N2 - AIMS: Recently, three randomized trials reported that dual antithrombotic treatments (DATs) including non-vitamin K antagonist oral anticoagulants (NOACs) and a P2Y12 inhibitor without aspirin were associated with significantly less bleeding than vitamin K antagonist (VKA)-based triple antithrombotic therapy (TAT) in atrial fibrillation (AF) patients with acute coronary syndrome (ACS) or undergoing percutaneous coronary intervention (PCI). We conducted an analysis of pooled data from these trials. METHODS AND RESULTS: A meta-analysis of the PIONEER AF-PCI, RE-DUAL PCI, and AUGUSTUS trials considering major bleeding [International Society on Thrombosis and Haemostasis (ISTH) and Thrombolysis in Myocardial Infarction], clinically relevant non-major bleeding, all-cause/cardiovascular death, stroke, myocardial infarction (MI), and stent thrombosis. Treatment effect is reported as odds ratio (OR) and 95% confidence interval. Among 9463 patients (53% with ACS), DAT regimens were associated with significantly less bleeding than TAT (OR 0.598, 0.491 -0.727; P < 0.001 for ISTH major bleeding), as were NOAC-based vs. VKA-based regimens (OR 0.577, 0.477 -0.698; P < 0.001). Stroke and mortality rates were similar, but there was statistically non-significant trend towards greater risk of MI (OR 1.211, 0.955 -1.535; P = 0.115) and significantly higher risk for stent thrombosis (OR 1.672, 1.022 -2.733, P = 0.041) with DAT vs. TAT (but not NOAC- vs. VKA-based regimens). This was mainly driven by Dabigatran 110 mg; the trends were lower with full-dose NOAC or Rivaroxaban 15 mg-based DATs. CONCLUSION: Our findings support the use of full-dose NOAC (Apixaban 5 mg, Dabigatran 150 mg) or Rivaroxaban 15 mg-based treatments in most AF patients with ACS or undergoing PCI. Notwithstanding the better safety of DAT, an initial course of NOAC-based TAT may be desirable in most AF patients.
