Does obesity affect atrial fibrillation ablation outcomes? Insights from a national atrial fibrillation catheter ablation registry: One-year follow-up.

ABSTRACT:

Background

Atrial fibrillation (AF) is the most common sustained arrhythmia in adults and is associated with significant morbidity and mortality. Obesity is a known risk factor for AF, but its impact on the success of AF ablation and the risk of recurrence remains inconclusive.

Objective

This study evaluated the safety and efficacy of AF ablation across different obesity subgroups.

Methods

This prospective, nationwide, multicenter registry study included 878 patients who underwent AF ablation between January 2019 and December 2021. Participants were categorized into nonobese and obesity classes I-III (body mass index [BMI] ≥30 kg/m²) per the World Health Organization classification. Procedural characteristics, clinical outcomes, and adverse events were coll
