No Intervention: Standard HF therapy
Subjects will receive optimal standard therapy for heart failure conforming to national guidelines as determined by the referring cardiologist
Active Comparator: Standard therapy for HF + ASV
Subjects will receive treatment with Adaptive Servo Ventilation in addition to optimal standard therapy for heart failure conforming to national guidelines, as determined by the referring cardiologist
Device: Adaptive Servo Ventilation

- The time to the composite outcome of death or first CV hospital admission or new onset atrial fibrillation/flutter requiring anti-coagulation but not hospitalization or delivery of an appropriate shock from an ICD not resulting in hospitalization. [ Time Frame: The expected study follow-up period is five years ]The study will end once 540 primary endpoints have occurred. The maximum follow-up period for all randomized subjects is 5 years.
- Time to death from any cause [ Time Frame: The expected study follow-up period is 5 years ]The study will end once 540 primary endpoints have occurred.
- Number of cardiovascular hospitalizations per year of follow-up [ Time Frame: The minimum time of follow-up is expected to be 2 years. The maximum time of follow-up is expected to be 5 years ]
- Number of days alive not hospitalized [ Time Frame: Time from randomization to censoring (death, primary event or end of study) ]The number of days the patient is hospitalized are subtracted from the total number of days in the study from randomization. This number will be compared between the 2 groups.
- Changes in left ventricular function [ Time Frame: 6 months from randomization ]Changes in LV function will be assessed by echocardiography at baseline and at 6 months post randomization
- Changes in plasma BNP levels [ Time Frame: 6 months from randomization ]Changes in plasma NT-proBNP levels will be assessed at baseline and at 6 months post randomization
- Cardiac resynchronization therapy or defibrillator implantations [ Time Frame: Average number of days until first cardiac resynchronization or first defibrillator implantation ]The average number of days from randomization to the first occurrence of CRT or defibrillator implantation will be calculated and compared between each treatment arm.
- Changes in 6 minute walk test distance [ Time Frame: 6 months from randomization ]Changes in the 6-minute walk distance between baseline and 6 months will be compared between the 2 groups
- Percentage of patients with changes in stages of heart failure and functional class [ Time Frame: Values obtained at study termination will be compared to those obtained at randomization ]New York Heart Association classification and AHA/ACC Stages of Heart Failure will be assessed at each visit.
- Changes in apnea/hypopnea index [ Time Frame: 1 month from randomization ]
- Changes in Quality of life assessments [ Time Frame: Assessments made at baseline, 1, 6, 12 and every 6 months thereafter ]Minnesota living with Heart Failure Questionnaire and Epworth Sleepiness Scale will be used. Scores will be compared between the 2 groups.
