Abstract

Background and Purpose- The optimal antithrombotic strategy to balance thromboembolic and bleeding events, especially acute stroke, for patients with atrial fibrillation following coronary stenting remains a matter of debate. We conducted a network meta-analysis to identify the antithrombotic regimen associated with the lowest rate of bleeding and thromboembolic events in atrial fibrillation after coronary stenting. Methods- PubMed, Scopus, and Cochrane Central were searched for randomized controlled trials and observational studies of patients with atrial fibrillation after coronary stenting. The outcomes of interest were stroke, myocardial infarction, major adverse cardiac events, mortality, and major bleeding. A network meta-analysis was performed comparing the available antithrombotic regimens in the literature. Results- Three randomized and 15 observational studies were included, with a total of 23 478 participants. Median follow-up was 2 years. Network meta-analysis demonstrated that vitamin K antagonist plus single antiplatelet therapy or direct-acting oral anticoagulant plus single antiplatelet therapy were the most effective regimens in preventing stroke. Direct-acting oral anticoagulant regimens were associated with lower major bleeding rates than vitamin K antagonist regimens. Regimens with dual antiplatelet therapy were associated with lower rates of myocardial infarction. Vitamin K antagonist plus dual antiplatelet therapy was associated with a lower mortality and low-dose direct-acting oral anticoagulants with decreased major cardiovascular adverse events. Conclusions- Direct-acting oral anticoagulant regimens were associated with less major bleeding and major cardiovascular adverse events, but vitamin K antagonists were associated with decreased mortality and stroke. These results suggest that the decision of antithrombotic therapy in patients with atrial fibrillation after percutaneous coronary intervention needs to be individualized.
