One-Year Outcome From an All-Comers Population of Patients With ST-Segment Elevation Myocardial Infarction Treated With Biolimus-Eluting Stent With Biodegradable Polymer

Objectives To evaluate the performance of biolimus-eluting stent (BES) in patients with ST-elevation myocardial infarction (STEMI) undergoing percutaneous coronary intervention (PCI) in a real world clinical scenario. Background Randomized studies suggest that the BES with biodegradable polymer is more effective and safe than early generation coronary stents in patients with STEMI. Methods We included all consecutive STEMI patients undergoing PCI in this prospective, multicenter registry. The primary endpoint of the study was the rate of major adverse cardiac events (MACE), a composite of cardiac death, recurrent myocardial infarction and ischemia-driven target vessel revascularization at 1-year follow-up. Results Between June and December 2012 we enrolled 311 STEMI patients. The primary endpoint occurred in 3.2% (95% confidence interval: 1.6–5.8) of patients: cardiac death, re-infarction, and ischemia-driven TVR occurred in 2.3%, 1.3%, and 0.6% of patients, respectively. One-year MACE-free survival was 96.8% ± 1.0%. Conclusions In a real-world cohort of STEMI patients undergoing PCI, the use of BES is associated with good 1-year clinical outcome. These results confirm and expand previous findings showing the efficacy and safety of BES in the setting of randomized trials. © 2014 Wiley Periodicals, Inc.
