EXPLORATORY ANALYSIS OF URINE PO2 PERI-PROCEDURAL KINETICS AND CI-AKI PROGNOSTIC ABILITIES IN PATIENTS UNDERGOING PCI.

Novel contrast-induced acute kidney injury (CI-AKI) biomarkers are needed to detect earlier and with greater precision the pathophysiological changes in renal medulla associated with kidney damage. We prospectively assessed the kinetics of urine oxygen tension (PO2) in control healthy individuals, and its prognostic ability for CI-AKI in patients undergoing percutaneous coronary intervention (PCI). We enrolled 202 consecutive patients (78% men, mean age 66±10 years) treated with elective or urgent PCI.
