Cui K, et al. - Among patients with ST-segment elevation myocardial infarction and multivessel coronary disease who underwent primary percutaneous coronary intervention (PCI) (n=1,205), researchers compared the long-term outcomes of staged complete revascularization and culprit-only PCI in order to ascertain the relative benefit in this patient population. A total of 576 patients underwent staged PCI and 629 had culprit-only PCI from January 2006 to December 2015, of these, 415 pairs of patients were identified after propensity-score matching. Findings revealed the superiority of staged complete revascularization to culprit-only PCI at 5-year follow-up. Nevertheless, diabetic patients showed a reduced benefit with staged PCI.
