Exploring risk Indicators of atrial fibrillation in severe Obesity: Left atrial cardiomyopathy and premature atrial contractions.

ABSTRACT:

Background

Although obesity is a major risk factor for atrial fibrillation (AF), its mechanisms and the diagnostic yield of AF screening in severe obesity is unclear. This study aims to enhance our comprehension of AF susceptibility in severe obesity by investigating associations between left atrial (LA) cardiomyopathy and premature atrial contractions (PACs) and to explore the diagnostic yield of AF screening.

Methods

This cross-sectional study included a total of 192 subjects aged 35-65 years with a BMI ≥ 35 kg/m², alongside 50 non-obese controls, both without known cardiac disease. Prolonged heart rhythm registration was done with either 24-hours (n = 147) or 7-day Holter monitoring (n = 75) or an implantable loop recorder (ILR) (n = 10). Furthermore, we perfor
