Introduction: The relationship between sleep disordered breathing (SDB), systolic function/heart failure in elderly people living in community has not been investigated, nor has insomnia and excessive daytime sleepiness (EDS).
Aim: To describe the prevalence of SDB and its relationship to systolic function, the different insomnia symptoms as well as EDS.
Method: 331 subjects (71-87 years) underwent echocardiographic examinations and sleep respiratory recordings. Questionnaires were used to evaluate insomnia symptoms and EDS.
Results: Mild SDB (AHI 5-15), was found in 32%. Moderate SDB (AHI 15-30) occurred in 16%, and 7% had severe SDB (AHI >30). Median AHI was significantly higher (p<0.001) in those with mild impaired systolic function (AHI 11.7) and moderate impaired systolic function (AHI 10.9) compared to those with normal systolic function (AHI 5.0). Mild and moderate impaired systolic function was also independently associated to SDB as indicated by an AHI≥10. Concerning insomnia symptoms and EDS, only difficulties in initiating sleep correlated significantly (p<0.05) with AHI.
Conclusion: SDB is common among the elderly and may be related to impaired systolic function/heart failure. However, detection of SDB in such population may be problematic since insomnia symptoms and EDS correlated poorly with SDB.
