Early recognition of cardiac surgeryassociated acute kidney injury: Lack of added value of TIMP2 IGFBP7 over short-term changes in creatinine (an observational pilot study)

For the detection of cardiac surgery-associated acute kidney injury (CS-AKI), the performance of urine tissue inhibitor of metalloproteinase 2 insulin-like growth factor-binding protein 7 (TIMP2 IGFBP7) has never been compared with that of very early changes in plasma creatinine (ΔpCr).
