Abstract
As it is controversial whether metabolic syndrome (MetS) affects cardiovascular outcomes in patients who underwent percutaneous coronary intervention (PCI), we investigated the impact of MetS on clinical outcomes in patients who underwent PCI with everolimus-eluting stents (EESs). Patients who underwent PCI with EESs from 2009 to 2013 were included in this single-center, prospective cohort study. A composite event consisted of repeat revascularization, nonfatal myocardial infarction, and cardiac death. Of 903 patients observed for 4.9 years (median 1.8 years), 570 were diagnosed with MetS. The MetS group displayed more severe coronary artery disease and underwent more extensive PCIs than did the non-MetS group. The overall composite event rate was not significantly different between the MetS and the non-MetS group (11.9% vs 13.2%, p = 0.572). Kaplan-Meier survival analysis showed no significant difference in the event-free survival of the composite event between the 2 groups (p = 0.700). A multivariable Cox regression analysis showed that MetS was not associated with the composite event, whereas total stent length, decreased renal function, diabetes, and the absence of abdominal obesity were associated with the composite event. Abdominal obesity was associated with decreased risk of the composite event, alleviating unfavorable clinical outcomes of patients with diabetes in the MetS group. In conclusion, MetS has no impact on the clinical outcomes of patients who 'underwent PCI with EESs, although the MetS group exhibited more severe coronary artery disease and underwent more extensive PCIs. The paradoxical association between obesity and favorable clinical outcomes may explain this result. (C) 2015 Elsevier Inc. All rights reserved.
