Clinical Impact of Lesion Complexity on 2-Year Outcomes After Zotarolimus-Eluting Stents Implantation.

ABSTRACT:

Background

The clinical efficacy and safety of second-generation drug-eluting stents in complex percutaneous coronary interventions (PCIs) are not well established.

Objectives

The clinical influence of the lesion complexity after PCI with zotarolimus-eluting stents (ZES) was evaluated.

Methods

From a prospective multicenter observational study, a total of 926 patients that underwent successful PCIs with ZES were included. Complex PCIs were defined as patients with ≥3 lesions treated, 3 vessels treated, severe calcified lesions, bifurcated lesions with 2 stents implanted, left main disease, chronic total occlusion lesions, and/or diffuse long (total stent length ≥60 mm) lesions and were compared to the noncomplex group. The primary outcome was incidence of target lesio
