There is ongoing debate on the optimal drug-eluting stent (DES) in diabetic patients with coronary artery disease. Biodegradable polymer drug-eluting stents (BP-DES) may potentially improve clinical outcomes in these high-risk patients. We sought to compare long-term outcomes in patients with diabetes treated with biodegradable polymer DES vs. durable polymer sirolimus-eluting stents (SES).We pooled individual patient-level data from 3 randomized clinical trials (ISAR-TEST 3, ISAR-TEST 4 and LEADERS) comparing biodegradable polymer DES with durable polymer SES. Clinical outcomes out to 4 years were assessed. The primary end point was the composite of cardiac death, myocardial infarction and target-lesion revascularization. Secondary end points were target lesion revascularization and definite or probable stent thrombosis.Of 1094 patients with diabetes included in the present analysis, 657 received biodegradable polymer DES and 437 durable polymer SES. At 4 years, the incidence of the primary end point was similar with BP-DES versus SES (hazard ratio = 0.95, 95% CI = 0.74-1.21, P = 0.67). Target lesion revascularization was also comparable between the groups (hazard ratio = 0.89, 95% CI = 0.65-1.22, P = 0.47). Definite or probable stent thrombosis was significantly reduced among patients treated with BP-DES (hazard ratio = 0.52, 95% CI = 0.28-0.96, P = 0.04), a difference driven by significantly lower stent thrombosis rates with BP-DES between 1 and 4 years (hazard ratio = 0.15, 95% CI = 0.03-0.70, P = 0.02).In patients with diabetes, biodegradable polymer DES, compared to durable polymer SES, were associated with comparable overall clinical outcomes during follow-up to 4 years. Rates of stent thrombosis were significantly lower with BP-DES.     «
