Abstract:
Objective:To evaluate the effectiveness and safety of anticoagulant therapy with rivaroxaban in atrial fibrillation( AF) pa-tients after radiofrequency catheter ablation( RFCA) . Methods:A retrospective analysis was performed in the study. Totally 141 AF pa-tients with RFCA in our hospital were enrolled from January 2014 to October 2015. The patients were divided into rivaroxaban group(70 patients)and warfarin group (71 patients). In rivaroxaban group,rivaroxaban(10 mg, po,qd)was given for at least 3 months after RFCA. In warfarin group,low molecular heparin (100 IU·kg-1,ih) was given before RFCA, and standard dose of warfarin (3-5 mg,po,qd) was given for at least 3 months by adjusting the INR within the range of 2. 0-3. 0 after RFCA as bridging therapy. The death rate, throm-boem bolism events and bleeding events between the groups were evaluated and companed groups. Results: There were no significant differences in baseline characteristics between the groups except the diastolic pressure. There were no significant differences in the death and thromboembolism events(transient cerebral ischemia , ischemic encephalopathy, 2/70 vs 4/71,P>0. 05)between the groups. There were no TIMI major bleeding events in both groups. There were no significant differences in minor bleeding events between the groups (3/70 vs 4/71,P>0. 05). Conclusion: Compared with those of warfarin,the effectiveness and safety of rivaroxaban show the similar effect in AF patients after RFCA. Rivaroxaban can be safely and effectively used in AF patients with low or middle risk of thromboembo-lism after RFCA.
