Two patients were excluded due to insufficient study duration. ![]() Thirty-five patients with stable chronic heart failure completed the study (mean age 70.9 ± 10.5 years and body mass index 30.0 ± 4.7 kg/m 2). ![]() Subpopulation comparison based on ejection fraction was not realized due to population size. Global sleep apnea was evaluated according to the AHI, which was analyzed and compared. All participants were tested for sleep apnea using ApneaLink and polysomnography simultaneously during an overnight stay at a sleep laboratory. MethodsĪdult patients with a prior hospitalization in an acute heart failure hospital unit were recruited for the study. A prospective cross-sectional study in patients with chronic heart failure was carried out to assess the sensitivity and specificity of apnea-hypopnea index (AHI) measurements using ApneaLink against the standard polysomnography test. ApneaLink is a portable device for the screening of sleep apnea, a prevalent and underdiagnosed comorbidity in heart failure patients.
