Improvements in sleep quality were noteworthy and represented the primary indication for initiating CPAP treatment.204 However, in patients with atrial fibrillation (AF) (a frequent comorbidity noted with HF), the use of CPAP for obstructive sleep apnea was helpful. In a trial of 10132 patients with AF and obstructive sleep apnea, patients on CPAP treatment were less likely to progress to more permanent forms of AF than were patients without CPAP.205 Yancy et al ACC/AHA TASK FORCE MEMBERS Glenn N.
