Cardiovascular Diseases, Endothelial Dysfunction, Surgery
Conditions
Brief summary
Cardiac surgery has been described as altering endothelium structure and function, notably because of the use of cardiac-pulmonary bypass (CPB). Among the endothelial structure, glycocalyx, the thin layer recovering the endothelial surface, may be altered by the inflammatory process and probably the modification of flow during CPB. Endothelial and glycocalyx integrity are essential for vascular function and glycocalyx destruction is associated with organ failure and mortality. On the other hand, a chronic alteration of glycocalyx is observed in many diseases such as diabetes, hypertension or chronic kidney failure, all pathologies frequently observed in patients benefiting grom cardiac surgery. Thus the preoperative alteration of glycocalyx may be associated with postoperative organ failure.
