Association between weight loss and outcomes in patients undergoing atrial fibrillation ablation: a systematic review and dose-response meta-analysis.

ABSTRACT:

Background

Obesity is an strong risk factor for atrial fibrillation (AF), and obesity can affect the prognosis of AF. However, the role of weight loss on outcomes after ablation remains unclear.

Objectives

This study aims to determine the relationship between weight loss and outcomes in patients with AF ablation, as well as the potential dose-response relationship.

Methods

The Cochrane Library, PubMed, and Embase databases were searched to identify studies that reported a relationship between weight loss and ablation up to August 17, 2021. Relative risks (RRs) were pooled using random-effects models.

Results

One randomized, open-labeled clinical trial and seven cohort studies involving 1283 patients were included. The mean body mass index of all included studie
