BackgroundMultivessel disease (MVD) is common in patients with ST-segment elevation myocardial infarction (STEMI), but optimal treatment management remains undetermined.MethodsIn this retrospective cohort study, 602 consecutive STEMI patients with MVD were enrolled between January 1, 2010 and October 1, 2014. Three hundred and eighty-two patients underwent culprit-only revascularization and 220 underwent staged complete revascularization. Primary end points were a composite of cardiac mortality or nonfatal reinfarction.ResultsThe mean duration of follow-up was 35 months (12–71 months). Following multivariate analysis, staged complete revascularization was associated with a lower rate of the composite of cardiac mortality or nonfatal reinfarction [HR: 0.430, 95 % CI: 0.197–0.940, P = 0.034] and unplanned repeat revascularization [HR: 0.343, 95 % CI: 0.166–0.708, P = 0.004] compared with culprit-only revascularization.ConclusionsCompared with culprit-only revascularization, staged complete revascularization significantly reduced the rate of the composite of cardiac mortality or nonfatal reinfarction, and the need for unplanned repeat revascularization.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
