| アブストラクト | BACKGROUND: Few large-scale, real-world studies have compared the efficacy and safety of non-antivitamin K anticoagulants (NOACs) with that of warfarin in catheter ablation (CA) for atrial fibrillation (AF). METHODS: This retrospective, cross-sectional study used a nationwide administrative claims database, to compare complication-incidence rates following CA for AF between NOAC-treated patients and warfarin-treated matched cohorts in the real-world. Among the 32,797,540 records between June 2011 and August 2020 from 426 hospitals, 41,347 patients (38,065 on NOACs and 3,282 on Warfarin) were considered eligible. After performing propensity matching, 6,564 patients (3,282 per group) were analyzed. RESULTS: The overall complication incidence was significantly lower in the NOACs group than in the warfarin group (2.3 % vs. 4.0 %; P < 0.001, odds ratio [OR]: 0.55, 95 % confidence interval [CI]: 0.41-0.74). Although no significant differences in the incidence of cardiac tamponade (1.0 % vs. 1.1 %; P = 0.90, OR: 0.97, 95 % CI: 0.60-1.56) and major bleeding (0.6 % vs. 0.7 %; P = 0.54, OR: 0.83, 95 % CI: 0.44-1.52) were noted, blood transfusion requirements (0.6 % vs. 1.2 %; P = 0.02, OR: 0.52, 95 % CI: 0.30-0.88) and vascular complications (0.2 % vs. 0.5 %; P = 0.02, OR: 0.33, 95 % CI: 0.12-0.79) were significantly lower in the NOACs group than in the warfarin group. Furthermore, the thromboembolic event incidence was significantly lower in the NOACs group than in the warfarin group (0.5 % vs. 1.2 %; P < 0.001, OR: 0.36, 95 % CI: 0.19-0.64). CONCLUSIONS: NOACs should be considered as a first-line therapy for periprocedural anticoagulation in patients undergoing CA for AF. |
