Prognostic implications of procedural vs spontaneous myocardial infarction: Results from the Evaluation of Drug Eluting Stents and Ischemic Events (EVENT) registry

Among patients undergoing PCI, spontaneous but not procedural MI was independently associated with death and cardiovascular death at 1 year. These finding suggest that the prognostic impact of procedural MI may be less than that of spontaneous MI and should be considered in designing end points for future studies of coronary revascularization.
