Long-term follow-up of second-generation everolimus-eluting stents versus first-generation sirolimus-eluting stents in acute myocardial infarction: three-year results of the XAMI trial

Abstract Evaluation of the long-term safety and efficacy of second-generation everolimus-eluting stents (EES) versus first-generation sirolimus-eluting stents (SES) in acute myocardial infarction (AMI) patients. Six hundred and twenty-five patients were randomised (2:1) to EES or SES in the multicentre XAMI (XienceV stent vs. Cypher stent in Primary PCI for Acute Myocardial Infarction) trial. The primary endpoint was cardiac death, non-fatal AMI or any target vessel revascularisation (TVR) at one year, with a planned follow-up of three years. At three-year follow-up, the primary endpoint was 8.0% for EES and 10.5% for SES (p=0.30). Cardiac death was low and comparable in both groups (EES: 2.5% versus SES: 2.7%; p=0.86), as was definite/probable stent thrombosis (EES: 2.3% versus SES 3.2%; p=0.60). The event rate at three years in this all-comer, randomised, multicentre AMI trial was low, including stent thrombosis, with no significant difference between first- and second-generation DES.
