Brief Summary:
This is a multicenter, prospective, randomized clinical trial (pilot study). 20 participants with diastolic heart failure will be assigned to ventilation therapy (AutoSet CS ™ ASV device; therapy group). The trial will run for 6 months, after which change in echocardiographic parameters of diastolic left ventricular function, sleep and quality of life parameters will be evaluated.

Condition or disease Intervention/treatment Phase

Arm Intervention/treatment

Non-invasive Ventilation used to control central and obstructive sleep apnea.
Other Name: AutoSet CS

Primary Outcome Measures :
  1. Change in Apnea-Hypopnea-Index (AHI) [ Time Frame: 6 months ]

Secondary Outcome Measures :
  1. Change in total sleeping time (TST) determined by parameters of polysomnography [ Time Frame: 6 months ]
    Total sleeping time (TST) will be measured in minutes (min).

  2. Change in sleep quality determined by parameters of polysomnography [ Time Frame: 6 months ]
    Sleep Quality will be defined by sleep architecture (time spent in sleep Phase 1,2,3 and REM).

  3. Change in sleep efficacy determined by parameters of polysomnography [ Time Frame: 6 months ]
    Sleep efficacy is defined as TST/total time spent in bed, i.e. sleep/awake periods.

  4. Change of echocardiographic parameter of diastolic left ventricular ejection fraction function E/è [ Time Frame: 6 months ]
    E (mitral inflow velocity) and è (mitral annular early diastolic velocity) are parameters to measure filling of the left ventricle with blood.The E/è Ratio gives an estimation of the filling pressure of the left ventricle.

  5. Change of echocardiographic parameters of diastolic function [ Time Frame: 6 months ]
  6. Change of NYHA stage [ Time Frame: 6 months ]
  7. Change of nocturia [ Time Frame: 6 months ]
  8. Changes of questionnaires: ESS [ Time Frame: 6 months ]
    ESS (Epworth Sleepiness Scale) estimates the sleepiness of a person during daytime.

  9. Changes of questionnaires: MLHFQ [ Time Frame: 6 months ]
    MLHFQ (Minnesota Living with Heart Failure) estimates how much HF impairs the daily life of a patient.

  10. Changes of questionnaires (PHQ9) [ Time Frame: 6 months ]
    PHQ9 (Patient health questionnaire) assesses depression of a patient.

  11. Changes of questionnaires (SF12HSQ) [ Time Frame: 6 months ]
    SF12HSQ (short form health status) assesses physical and mental health status.

  12. Change in NT-pro BNP and BNP [ Time Frame: 6 months ]
    NT-pro BNP and BNP (unit ng/l) are comprehensive protein markers of heart diseases, inflammations and cardiovascular disorders. Outcome: Assessment of heart disease status.

  13. Changes in blood gas analysis [ Time Frame: 6 months ]
  14. Change of galactin-3 [ Time Frame: 6 months ]
  15. Change in 6 minute walk test (MWT) [ Time Frame: 6 months ]
  16. Hospitalisations (reason) [ Time Frame: 6 months ]
    Reasons will be described in the corresponding files: Type of disease: Treatment related or unrelated?

  17. Hospitalisations (cumulative length) [ Time Frame: 6 months ]
    Length of hospitalizations are measured in days (d). Severity of disease.

  18. Change in morning blood pressure [ Time Frame: 6 months ]
  19. Change in morning heart rate [ Time Frame: 6 months ]
  20. Occurrence of Adverse Events (AE) and Serious Adverse Events (SAE) [ Time Frame: 6 months ]
  21. Changes in parameters of cardiac repolarisation (QT(c), TpTe(c) intervals, TpTe/QT ratio) in ECG at rest [ Time Frame: 6 months ]
    Electrocardiogram parameters are being put together to assess the patient's heart function status. Outcome: Number of patients with normal heart function.

  22. Changes in occurrence of ventricular and supraventricular arrhythmias (PSG-ECG) [ Time Frame: 6 months ]
    Parameters are being put together to assess the patient's heart function status. Outcome: Number of patients with arrhythmias.

  23. Analysis of compliance data [ Time Frame: 6 months ]
  24. Changes in spiroergometry data (substudy) [ Time Frame: 6 months ]
