Aims Everolimus-eluting stents (EES) were superior to sirolimus-eluting stents (SES) in a dedicated myocardial infarction trial, a finding that was not observed in trials with low percentages of ST-elevation myocardial infarction (STEMI). Therefore, this study sought to investigate the influence of clinical presentation on outcome after EES and SES implantation. Methods A pooled population of 1602 randomised patients was formed from XAMI (acute MI trial) and APPENDIXAMI (all-comer trial). Primary outcome was cardiac mortality, MI and target vessel revascularisation at 2 years. Secondary endpoints included definite/probable stent thrombosis (ST). Adjustment was done using Cox regression. Results In total, 902 EES and 700 SES patientswere included, of which 44%STEMI patients (EES 455; SES 257) and 56% without STEMI (EES 447; SES 443). In the pooled population, EES and SES showed similar outcomes during followup. Moreover, no differences in the endpoints were observed after stratification according to presentation. Although a trend toward reduced early definite/probable ST was observed in EES compared with SES in STEMI patients, long-term ST rates were low and comparable. Conclusions EES and SES showed a similar outcome during 2-year follow-up, regardless of clinical presentation. Longterm safety was excellent for both devices, despite wide inclusion criteria and a large sub-population of STEMI patients.
