Propensity score-matched lesion-based comparison of mid-term angiographic outcomes of TAXUS Liberté with Cypher Bx Velocity stents for de novo native coronary stenosis and in patients with diabetes.

Objective: We sought to perform a propensity score-matched lesion-based comparison of mid-term angiographic outcomes of sirolimus- (SES, Cypher Bx Velocity) and paclitaxel- (PES, TAXUS Liberté, the 2nd-generation TAXUS) eluting stents to treat de novo coronary stenosis and, particularly, in patients with diabetes mellitus (DM) in a daily practice environment.

Methods: The present study was a non-randomized, retrospective, lesion-based, single center study that included 1,287 de novo native coronary stenosis cases after successful SES or PES placement between February 2007 and April 2011. The primary endpoint was angiographic-based binary in-stent restenosis (% diameter stenosis >50 at secondary angiogram) within 550 days of placement.
