What is an inferior myocardial infarction from?

Many poss causes: An inferior mi refers to a heart attack on the inferior wall of the heart muscle. 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 all contribute to this process.

R coronary blocked: An inferior myocardial infarction is usually due to a blockage in the right coronary artery system causing damage to the inferior (bottom) of the heart. The mechanism is thought to be caused by a 'ruptured plaque' in the coronary artery. Plaque build up is caused by smoking, high cholesterol, diabetes, high blood pressure.
