Rhythm versus rate control strategies regarding anticoagulant use in elderly non-valvular atrial fibrillation patients: Subanalysis of the ANAFIE (All Nippon AF In the Elderly) Registry
2020
Abstract Background Data on real-world antiarrhythmic and anticoagulant therapy use in elderly atrial fibrillation (AF) patients are lacking; thus, we performed a subanalysis of data from the ANAFIE registry to clarify the current management of Japanese patients aged ≥75 years with non-valvular AF. Methods The ANAFIE registry was a multicenter, prospective, observational study. Patients were stratified into three groups: rhythm control group, rate control group, and no antiarrhythmic group. The CHADS2, CHA2DS2-VASc, and HAS-BLED scores were used to estimate embolic and bleeding risk. Results Among 32,490 patients, the overall frequencies of AF by type were 42.0 % (paroxysmal), 30.1 % (persistent and long-standing persistent), and 27.9 % (permanent). Significant differences (p Conclusions Use versus non-use and antiarrhythmic therapy varied significantly by age, stroke risk scores, type of AF, and DOAC use between subgroups.
