Nocturnal CPAP (nCPAP) therapy benefits the heart in patients with cardiovascular disease and obstructive sleep apnea (OSA)



  • nCPAP decreased risk of adverse cardiovascular events in severe OSA patients vs. untreated subjects in a prospective observational all-male 10 year follow-up study.

  • nCPAP improved cardiac function, decreased blood pressure and heart rate in patients with heart failure and OSA.

  • nCPAP decreased the number of cardiovascular deaths in OSA patients compared to untreated patients  in a study over 7.5 years in 168 patients.

  • CPAP therapy reduces arrhythmias as frequency of nocturnal ventricle premature beats was lower in CPAP treated heart failure patients with OSA
