About
The purpose of this study is to evaluate the incidence of late incomplete stent apposition (ISA) and un-coverage by optical coherence tomography (OCT) following everolimus-eluting stent (EES) with bioabsorbable polymer (SYNERGY™, Boston Scientific,Nattick, MA, USA) versus zotarolimus-eluting stent (ZES) with permanent polymer(Resolute Onyx™, Medtronic, Santa Rosa, CA, USA) implantation in patients with AMI at 12 months.
Full description
It has been known that persistence of polymer may affect the late/very late safety and efficacy of drug eluting stent (DES) although polymer provides a reservoir for programmed drug release. Newer durable polymers may have enhanced biocompatibility and seem to be associated with improved clinical outcomes. However, they have still been incriminated in the occurrence of inflammation, neo-atherosclerosis, and thrombosis. Therefore, the investigators will evaluate the vascular tissue reaction after different kinds of DES implantation under the high thrombogenic circumstance of acute myocardial infarction (AMI).
