Background: Diabetes has been well recognized as a strong predictor of adverse outcomes after percutaneous coronary intervention (PCI), but studies in the era of drug-eluting stents and potent P2Y12 inhibitors have shown conflicting results. We assessed ischemic and bleeding outcomes after contemporary PCI according to diabetic status.

Method(s): We studied 15,957 patients in the GLOBAL LEADERS study with known baseline diabetic status. The primary endpoint was all-cause death or new Q-wave myocardial infarction at 2 years. The secondary safety endpoint was major bleeding defined as Bleeding Academic Research Consortium (BARC) type 3 or 5.

Result(s): A quarter of the study cohort had diabetes (4,038 of 15,957), and these patients had a significantly higher risk for the primary endpoint at 2 years compared with those without diabetes (adjusted hazard ratio [HR]: 1.36; 95% confidence interval [CI]: 1.14 to 1.61). The difference was driven by a significantly higher risk for all-cause mortality at 2 years in patients with diabetes (adjusted HR: 1.44; 95% CI: 1.18 to 1.75). The risk for BARC type 3 or 5 bleeding was comparable between the 2 groups (adjusted HR: 1.18; 95% CI: 0.92 to 1.50). The antiplatelet strategy (experimental vs. reference strategy) had no significant effect on the rates of the primary endpoint and secondary safety endpoint at 2 years in patients with and without diabetes.

​Conclusion(s): Patients with diabetes had a higher risk for ischemic events after PCI than those without diabetes, while bleeding risk was comparable. The outcomes of patients with diabetes following PCI were not affected by the 2 different antiplatelet strategies. Categories: CORONARY: Pharmacology/PharmacotherapyCopyright © 2019
