OBJECTIVES: We sought to investigate whether the previously reported midterm clinical benefit of planned sirolimus-eluting stent (SES) implantation in patients with ST-segment elevation myocardial infarction (STEMI) was maintained over a 24-month time period. Moreover, the distribution of clinical events in relation to thienopyridine discontinuation was thoroughly investigated. BACKGROUND: No randomized data are currently available on the safety/benefit profile of SES in this subset of patients beyond 12 months. METHODS:Between March 2003 and April 2004, 175 patients with STEMI were randomly allocated to tirofiban infusion followed by SES or abciximab plus bare-metal stent (BMS). Complete follow-up information up to 720 days was available for all patients. RESULTS: The cumulative incidence of death, myocardial infarction (MI), or target vessel revascularization (TVR) remained lower in the tirofiban-SES compared with the abciximab-BMS group at 2 years (24.2% vs. 38.6%, respectively; hazard ratio [HR] 0.56 [95% confidence interval (CI) 0.33 to 0.98]; p = 0.038). The composite of death/MI was similar in the tirofiban-SES (16.1%) and the abciximab-BMS groups (20.5%, HR 0.77 [95% CI 0.38 to 1.55]; p = 0.43) while the need for TVR was markedly reduced (9.8% vs. 25.5%, respectively; HR 0.34 [95% CI 0.16 to 0.77]; p = 0.01) in the tirofiban-SES arm. The rate of confirmed, probable, or possible stent thrombosis did not differ in the 2 groups, nor the incidence of death/MI after thienopyridine discontinuation. CONCLUSIONS: The midterm clinical benefit of planned SES implantation assisted by tirofiban infusion in STEMI patients was mainly carried over after 2 years with no overall excess of late adverse events after thienopyridine discontinuation.
