Brief Summary
Sleep disordered breathing, in which patients my breath deeply, shallowly or stop breathing for periods whilst asleep, is common in heart failure and associated with a poor prognosis. This study aims to validate a novel function available on certain pacemakers which is designed to detect this condition.The investigators hypothesize that ApneaScan can accurately detect moderate to severe sleep disordered breathing in patients with heart failure as compared against an Embletta sleep study. The investigators will also follow up our patients for 2 years to determine whether the severity of sleep disordered breathing as assessed by ApneaScan correlates with prognosis.

Secondary Outcomes (1)
Adverse heart failure events
2 years
Other Outcomes (3)
B-Type Natriuretic peptide (BNP) concentration
2 years
Ejection fraction on echocardiography
2 years
6 minute walk test distance
2 years
Study Arms (1)
Pacemaker/ICD with ApneaScan
Patients with HFREF due to receive a pacemaker or ICD with ApneaScan function
Interventions
Implantation of an ICD or CRT device with ApneaScan function
Eligibility Criteria
Patients with heart failure with reduced ejection fraction (EF \<40%) due to receive a Boston Scientific ICD/CRTD/P with ApneaScan function.
You may qualify if:
- Heart failure with reduced ejection fraction (EF \< 40%)
- Due to receive a device with ApneaScan function
- Able to give informed consent
- Ambulatory
You may not qualify if:
- Known sleep disordered breathing on Non-Invasive Ventilation therapy.
