Catheter ablation of atrial fibrillation in patients with autoimmune disease: A propensity score matching study based on the China Atrial Fibrillation Registry.

ABSTRACT:

Background

Evidence on outcomes of catheter ablation (CA) for atrial fibrillation (AF) in patients with autoimmune disease (AD) is limited.

Hypothesis

Patients with AD had worse outcomes after CA procedures for AF.

Methods

A retrospective analysis was performed in patients undergoing AF ablation between 2012 and 2021. The risk of recurrence after ablation was investigated in patients with AD and a 1:4 propensity score matched non-AD group.

Results

We identified 107 patients with AD (64 ± 10 years, female 48.6%) who were matched with 428 non-AD patients (65 ± 10 years, female 43.9%). Patients with AD exhibited more severe AF-related symptoms. During the index procedure, a higher proportion of AD patients received nonpulmonary vein trigger ablation (18.7% vs. 8.4
