Abstract
The Cobalt-Chromium Everolimus-Eluting Stent (CoCr-EES) Post-marketing Surveillance (PMS) is a prospective multicenter registry designed to evaluate the safety and efficacy of XIENCE V/PROMUS everolimus-eluting stents in routine clinical practice at 47 centers representative of the clinical environment in Japan. We enrolled 2,010 consecutive patients (2,649 lesions) who underwent PCI using CoCr-EES. Clinical outcomes were evaluated for up to 3 years. Clinical follow-up was available in 1,930 patients (96%) at 3 years. Major adverse cardiovascular events (MACE) occurred in 6.8% of patients, including cardiac death (1.7%), myocardial infarction (1.5%), and clinically driven target lesion revascularization (CD-TLR, 4.2%). Late CD-TLR rate was 0.8% from 1 to 2 years, and 0.5% from 2 to 3 years. Definite or probable stent thrombosis occurred in 7 patients (0.3%) up to 1 year. There was no very late definite or probable stent thrombosis from 1 to 3 years. Significant independent predictors for MACE were hemodialysis, prior coronary intervention, triple-vessel coronary artery disease, and age >70 years. Three-year clinical outcomes from the CoCr-EES PMS demonstrated a low incidence of clinical events. There was no major concern about very late stent thrombosis or late catch-up phenomenon in patients treated with EES in routine clinical practice in Japan.
