Clinical Trial Summary

The aim of this clinical trial is to evaluate the effect of obstructive sleep apnea syndrome (OSAS) treatment in heart failure patients following coronary artery bypass graft (CABG) surgery or other coronary reperfusion.


Clinical Trial Description

This clinical trial is a double-blind, randomized, placebo-controlled study.

The first objective is to evaluate the influence of continuous positive airway pressure (CPAP) treatment for OSAS on the ventricular function improvement in heart failure patients, in comparison with OSA patients treated with sham CPAP. This treatment will be instaurated just after the coronary reperfusion surgery

Secondary objectives :

- Evaluation of the effect of CPAP treatment on the endothelial function

- Evaluation of the effect of CPAP treatment on systemic inflammation

- Evaluation of the effect of CPAP treatment on oxidative stress,

- Evaluation of the effect of CPAP treatment on insulin resistance,

after the coronary reperfusion surgery, in comparison with OSA patients treated with sham CPAP and non apneic control patients, with heart failure.

- Assessment of the impact of nocturnal desaturation level on the vascular reactivity and atherosclerosis of mammary vessels collected during surgery.

- Assessment of the impact of nocturnal desaturation level on the oxidative stress, inflammation and insulin sensitivity on abdominal and epicardiac adipose tissue collected during surgery. ;
