Brief Summary

In patients with underlying heart diseases like hypertensive heart disease, coronary heart disease or dilative cardiomyopathy obstructive sleep-apnea, central sleep-apnea and Cheyne-Stokes-respiration are common finding in polysomnography. In a lot of these patients it is neither a purely obstructive sleep-apnea syndrome nor a complete Cheyne-Stokes-respiration but a combination of both sleep related respiratory disturbances. Previous studies showed an improvement of the central respiratory disorder, for example Cheyne-Stokes-respiration, under continuous positive pressure breathing (CPAP) and an improvement of the left ventricular pump function. (Naughton 1995, Tkacova 1997). However, the recently published CanPAP study could not prove any improvement in the mortality among CPAP therapy patients in comparison to the optimal medical treatment, although under this therapy, the number of breathing disturbances, the oxygen saturation at night and the ejection fraction of the left ventricle showed a significant improvement.(Bradley 2005) Earlier studies proved the adaptive servo ventilation to be an effective therapy for patients with central sleep-apnea and Cheyne-Stokes-respiration respectively. (Teschler 2001) Teschler's study showed that the adaptive servo ventilation therapy with a reduction of central sleep apnea down to 10/hours succeeded. With the SOMNOvent CR a new therapy-algorithm has been developed for the adaptive servo ventilation in patients with obstructive sleep apnea and Cheyne-Stokes-respiration with underlying heart disease. In the first validation study this therapy was very effective and presented only few adverse effects in the patients. (Galetke 2007) The goal of the study was to compare this new therapeutic option (SOMNOvent CR) with the established method of continuous positive airway pressure (CPAP) in patients with combination of obstructive sleep-apnea syndrome and Cheyne-Stokes-respiration with underlying heart disease.
