Effect of Semirecumbent Sleep Position on Severity of Obstructive Sleep Apnea in Patients With Heart Failure

摘要

Background: Overnight rostral leg fluid displacement in heart failure (HF) patients is related to the high prevalence and severity of obstructive sleep apnea syndrome (OSAS). We hypothesized that rostral fluid shift would decrease in a semirecumbent (45-degree elevated) position, and evaluated the effect of semirecumbent sleeping on severity of sleep apnea in HF patients with OSAS.
