Long-term outcomes after Resolute zotarolimus-eluting stent implantation in patients with ST-segment elevation acute myocardial infarction: insights from the RESOLUTE All Corners Trial and the RESOLUTE Global Clinical Trial Program
Abstrakt
Aims: We examined long-term outcomes after implantation of the Resolute zotarolimus-eluting stent (R-ZES) in ST-segment elevation acute myocardial infarction (STEMI) patients. Methods and results: We compared long-term outcomes of STEMI patients undergoing primary angio-plasty <12 hours from syniptom onset who were randomised to the R-ZES (n=122) or the everolimuseluting stent (EES, n=158) in the RESOLUTE All Comers Trial after propensity score adjustment.
The five-year cumulative incidence of target lesion failure (TLF) was 7.6% versus 10.4% among patients treated with R-ZES versus EES, respectively, (adjusted p=0.304), and comprised clinically driven target lesion revascularisation (TLR, 2.5% versus 2.0%, adjusted p=0.766) and cardiac death/target vessel MI (5.1% versus 9.1%, adjusted p=0.123). The five-year cumulative incidence of stent thrombosis was 0.8% for R-ZES patients versus 1.3% for EES patients (adjusted p=0.868).
In the RESOLUTE Global Clinical Trial Program, excluding RESOLUTE All Comers, the three-year cumulative incidence of TLF with R-ZES was 9.8% and comprised 7.0% clinically driven TLR and 4.5% cardiac death/target vessel MI. Conclusions: Patients with STEMI who received R-ZES had excellent long-term clinical outcomes which were similar to those of patients who received EES.
