Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Cardiac surgery patients have many risk factors for endothelial dysfunction (hypertension, atherosclerosis, dyslipidemia, chronic renal failure ...).

It is likely that a significant number of patients suffering from a preexisting endothelial dysfunction. This endothelial dysfunction can be assessed by a molecular approach (determination of NO, ICAM1, VCAM1, IL8, endothelial microparticles ...). Extracorporeal circulation with ischemia-reperfusion causes a breach of particularly important glycocalyx as ischemia-reperfusion injury is. No studies have evaluated the time course of the infringement, and its association with the immediate post-operative complications (SIRS, coagulopathy, vasoplegic syndrome, renal failure). Only one study has regained an association between endothelial dysfunction during cardiac bypass surgery and postoperative cardiac surgery vasoplegic syndrome. A study in noncardiac surgery has regained an association between endothelial dysfunction (assessed by a vasoplegia test) and postoperative acute renal failure. Thus there is some data in the literature to suggest that the occurrence of postoperative complications (SIRS, coagulopathy, capillary leak syndrome, acute circulatory failure vasoplegic and acute renal failure) may result from the interaction between a pre-existing endothelial dysfunction and "operative" aggression (extracorporeal circulation). The onset of complications result from an interaction that depends on the importance of endothelial dysfunction at baseline.
