Metabolic syndrome and risk of restenosis in patients undergoing percutaneous coronary intervention, Diabetes Care 28

Abstract

OBJECTIVE — Patients with metabolic syndrome have increased risk of cardiovascular events. The number of patients with metabolic syndrome is rapidly increasing, and these patients often need revascularization. However, only limited data are available on the effect of metabolic syndrome on restenosis in patients undergoing percutaneous coronary intervention (PCI). RESEARCH DESIGNANDMETHODS — To assess the role of metabolic syndrome in the development of restenosis, we performed an analysis in a population of patients from the GENetic DEterminants of Restenosis (GENDER) study. The GENDER project, a multicenter prospective study, included consecutive patients after successful PCI and was designed to study the predictive value of various genetic and other risk factors for subsequent clinical restenosis, defined as target vessel revascularization (TVR) or combined end point of death, myocardial infarction, and TVR. This subpopulation of GENDER consisted of 901 patients, 448 of whom (49.7%) had metabolic syndrome. RESULTS — On multivariable Cox regression analysis, controlling for age, sex, previous myocardial infarction, stent length, current smoking, and statin therapy, there was no association between increased risk of TVR (hazard ratio 1.03 [95 % CI 0.68–1.57]) or the combined en
