Heart Failure and Central Sleep Apnea

The Facts

The remedē® System is designed to improve cardiovascular health by restoring natural breathing during sleep in patients with Central Sleep Apnea.

  • Central Sleep Apnea (CSA) is a type of sleep disordered breathing, a condition that disturbs the normal breathing pattern during sleep and has an adverse effect on overall cardiovascular health.
  • Heart failure patients have a 1 in 3 chance of having CSA.
  • Symptoms of CSA are often silent such as fatigue, poor energy, and nocturia and resemble those of the underlying heart failure.
  • CSA worsens heart failure progression, increases risk of hospitalization, cardiac arrhythmias, and death.
  • Even in patients without heart failure at diagnosis, CSA increases morbidity and mortality.
  • Cheyne-Stokes Respiration is a form of CSA, often identified at night, but can occur when awake.

1 in 3 people with heart failure have Central Sleep Apnea and stop breathing during the night. Talk to your doctor about the remedē® System clinical study to see if you qualify.
