This review summarizes the association between obstructive sleep apnea and atrial fibrillation, highlighting pathophysiologic mechanisms and the impact of CPAP on reducing AF prevalence and recurrence.
Does continuous positive airway pressure (CPAP) treatment reduce atrial fibrillation prevalence and recurrence in patients with obstructive sleep apnea?
This review summarizes the evidence linking obstructive sleep apnea with atrial fibrillation and highlights the potential benefit of CPAP therapy in reducing AF recurrence.
Atrial fibrillation (AF) and obstructive sleep apnea (OSA) are very prevalent diseases in modern society. Recent years have seen the emergence of a wide body of literature suggesting an important association between these two diseases. This review will provide a summary of this evidence as it currently exists. First, it will review the literature suggesting an association between AF and OSA by highlighting the prevalence of AF in OSA, the correlation of AF prevalence with OSA severity and the trend towards increased AF recurrence in patients with OSA after treatment for AF. Second, it will identify the possible pathophysiologic mechanisms for this association. In doing so, it will discuss the investigated effects of intrathoracic pressure changes, autonomic instability and atrial remodeling. Finally, it will review the evidence of the effect of treatment of OSA on AF, highlighting the role of continuous positive airway pressure (CPAP) in the treatment of OSA and its impact on AF prevalence and recurrence.
Digby et al. (Wed,) conducted a review in Atrial fibrillation and obstructive sleep apnea. Continuous positive airway pressure (CPAP) was evaluated on Atrial fibrillation prevalence and recurrence. This review summarizes the association between obstructive sleep apnea and atrial fibrillation, highlighting pathophysiologic mechanisms and the impact of CPAP on reducing AF prevalence and recurrence.
