Risk Factors for Restenosis after Percutaneous Coronary Intervention with Sirolimus- and Paclitaxel-eluting Stents

Abstract

CI, 1.65 7.27 ; P 0.01 were independent risk factors for target lesion revascularization TLR with SES. In contrast, no independent risk factors for restenosis and TLR were found for lesions treated with PES. The rate of TLR was signi cantly higher in patients on hemodialysis or in those with long lesions in the SES group hemodialysis, 30.4 vs. 11.1 , P 0.02 ; long lesions, 13.2 vs. 4.4 , P 0.01 ; for SES vs. PES, respectively . Rates of restenosis and TLR were signi cantly higher in patients with bent lesions in the SES group restenosis, 30.8 vs. 15.6 , P 0.01 ; TLR, 20.0 vs. 5.8 , P 0.01 ; for SES and PES, respectively . Most clinical studies have described better angiographic results for SES compared to PES. However, PES might result in better clinical outcomes than SES for patients on hemodialysis or for those with long or bent lesions.
