Impact of diabetes on clinical outcomes after revascularization with sirolimus‐eluting and biolimus‐eluting stents with biodegradable polymer from the SORT OUT VII trial

OBJECTIVES: In this substudy of the SORT OUT VII trial, the clinical outcomes among patient with diabetes mellitus treated with Orsiro sirolimus-eluting stent (O-SES; Biotronik, Bülach, Switzerland) or Nobori biolimus-eluting stent (N-BES; Terumo, Tokyo, Japan) were compared. BACKGROUND: Diabetes is associated with increased risk of target lesion failure (TLF) after percutaneous coronary intervention. METHODS: In total, 2525 patients were randomized to stent implantation with O-SES (n = 1261, diabetes: n = 236) or N-BES (n = 1264, diabetes: n = 235). The primary endpoint, TLF, was a composite of cardiac death, target-lesion myocardial infarction (MI), or target lesion revascularization (TLR) within 2 years. RESULTS: At 2 year, TLF did not differ between O-SES vs N-BES in diabetic (9.3% vs 9.4%; RR 0.98, 95% CI 0.54-1.78) patients. The individual components of the primary endpoint did not differ among stent type. In diabetics, cardiac death occurred in 3% of O-SES-treated and in 3.8% of N-BES-treated patients (RR 0.77, 95% CI 0.29-2.08), MI occurred in 3.0% of O-SES-treated and in 3.8% of N-BES-treated patients (RR 0.76, 95% CI 0.28-2.06) and TLR occurred in 5,5% of O-SES-treated and in 6.0% of N-BES-treated patients (RR 0.91, 95% CI 0.43-1.95). CONCLUSION: TLF did not differ between O-SES- and N-BES-treated diabetic patients.
