Impact of Early Renal Recovery on Survival After Cardiac Surgery-Associated Acute Kidney Injury

Early recovery of renal function is associated with improved long-term survival after CSA-AKI. This variable is clinically useful because it occurs immediately after the peak creatinine level and simultaneously helps define the severity of AKI and the magnitude of recovery. Given the high risk of death associated with postoperative AKI, early renal recovery seems to offer a distinct survival benefit and may represent an important therapeutic focus.
