Background |
There is an ongoing debate on the optimal drug-eluting stent (DES) in diabetic patients with coronary artery disease. We addressed this issue by making a synthesis of the available evidence on the relative long-term efficacy and safety of sirolimus-eluting stent (SES) and paclitaxel-eluting stent (PES) in these patients.
Methods |
Individual patient data were analyzed from 6 randomized trials specifically designed to compare SES with PES in diabetic patients. In total, 1183 patients were followed up for a median of 3.9 years (25th, 75th percentiles 3.4-4.5 years). The primary efficacy end point was target lesion revascularization (TLR). The composite of death and myocardial infarction (MI) was the primary safety end point. Stent thrombosis was a secondary end point. Overall hazard ratios (HRs) with 95% CIs were calculated as summary estimates.
Results |
No significant heterogeneity was seen across the 6 randomized trials for all analyzed events. Sirolimus-eluting stent was associated with a significant reduction in the risk of TLR (HR 0.65 [0.47-0.91], P = .01). No significant differences were observed regarding the risk of death or MI (HR 1.04 [0.74-1.45], P = .83) and stent thrombosis (HR 1.00 [0.31-3.30], P = .67). Mortality was also not affected by the type of DES (HR 0.95 [0.65-1.39], P = .79).
Conclusions |
In diabetic patients with coronary artery disease, SES leads to a sustained reduction in the risk of TLR compared with PES. Both these DES types are, however, comparable with respect to the risk of stent thrombosis, MI, or death over long-term follow-up.
