Abstract | BACKGROUND: METHODS: RESULTS: Overall 1920 of 6203 (31.0%) of new-onset AF had vascular disease. In patients with vascular disease, 62.2% of those were treated with direct oral anticoagulants (DOACs) and 23.4% with warfarin. Dual therapy and triple therapy were used in 36.9% and 4.9%, respectively. Vascular disease patients had increased risk of MACNE (adjusted hazard ratio [aHR] 1.83 [95%CIs 1.32-2.55]), but not major bleeding (aHR 1.24 [0.95-1.63]). Among patients with vascular disease, relative to those on warfarin, those treated with DOACs had similar risk for MACNE (aHR 1.20 [0.77-1.87]) but lower risks for bleeding, although it did not reach statistical significance (aHR 0.70 [0.43-1.15]). Concomitant antiplatelet therapy was associated with higher bleeding (aHR 2.27 [1.38-3.73]) with no apparent reduction in MACNE (aHR 1.50 [1.00-2.25]). CONCLUSIONS: Most patients with AF and vascular disease were managed with oral anticoagulation. About half of them were also treated with concomitant antiplatelet therapy, which was associated with increased risk of bleeding, without evidence of improved cardiovascular outcomes.
