BACKGROUND.: Older patients and diabetes mellitus (DM) are rapidly increasing in Western world populations. The treatment of coronary artery disease in these patients is challenging because they are complex and at high risk. Performance of the two widely used drug-eluting stents (DES), i.e. sirolimus- (SES) and paclitaxel-eluting stent (PES), is understudied in this subset. AIM.: We aimed to explore the impact of the first generation DES choice on mid term outcome in a large and unselected population of diabetic patients older than 65 years METHODS AND RESULTS.: From a multicenter registry of 2429 diabetic patients treated with sirolimus- (SES) or paclitaxel-eluting stent (PES), 1417 patients ò65 years old were analyzed overall and separately for groups aged 65-74 (67%) and ò75 (33%) years old. SES (55%) were compared to PES (45%) in terms of major adverse cardiac events, including all-cause death, myocardial infarction (MI) and target lesion revascularization (TLR) throughout 1-to-5-year follow-up (median time 24 months). We failed to find at the unadjusted and adjusted analyses, a statistically differences in term of outcome between the two DES, both in the overall cohort and in the two different aged subgroups, also regardless of the insulin treatment. CONCLUSIONS.: In this real-life multicenter registry, PES and SES showed a comparable safety and efficacy profile in diabetic patients older than 65 years throughout 1 to 5 year of follow-up period.

Abstract

BACKGROUND.: Older patients and diabetes mellitus (DM) are rapidly increasing in Western world populations. The treatment of coronary artery disease in these patients is challenging because they are complex and at high risk. Performance of the two widely used drug-eluting stents (DES), i.e. sirolimus- (SES) and paclitaxel-eluting stent (PES), is understudied in this subset. AIM.: We aimed to explore the impact of the first generation DES choice on mid term outcome in a large and unselected population of diabetic patients older than 65 years METHODS AND RESULTS.: From a multicenter registry of 2429 diabetic patients treated with sirolimus- (SES) or paclitaxel-eluting stent (PES), 1417 patients ò65 years old were analyzed overall and separately for groups aged 65-74 (67%) and ò75 (33%) years old. SES (55%) were compared to PES (45%) in terms of major adverse cardiac events, including all-cause death, myocardial infarction (MI) and target lesion revascularization (TLR) throughout 1-to-5-year follow-up (median time 24 months). We failed to find at the unadjusted and adjusted analyses, a statistically differences in term of outcome between the two DES, both in the overall cohort and in the two different aged subgroups, also regardless of the insulin treatment. CONCLUSIONS.: In this real-life multicenter registry, PES and SES showed a comparable safety and efficacy profile in diabetic patients older than 65 years throughout 1 to 5 year of follow-up period.
