Brief Summary
The primary objective of this study is to compare the Apnea- Hypopnea Index in HF patients with concomitant CSA, after 12 weeks of CRT alone to CRT in combination with one night of overdrive pacing. Secondary objectives are to evaluate the effects of a single night of overdrive pacing applied after 12 weeks of CRT vs. CRT alone on breathing events, sleeping events, and neurohormonal markers. An additional secondary objective of the study is to compare the efficacy of CRT in HF patients with concomitant CSA to HF patients without concomitant CSA.

Study Arms (2)
CRT for patients with CSA
NO INTERVENTIONPatients suffering from HF with central Sleep Apnea (CSA) programmed to DDD/45 (CRT) for 12 weeks. Intervention is CRT.
CRT + AOP for patients with CSA
ACTIVE COMPARATORPatients suffering from HF with central Sleep Apnea programmed to DDD/+15 bpm nocturnal rate (CRT + AOP) for 12 weeks. Intervention is the AOP in addition to CRT.
Interventions
The CSA group will undergo 2 sleep evaluation on two consecutive nights, during which the device will be programmed according to the randomization scheme (one night CRT, DDD/45 and the other CRT, DDD/15 bpm over mean nocturnal heart rate). The mean nocturnal heart rate over the last week is derived from the device memory.
Eligibility Criteria
You may qualify if:
- Patients with documented clinical history of symptomatic but stable congestive heart failure, NYHA III or NYHA IV, of at least six weeks duration.
- Patient has an indication for a CRT device, or patients with previous pacemaker indication, except Sick Sinus Syndrome, and currently in need for an upgrade to a CRT device
- Patient is scheduled for the implantation of a CRT device
- Patient is over 18 years of age
- Patient provides Informed Consent
You may not qualify if:
- Inability to complete overnight sleep study as specified by the protocol
- Myocardial infarction or coronary revascularization procedure within 2 calendar months prior to enrollment
- Planned or strong likelihood of cardiac surgery within 4 months following enrollment
- A spirometric confirmation of obstructive lung disease
- Evidence of obstructive sleep apnea at baseline polysomnography
- Body mass index \>30 kg/m²
- Pregnant women
