ST-segment elevation myocardial infarction in severe coronary artery stenosis: a case series.

Recently, it has been reported that acute ST-segment elevation myocardial infarction (STEMI) frequently develops at the site of severe stenosis. This impression was derived from the observation of stenosis severity after aspiration of the thrombus leading to the event. In the past, STEMI was considered as a thrombotic event on a non-flow limiting coronary plaque mainly. We report a case series of patients who developed STEMI within hours to days of initial angiography, all of whom demonstrated severe flow limiting coronary artery stenosis.
