High Coronary Heart Disease Risk in Hemodialysis Patients with Central Sleep Apnea: A Pilot Study

Background: The high prevalence of sleep apnea is reported in hemodialysis patients despite the low prevalence of obesity. The present study compared the occurrence of central sleep apnea (CSA) in hemodialysis patients with that in non-hemodialysis patients, and its association with new-onset coronary heart disease (CHD) events.Methods: Seventy-three hemodialysis and 444 non-hemodialysis patients were examined for CSA and obstructive sleep apnea (OSA) occurrence using polysomnography. Hemodialysis patients were monitored for the occurrence of new-onset CHD events.Results: Hemodialysis patients had a significantly higher central apnea-hypopnea index (AHI; 0.7, range 0.2-3.1) than age-, sex- and obstructive AHI-matched non-hemodialysis patients (0.1, range 0-1.0; p
