A STEMI (ST-segment elevation myocardial infarction) is an MI that damages the full thickness of the myocardium in a certain area. It is considered the most dangerous type of MI as it can lead to more extensive damage and complications. It usually causes the development of significant Q waves on the EKG. A subendocardial MI, on the other hand, only damages the innermost layer of myocardium and typically does not produce Q waves on the EKG.
