Background Previous studies have shown that frailty increases the risk of new‐onset atrial fibrillation (AF). However, little is known about the association between frailty and the recurrence of AF after radiofrequency ablation. The objective of this study was to investigate the association between frailty and the recurrence in patients with AF who had undergone radiofrequency ablation. Methods and Results A total of 450 patients >50 years of age with symptomatic drug‐refractory AF who had undergone catheter ablation for the first time were retrospectively enrolled. Frailty status was evaluated by the 11‐factor modified frailty index and 5‐factor modified frailty index. Recurrence was defined as any documented atrial tachyarrhythmia lasting >30 seconds after a 3‐month blanking period without any antiarrhythmic drugs during postablation follow‐up. Patients in the frail group were older, and had a higher CHA2DS2‐VASc score, HAS‐BLED score, left atrial diameter, and a higher proportion of comorbidities than those in the nonfrail group. Circumferential pulmonary vein isolation was successfully done in all of the patients. During a median follow‐up of 12 months, recurrence was recorded in 98 (21.8%) patients (paroxysmal AF, 20.6%; persistent AF, 23.2%). The Kaplan‐Meier analysis showed that the survival rate of freedom from atrial tachyarrhythmias in the frail group was lower than that in nonfrail groups (log‐rank P |
