Therefore, we evaluated 3-year clinical outcomes after EES implantations in a real-world setting at 47 Japanese sites using the EES Japan PMS database.
Methods
Subjects and Follow-upCoCr-EES PMS Japan is a prospective multicenter registry enrolling 2,000 patients who received CoCr-EES. The study was designed to evaluate the safety and efficacy of the CoCr-EES in routine clinical practice shortly after the launch of ate stent thrombosis and late in-stent restenosis are the 2 major limitations of first-generation drug-eluting stents (DES). 1,2 Second-generation DES are associated with significantly lower in-stent restenosis rate and lower rate of late stent thrombosis as compared with first-generation DES. 3-6 Therefore, second-generation DES are used currently as the first-line coronary stents in routine clinical practice. Clinical outcomes of first-generation DES, such as sirolimusand paclitaxel-eluting stents, in earlier Japanese post-marketing surveillance studies (PMS) have been published previously, 7-9 but long-term clinical outcomes for second-generation DES, such as cobalt-chromium everolimus-eluting stents (CoCr-
