- Abstract
- Introduction and objectives: There are limited data on the preferred treatment strategy in ST-segment elevation myocardial infarction (STEMI) patients with bifurcation lesions. This study aimed to compare clinical outcomes between 1-stent and 2-stent strategies in STEM! patients with bifurcation lesions undergoing primary percutaneous coronary intervention (PCI). Methods: The COronary Bifurcation Stenting II is a retrospective multicenter registry of 2897 consecutive patients with bifurcation lesions undergoing PCI with drug-eluting stents from January 2003 through December 2009. Among the registered population, 367 (12.7%) patients had STEMI; of these, a 1-stent strategy was used in 304 patients and a 2-stent strategy in 63 patients; 77.1% of the patients received primary PCI with a first-generation drug-eluting stent. The inverse-probability-of-treatment-weighting method was used to adjust for confounding factors. The primary outcome was major adverse cardiovascular events (MACE), a composite of cardiac death, myocardial infarction, target lesion revascularization, and stent thrombosis. Results: The median length of follow-up was 38 months. Postprocedural side branch diameter stenosis differed significantly between the 2 groups (1-stent vs 2-stent, 42.7% vs 9.7%; P < .001). After the performance of inverse-probability-of-treatment-weighting methods, the rate of MACE was significantly higher in the 2-stent group than in the 1-stent group (HR, 1.85; 95%CI, 1.19-2.87; P = .006), mainly driven by target lesion revascularization and stent thrombosis. Conclusions: In STEMI patients with bifurcation culprit lesions undergoing primary PCI, the 2-stent strategy had significantly higher rates of MACE than the 1-stent strategy, despite successful treatment of the side branch. However, this result should be interpreted with caution because this study does not reflect current practice. (C) 2018 Sociedad Espaiiola de Cardiologia. Published by Elsevier Espana, S.L.U.
