Popis: Abstract Background The relationships between frailty and clinical outcomes in elderly Japanese patients with non‐valvular atrial fibrillation (NVAF) after catheter ablation (CA) have not been established. We evaluated the frailty rate of patients undergoing CA for NVAF, examined whether CA for NVAF improves frailty, and analyzed the CA outcomes of patients with and without frailty. Methods Elderly Japanese patients (≥65 years; mean age: 72.8 years) who participated in the real‐world ablation therapy with anti‐coagulants in management of atrial fibrillation registry and who responded to the frailty screening index survey were included (n = 213). Frailty and AF recurrence were assessed preoperatively and at 3 and 6 months after CA. Results Twenty‐six patients (12.8%) were frail, 109 (53.7%) were pre‐frail, and 68 (33.5%) were robust. Cardiovascular (frailty: 0.5%/person‐year; pre‐frailty: 0.1%/person‐year; robust: 0.1%/person‐year) and cardiac (frailty: 0.5%/person‐year; pre‐frailty: 0.1%/person‐year; robust: 0.1%/person‐year) events, as well as major bleeding (frailty: 0.3%/person‐year; pre‐frailty: 0.1%/person‐year; robust: 0.1%/person‐year), were numerically more frequent in the frailty group. No deaths from cardiovascular or stroke/systemic thromboembolic events occurred. A large proportion of patients did not experience 3‐month (frailty: 96.2%; pre‐frailty: 96.3%; robust: 88.2%) or 6‐month (frailty: 88.5%; pre‐frailty: 91.7%; robust: 86.8%) AF recurrence after CA. Weight loss, walking speed, and fatigue improved in the frailty and pre‐frailty groups after CA. Conclusion Japanese patients aged ≥65 years with frailty or pre‐frailty had improved frailty screening index components, such as weight loss, walking speed and fatigue, after CA. Therefore, elderly patients with frailty or pre‐frailty may benefit from CA for NVAF.
