  • Beschreibung: <jats:title>Abstract</jats:title><jats:sec><jats:title>Background</jats:title><jats:p>There are limited data on uninterrupted anticoagulation with direct oral anticoagulants during catheter ablation for atrial fibrillation (<jats:styled-content style="fixed-case">AF</jats:styled-content>), particularly in Japan. We planned a subgroup analysis of the <jats:styled-content style="fixed-case">RE‐CIRCUIT</jats:styled-content> study, comparing the use of uninterrupted dabigatran therapy with warfarin therapy during catheter ablation among the Japanese subgroup and with that in the total population.</jats:p></jats:sec><jats:sec><jats:title>Methods</jats:title><jats:p>The <jats:styled-content style="fixed-case">RE‐CIRCUIT</jats:styled-content> study utilized a prospective, randomized, open‐label, blinded endpoint design, and the primary endpoint was the incidence of major bleeding events (<jats:styled-content style="fixed-case">MBE</jats:styled-content>s). Patients were randomized to uninterrupted dabigatran 150 mg twice daily or warfarin. In this study, we analyzed the results in Japanese patients.</jats:p></jats:sec><jats:sec><jats:title>Results</jats:title><jats:p>Of 704 enrolled patients in the study, 112 Japanese patients were randomized to dabigatran (n = 65) or warfarin (n = 47). <jats:styled-content style="fixed-case">MBE</jats:styled-content>s were experienced by two patients: one in the dabigatran group (1.6%, cardiac tamponade) and one in the warfarin group (2.2%, groin hematoma) (risk difference vs warfarin −0.6%; 95% <jats:styled-content style="fixed-case">CI</jats:styled-content> −5.8, 4.7). Within the Japanese subgroup, there were no thromboembolic events in both groups.</jats:p></jats:sec><jats:sec><jats:title>Conclusion</jats:title><jats:p>While not designed to show statistical difference between two treatment groups, our results from the Japanese subgroup supported those from the overall population. Furthermore, this study provided clinical information regarding <jats:styled-content style="fixed-case">MBE</jats:styled-content>, especially cardiac tamponade, in Japanese patients.</jats:p></jats:sec>
