简要总结
Obstructive sleep apnea (OSA) is a major modifiable risk factor for atrial fibrillation (AF). Continuous positive airway pressure (CPAP) therapy has been shown to improve cardiovascular outcomes; however, real-world data on its effect on AF recurrence remain limited.
This prospective cohort study aims to evaluate the association between objective CPAP adherence and the risk of AF recurrence in patients with moderate-to-severe OSA and a history of paroxysmal AF.
Patients will be followed for 12 months, with AF recurrence assessed using electrocardiography and Holter monitoring.
详细描述
This is a prospective, real-world cohort study enrolling adult patients with moderate-to-severe obstructive sleep apnea (AHI ≥ 15 events/hour) and documented paroxysmal atrial fibrillation. OSA is diagnosed using home sleep apnea testing.
All participants initiate CPAP therapy, with objective adherence data collected via telemonitoring. Patients are followed for 12 months to assess AF recurrence, progression to permanent AF, and associations with CPAP usage metrics.
