Treatment of Central Sleep Apnea in Heart Failure Patients
Central sleep apnea (CSA) is a neurological breathing disorder, resulting from intermittent disruptions in the neural drive to breath. CSA differs substantially from the more prevalent Obstructive Sleep Apnea (OSA), which occurs as a result of muscles relaxing in the upper airway and preventing the passage of airflow. Sleep apnea is classified as "central" when over 50% of the apnea-hypopnea index (AHI) is driven by central events.CSA is a common and serious comorbidity in patients with heart failure (HF), with a prevalence of 30-50% in patients with a reduced left ventricular ejection fraction LVEF 45%.
