Background:The optimal duration of dual antiplatelet therapy (DAPT) in patients with diabetes mellitus (DM) admitted with acute coronary syndrome (ACS) and treated with a drug-eluting stent (DES) remains unclear. This is a prespecified substudy from the Randomised Evaluation of short-term DUal antiplatelet therapy in patients with acute Coronary syndromE treated with a new generation DES (REDUCE) trial that was designed to determine the efficacy and safety of short-term versus standard 12 months DAPT in diabetic patients with ACS undergoing percutaneous coronary intervention (PCI) using the COMBO stent.
Methods:In this study we included ACS diabetic patients enroled in the REDUCE trial treated with the COMBO stent and randomly assigned to either 3 or 12 months of DAPT. The primary study endpoint was the composite of all-cause mortality, myocardial infarction (MI), stent thrombosis (ST), stroke, target vessel revascularisation (TVR), and bleeding complications at 12 and 24 months follow-up.Results: A total of 307 diabetic patients were included, of which 162 (52.8%) in the 3 months DAPT group and 145 (47.2%) in the 12 months DAPT group. Patient characteristics, PCI success, and number of stents used were similar in the 3 and 12 months DAPT groups. Occurrence of the primary study endpoint at 12 and 24 months follow-up was comparable between the two groups (3.1 vs. 3.5%, p = 0.865, and 15.8 vs. 14.9%, p = 0.824, respectively). Moreover, the prevalence of the specific clinical outcome parameters (all-cause mortality), MI, ST, stroke, TVR, and bleeding was similar in both study groups.Conclusions: This sub-analysis shows similar clinical outcomes following 3 months DAPT as compared to 12 months DAPT in diabetic patients undergoing PCI for ACS This is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.
The combination of oral anticoagulants with platelet inhibitors has been widely investigated in patients with coronary stenting and concomitant atrial fibrillation. In these patients, default therapy after percutaneous coronary intervention in acute coronary syndrome is clopidogrel plus non–vitamin K antagonist oral anticoagulant, omitting aspirin. However, in view of the high thromboembolic risk associated with acute coronary syndrome and the number of poor metabolizers for clopidogrel, investigation of alternative P2Y12-inhibitors is mandatory. This prospective, multicenter, open-label, registry-based, randomized, controlled trial aims to show the non-inferiority of dabigatran plus ticagrelor versus dabigatran plus clopidogrel in patients on chronic anticoagulants who undergo percutaneous coronary intervention in acute coronary syndrome. The primary end point is major bleeding as defined by the Bleeding Academic Research Consortium bleeding definition. Trial registration number: NL75644.096.21
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
