FABP1 and acute kidney injury: The obtained data are in hand with the previously reported significant differences between levels of urinary L-FABP estimated at 24 and 48-h after dye injection before cardiac surgery [37] and with the conclusion that estimation of urinary L-FABP levels improves early prediction of AKI in patients hospitalized at medical cardiac intensive care units [38] and after coronary angiography/PCI [39].
