Outcome Measures

Primary Outcomes (1)

  • Prevalence of CSA in tested HFrEF/HFmrEF patients

    Determine the prevalence of CSA in a contemporary population of HFrEF/HFmrEF patients completing a Home Sleep Apnea Test (using a WatchPAT device) during the prevalence phase of the study.

    Through study completion, an average of 1 year

Secondary Outcomes (1)

  • Difference in cognitive function scores between the HFrEF/HFmrEF CSA and no SDB groups using the CANTAB assessment.

    Through study completion, an average of 1 year

Study Arms (3)

Case group - subjects with central sleep apnea

Patients with moderate to severe CSA defined by an apnea hypopnea index (AHI) ≥ 15 events per hour and a central apnea hypopnea index (CAHI) ≥ 50% of total AHI.

Control group - subjects with no sleep disordered breathing

Patients with no SDB defined by an AHI \< 5 events per hour.

Other SDB group - subjects with other forms of sleep disordered breathing

Patients that do not meet criteria for CSA or no SDB

Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

Adult patients 50 years or older with HFrEF/HFmrEF and no history of sleep disordered breathing (SDB) and not tested for SDB within the prior year will be tested for sleep apnea using a home sleep apnea test (WatchPAT device).

You may qualify if:

  • Diagnosed with heart failure with reduced or mildly reduced left ventricular ejection fraction (LVEF \<50%) at least 3 months prior to enrollment
  • New York Heart Association (NYHA) functional class II-IV
  • Treated and optimized on heart failure guideline directed medical therapy as indicated for at least 4 weeks, including angiotensin receptor-neprilysin inhibitors (ARNI) (or angiotensin converting enzyme inhibitors (ACEI) or angiotensin receptor blocker (ARB)), aldosterone receptor antagonists, beta-blockers and/or sodium glucose co-transporter 2 (SGLT-2) antagonists
  • Age 50 years or older
  • Signed Institutional Review Board (IRB) or Ethics Committee (EC) approved informed consent
  • In the opinion of the investigator, subject is willing and able to comply with the protocol, including the cognitive function assessment

You may not qualify if:

  • Hospitalized for heart failure-related complications in the last 4 weeks
  • History of SDB and/or prior or ongoing treatment for SDB or tested for SDB within the prior year
  • AHI ≥ 15 events per hour and CAHI ≥ 50% of total AHI (Case group) or AHI \< 5 events per hour (Control group) based on the baseline HSAT
  • Per the patient and investigator, willing and able to postpone CSA treatment until completion of the study assessment visit (Visit 3)
  • Color blindness
  • Currently taking opioids
  • Has taken medications for memory/cognition within the last 3 months (including but not limited to cholinesterase inhibitors and/or glutamate regulators)
  • Cerebrovascular accident (stroke or transient ischemic attack) in the last 12 months
  • Diagnosed with neurological disease including but not limited to history of seizures, meningitis, traumatic brain injury, amyotrophic lateral sclerosis, multiple sclerosis, attention-deficit/hyperactivity disorder (ADHD) or autism.
