Abstract

Background:Data regarding the long-term outcomes of a large patient population with multivessel coronary artery disease (MV-CAD) after complete revascularization (CR) and incomplete revascularization (IR) with drug-eluting stent (DES) implantation are controversial. The objective of this study was to evaluate differences between the clinical outcomes of CR and IR in such patients.

Methods and Results:A total of 1,502 patients with MV-CAD who received DES between April 2005 and August 2016 were enrolled in this study after propensity score matching. The CR group had 751 patients with 1,368 stents implanted in 1,215 lesions, and the IR group had 751 patients with 1,077 stents implanted in 948 lesions. The CR group had a similar rate of in-hospital major adverse cardiovascular events to the IR group (1.9% vs. 1.6%, P=0.844). Follow-up angiography at 9 months showed no significant difference between the 2 groups for restenosis. The CR group had a higher cardiovascular event-free survival rate than the IR group during a mean follow-up period of 71±62 months (81.8% vs. 72.0%, P<0.001). Kaplan-Meier survival analysis also showed better results in the CR group than in the IR group.

Conclusions:Angiographic CR was associated with more favorable long-term cardiovascular outcomes than angiographic IR in patients with MV-CAD after DES implantation.
