NCT02204865

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.

Outcome Measures

Primary Outcomes (1)

  • The Apnoeic-Hypopnoeic Index (AHI)

    We will compare that AHI from the ApneaScan pacemaker algorithm against the AHI from an Embletta sleep study.

    18 months

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

Device: Pacemaker/ICD

Interventions

Implantation of an ICD or CRT device with ApneaScan function
