Abstract:
Objective To analyze the outcomes of catheter ablation for persistent atrial fibrillation(AF)and the independent risk factors for its recurrence in the elderly.Methods A total of 194 patients with persistent AF who underwent catheter ablation at our department from January 2019 to December 2021 were enrolled in this study.They were divided into elderly group(≥60 years old,99 cases)and non-elderly group(＜60 years old,95 cases).Their surgical characteris-tics,postoperative complications and recurrence were compared between the two groups,and the independent risk factors for postoperative recurrence were analyzed in the elderly group.Results Advanced age,higher B-type natriuretic peptide,larger proportions of hypertension and coronary heart disease,and increased CHA2DS2-VASc and HAS-BLED scores,while lower male ratio and estimated glomerular filtration rate were observed in the elderly group than the non-elderly group(P＜0.05,P＜0.01).The elderly group had a higher proportion of left atrial fibrosis than the non-elderly group(30.3％vs 8.4％,P=0.001).Postoperative complications in the elderly group in-cluded 1 case of pericardial effusion and 2 cases of hematoma at the puncture site,and all of these were improved after treatment.There were no significant differences in the 1-year success rate(71.7％vs 69.5％,P=0.763)or recurrence rate during blanking period(21.2％vs 21.1％,P=0.981)between the elderly and non-elderly groups.AF duration(HR=1.020,95％CI:1.007-1.032,P=0.002)and recurrence during blanking period(HR=6.781,95％CI:3.078-14.935,P=0.001)were independent risk factors for postoperative recurrence in the elderly group.Conclu-sion Catheter ablation is safe and effective in the treatment of persistent AF in the elderly.The elderly patients with long duration of AF and recurrences during blanking period are more likely to experience recurrences within 1 year after ablation.
