Exploring the Intricate Interplay Between Obesity and Atrial Fibrillation: Mechanisms, Management, and Clinical Implications.

Atrial fibrillation (AF) stands as a prevalent and escalating cardiac arrhythmia in the United States, with obesity emerging as a prominent modifiable risk factor. This article explores the intricate relationship between obesity and AF, delving into the multifaceted pathophysiological mechanisms linking the 2 conditions. Various factors, such as autonomic dysfunction, left atrial stretch, inflammation, and hormonal imbalances, contribute to the initiation and perpetuation of AF in obese individuals. The Atrial Fibrillation Better Care pathway, emphasizing lifestyle modifications and weight loss strategies, emerges as a practical guideline for managing AF in obesity. This comprehensive review underscores the critical role of obesity as a significant modifiable risk factor for AF, urging a proactive approach to its management. Implementing the Atrial Fibrillation Better Care approach, focusing on encouraging physical activity, promoting healthy dietary habits, and raising awareness about the risks associated with obesity prove essential in preventing and mitigating the burden of AF in the obese population.
