High prevalence of sleep apnea in heart failure outpatients: even in patients with preserved systolic function.

Abstract:

BACKGROUND:Sleep-disordered breathing (SDB) is common in patients with reduced ejection fraction (EF). However, little is known about the prevalence of SDB in a general heart failure population including patients with preserved EF (HFPEF). METHODS:We prospectively enrolled stable heart failure outpatients from our heart failure clinic to assess the prevalence of SDB independent of systolic left ventricular function. RESULTS:Among 115 patients (62% with reduced EF, 38% with preserved EF, New York Heart Association Class II-IV) SDB was present in 81% (27% central sleep apnea, 54% obstructive sleep apnea [OSA]). HFPEF patients had SDB in 80% of the cases, 62% had OSA. This group had significantly more hypertension. CONCLUSIONS:This study shows a high prevalence of SDB in a general heart failure population, also in patients with HFPEF. These patients have predominantly OSA. Especially in patients with HFPEF SDB should be kept in mind and referral to a sleep specialist should be considered.
