Summary

Emergency percutaneous coronary intervention (PCI) of an infarcted coronary artery is an efficacious treatment for patients with acute ST-segment elevation myocardial infarction (STEMI). However, the value of performing PCI on these arteries (preventive PCI) during primary PCI for STEMI is unknown. The objective of the Preventive Angioplasty in Myocardial Infarction trial [PRAMI; Wald DS et al. N Engl J Med 2013] was to determine whether preventive PCI performed during the same procedure as the infarct-artery PCI would reduce the incidence of cardiac-related death, nonfatal MI, or refractory angina with evidence of ischemia.
