Although epidemiological studies have established the role of obesity in independently predicting the occurrence and progression of AF, the pathophysiological mechanisms associated with AF in obese patients are complex and remain unclear. Obese patients are susceptible to AF, which may be related to systemic changes caused by obesity, such as hemodynamic changes, hypertension, diabetes, and the OSA syndrome. Additionally, in terms of molecular biology, adipose tissue secretes a variety of pro-inflammatory and pro-fibrotic factors that can accelerate the structural and functional remodeling of the left atrium and induce and maintain electrical conduction abnormalities. Oxidative stress induced by adipose tissue and activated autonomic nerves in the ganglion plexus are also involved in the occurrence of AF.
