Abstract

The purpose of the present study was to evaluate the 3-year clinical outcomes after percutaneous coronary intervention with sirolimus-eluting stents in patients with insulin-treated diabetes mellitus (DM-insulin) and those with non-insulin-treated DM (DM-non-insulin) compared to patients without DM. Of 10,778 consecutive patients treated exclusively with sirolimus-eluting stents in the j-Cypher registry, we identified 996 patients with DM-insulin, 3,404 with DM-non-insulin, and 6,378 without DM. Compared to the non-DM group, the adjusted risk of a serious cardiovascular event (composite of all-cause death, myocardial infarction, and stroke) was significantly greater in the DM-insulin group (hazard ratio 1.12, 95% confidence interval [CI] 1.03 to 1.23; p = 0.01), but not in the DM-non-insulin group (hazard ratio 1.02, 95% CI 0.96 to 1.09; p = 0.47). The adjusted risk of target lesion revascularization was significantly greater in both the DM-insulin group (odds ratio 1.52, 95% CI 1.19 to 1.92; p = 0.0006) and the DM-non-insulin group (odds ratio 1.24, 95% CI 1.05 to 1.45; p = 0.009). In conclusion, a diabetes-associated excess risk of target lesion revascularization was found, regardless of insulin use in this large, real-world study of Japanese patients with sirolimus-eluting stent implantation. However, regarding serious cardiovascular events, an excess risk was seen only in the DM-insulin group. The risk of serious cardiovascular events was similar between the DM-non-insulin and non-DM groups.
