Development of an Innovative Clinico-biological Score for the Early Detection of Acute Renal Failure Associated With Cardiac Surgery.

"The biomarkers tested will be:~* creatinine levels \[pre-, post-CC, H6\],~* Plasma NGAL \[Pre-, Post-CC, H6\].~* Urinary NGAL \[H6\]~* Plasma cystatin C \[Pre-CC, Post-CEC \& H6\],~* plasma HI \[pre-, post-CC, H6\],~* plasma IL-6 \[post-CC, H6\],~* uremia \[pre-, post-CC, H6\],~* urinary DKK3 \[pre-CC\],~* urinary CCL-14 \[H6\],~* plasma angiopoietin-2 \[H6\],~* plasma PENK-A \[H6\]~These biomarkers will, if necessary, be corrected for hemodilution or dilution of urine, if any, using \[pre-, post-CC, H6\] protein and \[pre-, post-CC, H6\] creatinine, respectively."
