Screening for Sleep-Disordered Breathing in Patients Hospitalized for Heart Failure.

چکیده
S leep-disordered breathing (SDB) represents a highly prevalent comorbidity in heart failure (HF) patients. Approximately 45% of stable patients with either heart failure with reduced ejection fraction (HFrEF) or preserved ejection fraction have moderate to severe obstructive sleep apnea (OSA) or central sleep apnea (CSA) (1,2), and this prevalence is even greater in patients with acutely decompensated heart failure (ADHF) (3). Although OSA was identified as an independent risk factor for the development of HF (4), CSA with Cheyne-Stokes respiration is usually attributed to the pathophysiology of severe systolic dysfunction. Several observational studies suggest that effective treatment of SDB in HF may translate into improved quality of life, cardiac function, and even survival (5–10). These studies suggest that cardiologists need to be prepared to screen, diagnose, and even treat SDB in HF patients.
