Duration of Acute Kidney Injury Impacts Long-Term Survival After Cardiac Surgery

The duration of AKI after cardiac surgery is directly proportional to long-term mortality. This AKI dose-dependent effect on long-term mortality helps to close the gap between association and causation, whereby AKI stages and AKI duration have important implications for patient care and can aid clinicians in evaluating the risk of in-hospital and postdischarge death.
