- AIMS: Patients with atrial fibrillation undergoing coronary intervention are at higher bleeding risk due to the concomitant need for oral anticoagulation and antiplatelet therapy. The RE-DUAL PCI trial demonstrated better safety with dual antithrombotic therapy (DAT: dabigatran 110 or 150 mg bid, clopidogrel or ticagrelor) compared to triple antithrombotic therapy (TAT: warfarin, clopidogrel or ticagrelor, and aspirin). We explored the impact of baseline bleeding risk based on the PRECISE-DAPT score for decision-making regarding DAT vs. TAT.METHODS AND RESULTS: A score ≥25 points qualified high bleeding-risk (HBR). Comparisons were made for the primary safety endpoint ISTH major or clinically relevant non-major bleeding, and the composite efficacy endpoint of death, thromboembolic events, or unplanned revascularization, analyzed by time-to-event analysis. PRECISE-DAPT was available in 2,336/2,725 patients, and 37.9% were HBR. Compared to TAT, DAT with dabigatran 110 mg reduced bleeding risk both in non-HBR (HR 0.42, 95%CI, 0.31-0.57) and HBR (HR 0.70, 95%CI, 0.52-0.94), with a greater magnitude of benefit among non-HBR (Pint=0.02). DAT with dabigatran 150 mg vs. TAT reduced bleeding in non-HBR (HR 0.60, 95%CI, 0.45-0.80), with a trend toward less benefit in HBR patients (HR 0.92, 95%CI, 0.63-1.34, Pint=0.08). Risk of ischaemic events was similar on DAT with dabigatran (both 110 and 150 mg) vs. TAT in non-HBR and HBR patients (Pint=0.45 and Pint=0.56, respectively).CONCLUSIONS: PRECISE-DAPT score appeared useful to identify AF patients undergoing PCI at further increased risk of bleeding complications, and may help clinicians identifying the antithrombotic regimen intensity with the best benefit-risk ratio in an individual patient.

- AIMS: Safety and efficacy of antithrombotic regimens in patients with atrial fibrillation (AF) undergoing percutaneous coronary intervention (PCI) may differ based on clinical presentation. We sought to comparing double vs. triple antithrombotic therapy (DAT vs TAT) in AF patients with or without acute coronary syndrome (ACS) undergoing PCI.METHODS AND RESULTS: A systematic review and meta-analysis was performed using PubMed to search for non-vitamin K antagonist oral anticoagulant (NOAC)-based randomized clinical trials. Data on subgroups of ACS or elective PCI were obtained by published reports or trial investigators. A total of 10,193 patients from 4 NOAC trials were analyzed, of whom 5,675 presenting with ACS (DAT = 3,063 vs. TAT = 2,612) and 4,518 with SCAD (DAT = 2,421 vs. TAT = 2,097). The primary safety endpoint of ISTH major bleeding or CRNMB was reduced with DAT compared with TAT in both ACS (12.2% vs 19.4%; RR 0.63, 95% CI 0.56-0.71; p < 0.0001; I2=0%) and SCAD (14.6% vs 22.0%; RR 0.68, 95% CI 0.55-0.85; p = 0.0008; I2=66%), without interaction (p-int = 0.54). Findings were consistent for secondary bleeding endpoints, including intracranial Haemorrhage. In both subgroups, there was no difference between DAT and TAT for all-cause death, major adverse cardiovascular events, or stroke. Myocardial infarction and stent thrombosis were numerically higher with DAT vs. TAT consistently in ACS and SCAD (p-int = 0.60 and 0.86 respectively). Findings were confirmed by multiple sensitivity analyses, including a separate analysis on dabigatran regimens and a restriction to PCI population.CONCLUSIONS: DAT, compared with TAT, is associated with lower bleeding risks, including intracranial Haemorrhage, and a small non-significant excess of cardiac ischaemic events in both patients with or without ACS.
