infractions happen when heart muscle dies from lack of oxygen delivered by blood. This can happen when plaque deposits in the vessels rupture and cause total blockage of a vessel. It can also happen if there is a narrowing of the vessel severe enough that oxygen delivery is far below demand (especially if oxygen demand is increased).
