| 概要 | INTRODUCTION:Whether the risk-benefit profile of once-daily versus twice-daily direct oral anticoagulants (DOAC) differs after atrial fibrillation(AF)-associated ischemic stroke is unclear. We explored this in a post-hoc analysis of ELAN trial data (NCT03148457).PATIENTS AND METHODS:We compared the risk of the primary outcome (recurrent ischemic stroke, systemic embolism, intracranial hemorrhage (ICH), major extracranial bleeding, vascular death) from treatment initiation to the trial's 90-day follow-up in participants treated with once-daily or twice-daily DOAC after AF-associated stroke using Firth's logistic and Cox proportional hazards regression in unadjusted, inverse-probability-of-treatment-weighted and augmented-inverse-probability-weighted models to address confounding. Secondary outcomes were the primary outcome components and non-major bleeding. We calculated the net clinical benefit (NCB) of twice-daily over once-daily DOAC by subtracting the weighted rate of excess bleeding attributable to twice-daily DOAC from the rate of excess ischemic events possibly prevented by twice-daily DOAC.RESULTS:We analyzed 1890/2013 (94%) participants (median age 77 years, 45% female), of whom 384 (20%) received once-daily and 1506 (80%) twice-daily DOAC. The primary outcome occurred in 64 (3.4%) participants, and did not differ between DOAC types in logistic (ORunadjusted 0.89 (95% CI 0.50-1.66); ORweighted 1.34 (0.71-2.79); ORaugmented 1.45 (0.81-3.21); twice-daily vs once-daily DOAC) nor in Cox models. We identified no clear differences in any secondary outcome. NCB analysis revealed a near-neutral net effect of twice-daily versus once-daily DOAC (+0.28 to +0.67 weighted events possibly prevented/100 person-months for ICH weights 1.5-3.3).DISCUSSION AND CONCLUSION:The risk-benefit profile of once-daily versus twice-daily DOAC after AF-associated ischemic stroke does not seem to differ. |
