Abstract

Diabetes mellitus and atrial fibrillation (AF) are two global epidemics that frequently coexist, with diabetes mellitus contributing to both an increased risk of new-onset AF and a worse prognosis. Pathophysiological mechanisms underlying this relationship include chronic inflammation, oxidative stress, atrial remodeling, autonomic dysfunction, advanced glycation end-products and epicardial adiposity. Management remains challenging; however, recent advances offer promise, including guideline-directed anticoagulation, tailored rate and rhythm control, and particularly, novel antidiabetic therapies, such as sodium-glucose cotransporter 2 inhibitors and glucagon-like peptide-1 receptor agonists, may improve AF outcomes. A comprehensive, individualized approach is essential to mitigate morbidity and mortality in this high-risk population.

Keywords: Diabetes mellitus; Atrial fibrillation; Arrhythmia; Atrial remodeling; Pathophysiology; Management

Core Tip: Diabetes and atrial fibrillation are closely related conditions that increase cardiovascular risk through shared mechanisms of metabolic dysfunction, inflammation and atrial remodeling. Their coexistence complicates treatment decisions, yet novel strategies are reshaping care. Beyond optimized anticoagulation and rhythm control, emerging antidiabetic agents show promise in improving outcomes. This comprehensive review highlights current evidence, evolving therapies and the need for individualized management to reduce the burden of morbidity and mortality in this population.
