The risks and benefits of stent postdilation in primary percutaneous coronary intervention (PPCI) in patients with ST\u2010elevation myocardial infarction (STEMI) have remained controversial. We sought to evaluate the immediate angiographic and long\u2010term outcomes in patients with and without stent postdilation.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>A cohort of patients (<jats:italic>n<\/jats:italic> = 1,224) with STEMI, treated with PPCI (<jats:italic>n<\/jats:italic> = 500 postdilated; <jats:italic>n<\/jats:italic> = 724 controls), were studied. The flow grade, the myocardial blush grade, and the frame count were considered angiographic outcomes. The clinical outcomes were major adverse cardiovascular events (MACE)\u2014comprising cardiac death, nonfatal MI, and repeat revascularization\u2014and the device\u2010oriented composite endpoint (DOCE)\u2014consisting of cardiac death, target lesion revascularization, and target vessel revascularization.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The flow and myocardial blush grades were not different between the two groups, and the frame count was significantly lower in the postdilation group (15.7\u2009\u00b1\u20098.4 vs. 17\u2009\u00b1\u200910.4; <jats:italic>p<\/jats:italic>\u2009&lt;\u2009.05).
