Clinical presentation and predictors of target vessel revascularization after drug-eluting stent implantation

摘要

Background: Drug eluting stent (DES) failure including restenosis and stent thrombosis, or disease progression may result in target vessel revascularization (TVR) but the relative contribution of these mechanisms in the DES era is not well described. We sought to examine the predictors and presentations of patients with clinically driven TVR after DES.Methods: Patients with all lesions treated with a DES in the Dynamic Registry from 2004 to 2006 were analyzed. Included were 2691 patients with 3401 lesions. Patients with and without incident clinically driven TVR at 2 years were compared according to baseline clinical, procedural, and angiographic characteristics and independent predictors of TVR and target lesion revascularization (TLR) were determined by multivariate analysis.
