Safety and effectiveness of zotarolimus-eluting stents for percutaneous coronary intervention: a systematic review.

Drug-eluting stents revolutionized the treatment of coronary artery disease with vastly improved outcomes compared with bare metal stents. As stent technology has evolved, a wide variety of antiproliferative drugs have been developed to prevent stent restenosis and stent thrombosis. The Resolute stent system (Medtronic, CA, USA) elutes zotarolimus from a multipolymer blend to prevent early and late stent-related complications. The Resolute stents have evolved from the initial Resolute stent, to the Resolute Integrity™ and most recently, the Resolute Onyx™. These stents have been studied across a wide range of patients and coronary syndromes. They compare similarly in performance to their contemporary second generation stents. We present a review of the major trials involving these zotarolimus-eluting stents.
