Epworth Sleepiness Scale (ESS) - Measure Description: ESS is a self-administered questionnaire. It contains 8 questions. Questions are rated on a 4-point Likert scale (0-3); 0= would never doze, 3=high Chance of dozing. Range of scores 0-24. Global score= sum of all item scores. Copyright (c)MW Johns

Apnoea-Hypopnea-Index (AHI) at Baseline - Measure Description: The AHI is an index to describe the severity of Sleep Apnea. Apnea is cessation of breathing during sleep. Hypopnea is diminished breathing during sleep. The number of Apneas and Hypopneas are added up and divided by hours of sleep (Apneas + Hypopneas per hour). An AHI ranging from 5-15 describes mild Sleep Apnea. AHI 15-30 describes moderate Sleep Apnea. AHI >30 describes severe Sleep Apnea.

Secondary outcome [21] 0 0
Central Apnoea Index/Total AHI - Measure Description: Central apneas are partial or complete cessations of airflow caused by reduced or stopped neural Stimulation of the breathing muscles. For comparison: In obstructive apneas are caused by blocked airways that shut off the air although the breathing Stimulus is working.

- Chronic heart failure (at least 12 weeks since diagnosis) according to the current
applicable guidelines (ESC, ACC/AHA)

echocardiography, radionuclide angiography, left ventriculography, or cardiac magnetic
resonance imaging) documented less than 12 weeks before randomisation

Summary
Brief summary
The purpose of this trial is to evaluate the long-term effects and cost-effectiveness of
adaptive servo-ventilation (ASV) on the mortality and morbidity of patients with stable heart
failure due to left ventricular systolic dysfunction, already receiving optimal medical
therapy, who have sleep disordered breathing (SDB) that is predominantly central sleep apnea.
Assumptions: the intervention reduces the hazard rate by 20%. The event rate in the control
group is 35% in the first year. It is assumed that the hazard rate is constant over time.
