Endothelial Function Study Before Cardiovascular Surgery

Terminated

• Conditions: Chronic Obstructive Pulmonary Disease (COPD); Obstructive Sleep Apnea Syndrome (OSAS)

• Registration Number: NCT01195064
• Lead Sponsor: University Hospital, Grenoble

Brief Summary

The aim of this clinical trial is to evaluate the effect of chronic obstructive pulmonary disease (COPD) and/or obstructive sleep apnea syndrome (OSAS) on the endothelial function, before cardiovascular surgery, compared to non COPD non OSAS patients undergoing also a cardiovascular surgery, by an observational physiological study.

An interim analysis will be performed when 100 patients will be included.

Detailed Description

Secondary objectives of this clinical trial :

* To evaluate the effect of COPD and/or OSAS on the systemic inflammation, insulin-resistance and oxydative stress, in comparison with non COPD non OSAS patients.

* To evaluate the effect of COPD and/or OSAS on the inflammation and oxydative stress of the adipose tissue, in comparison with non COPD non OSAS patients.

* To validate the STOP-BANG questionnaire in patients undergoing a cardiovascular surgery
