SERY was the first large-scale clinical trial of YINYI polymer-free paclitaxel-eluting coronary stent after it was launched in 2008. As a study focused on polymer-free DES, SERY had a largest enrolled number in the world range at that time. There were 27 sites enrolled 1045 patients, and 1713 YINYI were implanted. The primary and secondary endpoints had been reported successively in GW-ICC during 2010-2012, and the results were exciting.
ju111net手机版 Polymer-free DES accelerates the endothelialization on the basis of lower restenosis. There is no late catch-up or late stent thrombosis while durable polymer DES has. SERY trial demonstrated YINYI polymer-free PES has DES's efficacy and BMS's safety.
