The 'all comer' Coroflex Please drug-eluting stent registry in Europe and Asia - an overall and transcontinental assessment of the 10-month major adverse cardiac events.

ABSTRACT

BACKGROUND: Randomized trials assess the potential of a medical device in well defined indications while "all comer studies" reveal the device performance in the real clinical environment. AIMS: This 'all comers' registry assessed the 10-month outcome of the Coroflex(®) Please drug-eluting stent in Europe and Asia by clinically driven major adverse cardiac events. METHODS: The Coroflex(®) Please Registry was an international, prospective, multicenter registry enrolling patients with symptomatic ischemic heart disease. The primary endpoint was clinically driven target lesion revascularization (TLR) at 9 months. Secondary endpoints were technical success, in-hospital outcomes, definite stent thrombosis and major adverse cardiac events (death, myocardial infarction, or TLR) for subgroup analyses. RESULTS: Of the enrolled 1230 patients (63.6 ± 11.2 years, 33.9% diabetics), 339 (27.6%) had an acute coronary syndrome, 148 (12.1%) STEMI and 191 (15.6%) NSTEMI. After 10.5 ± 3.8 months (follow-up rate 92.8%), the target lesion revascularization rate (TLR) was 7.8% overall, 8.3% in STEMI, and 11.3% in NSTEMI patients. Total MACE was 11.1% and significantly higher in ACS with either diabetes mellitus (22.9%, p = 0.017) or age ≥75 years (25.4%, p = 0.026). In European and Asian patients MI rates (5.2% vs 3.1%, p = 0.135) and cardiac death rates (1.6% vs 0.9%, p = 0.414) were similar. The MACE rate was higher in Europe (13.6% vs 4.7%, p < 0.001) driven by a six times higher TLR rate. CONCLUSIONS: TLR and MACE occurred within the range of previously published data. The incidence of MI and cardiac death were not different between Europe and Asia. MACE were higher in Europe driven by target lesion revascularization.
