['Zotarolimus-eluting stents (ZESs) have been shown to be safe and effective in randomised trials. We sought to report the clinical outcomes after implantation of ZES in real-world clinical practice.', 'ZES have been approved for clinical use in Singapore since April 2005. Until December 31, 2007, a total of 219 patients had undergone implantation of ZES. After excluding 11 foreign patients with whom contact was lost, 208 patients (246 lesions, 305 stents) formed the study cohort. A high-proportion of diabetic patients (n=90, 43.3%) was included. Recommended dual antiplatelet therapy was at least 3 months (n=147) for patients treated before or 12 months (n=61) after January 2007. As of January 2008, the median follow-up duration was 19 months (range: 1 to 33 months). There were 10 (4.8%) deaths, including 7 (3.4%) cardiac deaths. Myocardial infarction occurred in 11 (5.3%) patients. The numbers of patients requiring target vessel revascularisation and target lesion revascularisation were 10 (4.8%) and 5 (2.4%) respectively. Using the ARC definition, there were two cases of definite stent thrombosis on days 7 and 17, and one case of probable stent thrombosis on day 15.'] Are long-term safety and efficacy observed after implantation of Zotarolimus-Eluting stent in real-world clinical practice?
