Résumé
Atrial fibrillation (AF) is the most prevalent sustained cardiac arrhythmia, with its incidence rising due to aging populations, obesity, and advancements in diagnostic modalities. The interplay between sleep disorders and AF is increasingly recognized, with obstructive sleep apnea (OSA) serving as a well-established risk factor. However, emerging evidence implicates additional sleep disturbances-including central sleep apnea, insomnia, and restless legs syndrome-in AF pathogenesis and progression. Despite compelling observational data, interventional studies evaluating the impact of sleep disorder treatment on AF outcomes have yielded mixed results. Although continuous positive airway pressure therapy in patients with OSA mitigates AF recurrence, randomized controlled trials have yet to confirm a definitive causal benefit. This review synthesizes epidemiological, mechanistic, and interventional data linking sleep disorders to AF.
