INTRODUCTION AND OBJECTIVES: The optimal treatment of patients with multivessel coronary artery disease and ST-segment elevation acute myocardial infarction (STEMI) who undergo primary percutaneous coronary intervention (PCI) is controversial. The aim of this study was to access the prognostic impact of multivessel PCI vs culprit vessel-only PCI in real-world patients with STEMI and multivessel disease.

METHODS: This was a retrospective cohort study of 1499 patients with STEMI diagnosis who underwent primary PCI between January 2008 and December 2015. About 40.8% (n=611) patients had multivessel disease. We performed a propensity score matched analysis to obtain 2 groups of 215 patients paired according to whether or not they had undergone multivessel PCI or culprit vessel-only PCI.

RESULTS: During follow-up (median, 2.36 years), after propensity score matching, patients who underwent multivessel PCI had lower rates of mortality (5.1% vs 11.6%; Peto-Peto P=.014), unplanned repeat revascularization (7.0% vs 12.6%; Peto-Peto P=.043) and major acute cardiovascular events (22.0% vs 30.8%; Peto-Peto P=.049). These patients also showed a trend to a lower incidence of myocardial infarction (4.2% vs 6.1%; Peto-Peto P=.360).

CONCLUSIONS: In real-world patients presenting with STEMI and multivessel coronary artery disease, a multivessel PCI strategy was associated with lower rates of mortality, unplanned repeat revascularization, and major acute cardiovascular events.
