Aim: To investigate three-year outcomes of patients presenting with nonSTelevation acute coronary syndrome (NSTE-ACS) treated with bioresorbable everolimus-eluting vascular scaffolds (BRS).
Methods and results: The study included a total of 488 consecutive patients, enrolled between May 2012 and December 2013 (median age 65 [56-74], 392 men. 269 patients presented with either NSTEMI or unstable angina at the time of enrolling, 219 patients with stable or silent angina. The primary device-oriented endpoint (Target Lesion Failure, TLF) was defined as a combination of cardiovascular death, target vessel myocardial infarction or clinically driven target lesion revascularization.Among the cardiac risk factors, NSTE-ACS patients were more frequently smokers (P = 0.028), had less frequently dyslipidemia (P = 0.003) and a history of prior PCI (P < 0.01).The median follow-up was 1070[763-1197] days. The three-years incidence of TLF was slightly higher but did not differ significantly between groups (NSTE-ACS: 16.3% vs. 15.9%, p = 0.163). Accordingly, there was no difference in any of the other endpoints.
Conclusion: Treatment of NSTE-ACS with BRS appears to be safe and effective. In this group, risk factors for events during follow up did not differ as compared to the general population.
