  Purpose

The purpose of this study is to assess changes in left ventricular performance using echocardiography as well as ventricular remodelling, changes in sleep and changes in mood, anxiety and cognitive functions occurring as a result of treatment of predominant central sleep apnoea by adaptive servoventilation (ASV) in chronic heart failure in addition to optimal medical therapy in chronic heart failure. This will be a substudy of the SERVE-HF study.

Primary Outcome Measures:
  • Change in Left Ventricular Ejection Fraction (LVEF) from baseline to 12 months of therapy as measured by echocardiography (Echo). [ Time Frame: Baseline (Randomization), 6- and 12 month-Follow-up-visit ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Changes in left and right ventricular function [ Time Frame: Baseline (Randomization), 6-and 12-month-Follow-up visit ] [ Designated as safety issue: Yes ]
  • Changes in LV systolic and diastolic indexed volumes [ Time Frame: Baseline (Randomization), 6- and 12-month-Follow-up-visit ] [ Designated as safety issue: Yes ]
  • Changes in right ventricular (RV) systolic and diastolic indexed volumes [ Time Frame: Baseline (Randomization), 6- and 12-month-Follow-up-visit ] [ Designated as safety issue: Yes ]
  • Changes in LV and RV mass [ Time Frame: Baseline (Randomization), 6- and 12-month-Follow-up-visit ] [ Designated as safety issue: Yes ]
  • Changes in LV sphericity index and LV end-systolic global wall stress [ Time Frame: Baseline (Randomization), 6- and 12-month-Follow-up-visit ] [ Designated as safety issue: Yes ]
  • Changes in sleep duration and sleep stages as well as arousals [ Time Frame: Baseline (Randomization), 6- and 12-month-Follow-up-visit ] [ Designated as safety issue: Yes ]
  • Changes in sleep-disordered breathing [ Time Frame: Baseline (Randomization), 6- and 12-month-Follow-up-visit ] [ Designated as safety issue: Yes ]
  • Changes in quality of life assessed by Kansas City Cardiomyopathy Questionnaire (KCCQ) [ Time Frame: Baseline (Randomization), 6- and 12-month-Follow-up-visit ] [ Designated as safety issue: Yes ]
  • Changes in mental status assessed by Mini-Mental State Examination (MMSE) [ Time Frame: Baseline (Randomization), 6- and 12-month-Follow-up-visit ] [ Designated as safety issue: Yes ]
  • Changes in Patient Health Questionnaire-9 (PHQ-9) score and Patient Anxiety Questionnaire GAD-7 [ Time Frame: Baseline (Randomization), 6- and 12-month-Follow-up-visit ] [ Designated as safety issue: Yes ]

Detailed Description:

This substudy is performed within the SERVE-HF Study, a randomised, multi-centre,international trial with parallel group design, with patients randomised to either control (optimal medical management) or active treatment (optimal medical treatment plus use of adaptive servoventilation) in a 1:1 ratio. The randomization will be the same as in the parent study. For this purpose, the randomization of the parent study will be stratified as to whether a patient is included in the substudy or not. 300 patients will be recruited for the substudy overall.

For the purpose of this substudy, patients will be followed up for a period of 12 months.

The following extra tests will be performed at the baseline visit, the 3 months follow up and the 12 months follow up:

  • Echocardiogram (for both groups)
  • cMRI (for both groups)
  • PSG (at the baseline visit only for patients in the treatment group and at 3 months follow up and the 12 months follow up for all patients)
  • 4 questionnaires (for both groups)
  • Additional blood testing (for both groups)
  Eligibility

Ages Eligible for Study:   22 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Criteria

The inclusion and exclusion criteria are mainly those applicable for the parent study; SERVE−HF. The inclusion and exclusion criteria are listed here.

INCLUSION CRITERIA FOR SERVE-HF STUDY:
