(Naughton 1995, Tkacova 1997).\n\nHowever, 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)\n\nEarlier 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)\n\nThe 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.", 'detailedDescription': 'Patients who meet all the above mentioned criteria and who were diagnosed as sleep-apnoea syndrome patients in our hospital were asked to participate in the study.\n\nWe divided the patients in two groups:\n\nGroup 1: started with CPAP and continued with SOMNOvent CR Group 2: began with SOMNOvent CR and ended with CPAP\n\nFirst of all a CPAP-titration was applied to both fixed groups during the second night. During the third night they received either the CPAP- pressure (first group) or the adaptive servo ventilation (second group. The patients were discharged from the hospital continuing with the procedure of the third night.\n\nAfter four weeks a new admission for the sleep laboratory was necessary and, during the first night, a control investigation with the procedure of the last four weeks. The procedure changed during the next night, so that the patients of the first group now slept with the SOMNOventCR-device and the patients of the second group with the CPAP-device.\n\nAfter a wash-out-period of a week and a four-week treatment with the last procedure a final in-hospital polysomnography was performed in which adaptive servo ventilation was applied to the first group and fixed CPAP to the second group.\n\nAfter the study ended, the patients received the therapy procedure which was the most effective and which was better tolerated.\n\nThe following analyses were carried out in addition to the polysomnographic measurements:\n\nAdmission 1: Berlin questionnaire, European sleep questionnaire, echocardiography, 6 minute walking test, patients questionnaire.\n\nAdmission 2: ESS, Berlin questionnaire, echocardiography, 6 minute walking test, patients´ questionnaire.\n\nAfter the wash-out-period: ESS, Berlin questionnaire, patients questionnaire.\n\nAdmission 4: ESS, Berlin questionnaire, echocardiography, 6 minute walking test, patients questionnaire.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Men and women \\> 18 years.\n* Diagnosis of arterial hypertension or a coronary heart disease or a dilative cardiomyopathy\n* Combined sleep-apnea-syndrome with a total value of AHI\\>15 per hour and a rate up to 20% of central events or periodic breathing.\n\nExclusion Criteria:\n\n* Heart failure NYHA-CLASS IV.\n* Myocardial infarction or unstable angina pectoris or cardiac surgery within the last three months.\n* Apnea-hypopnea-index \\< 15 per hour.\n* Obstructive breathing disturbances up to 80%.\n* Pregnancy.\n* Absence of declaration of consent.\n* Malign diseases.\n* Serious (Severe) chronic oxygen-requiring pulmonary illness.\n* Age under 18 years.'}, 'identificationModule': {'nctId': 'NCT00811668', 'acronym': 'VCR', 'briefTitle': 'Comparison of CPAP With SOMNOventCR in Patients With Underlying Heart Disease, Combined OSA and CSR', 'organization': {'class': 'OTHER', 'fullName': 'Wissenschaftliches Institut Bethanien e.V'}, 'officialTitle': 'Crossover Comparison of Treatment With Continuous Positive Airway Pressure and Treatment With Adaptive Servo Ventilation (SOMNOventCR) in Patients With Underlying Heart Disease, Combined Obstructive Sleep Apnea and Cheyne-Stokes Respiration.', 'orgStudyIdInfo': {'id': 'WI_VentCR_13/2008'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': 'CPAP before SOMNOVentCR', 'description': 'started with CPAP and continued with SOMNOvent CR', 'interventionNames': ['Device: CPAP before SOMNOVentCR']}, {'type': 'EXPERIMENTAL', 'label': 'SOMNOVentCR before CPAP', 'description': 'began with SOMNOvent CR and ended with CPAP', 'interventionNames': ['Device: SOMNOventCR before CPAP']}], 'interventions': [{'name': 'CPAP before SOMNOVentCR', 'type': 'DEVICE', 'description': '4 weeks CPAP treatment, 1 week wash out period, 4 weeks SOMNOventCR treatment', 'armGroupLabels': ['CPAP before SOMNOVentCR']}, {'name': 'SOMNOventCR before CPAP', 'type': 'DEVICE', 'description': '4 weeks SOMNOventCR treatment, 1 week wash out period, 4 weeks CPAP treatment', 'armGroupLabels': ['SOMNOVentCR before CPAP']}]}, 'contactsLocationsModule': {'overallOfficials': [{'name': 'Wolfgang Galetke, PD Dr.', 'role': 'STUDY_CHAIR'}, {'name': 'Winfried J.
