Eligibility
Key inclusion 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:

* Over 22 years of age

* Left ventricular ejection fraction (LVEF) less than or equal to 45% by means of echocardiography, radionucleotide angiography, left ventriculography or cardiac MRI documented less than 12 weeks before randomisation
* Diagnosis of sleep disordered breathing (SDB) with an apnoea-hypopnoea-index (AHI) of >15/hr with at least 50% central events and a central AHI of at least 10/hr
* Clinically stable with no change in medication and no unplanned hospitalisation for heart failure in preceding month
* Optimised medical treatment according to the applicable guidelines
* Able to provide informed consent

ADDITIONAL INCLUSION CRITERIA FOR THE SUBSTUDY
