Abstract
Objectives: This study sought to compare clinical outcomes and angiographic findings using the Resolute zotarolimus-eluting stent (R-ZES) (Medtronic, Santa Rosa, California) versus the Taxus Liberte paclitaxel-eluting stent (PES) (Boston Scientific, Natick, Massachusetts) in an all-comer Chinese population. Background: Concerns regarding restenosis risk led to new-generation drug-eluting stents (DES) designed for use in patients with complex clinical or lesion characteristics. In-stent late lumen loss (LLL) is a measure of restenosis risk. Methods: Patients with an indication for treatment with a DES were randomized in a 1:1 ratio to placement of at least 1 R-ZES or PES with minimal exclusions. The primary endpoint was angiographic in-stent LLL at 9 months post-procedure. Clinical endpoints at 12 months are compared between the 2 stents. Results: A total of 198 patients received a R-ZES, and 202 patients received a PES. Most patients were male; 25.8% and 29.2% of R-ZES and PES patients, respectively, had diabetes. Over 70% of lesions in both cohorts were American College of Cardiology/American Heart Association lesion classification Type B2 and C (B2/C). In-stent LLL was 0.16 ± 0.38 mm for R-ZES and 0.33 ± 0.52 mm for PES at 9 months (p < 0.001; 95% confidence interval [CI]: -0.26 to -0.08). The rates of clinically driven target lesion revascularization were 1.5% for R-ZES and 7.0% for PES (p = 0.011). The rate of target lesion failure was 5.6% for R-ZES and 11% for PES (p = 0.068). Conclusions: In an all-comers Chinese population, 9-month in-stent LLL was significantly less with R-ZES compared with PES, which was reflected in lower revascularization rates at 12 months for the R-ZES patients. Results are consistent with previous clinical trials of the R-ZES in all-comer populations.
