AKI(Acute Kidney Injury) is a common complication after cardiac surgery which is associated with increased mortality and morbidity. Collecting perioperative biosignal data and studying their association with renal outcomes can help improve kidney injury, mortality, and morbidity in cardiac surgical patients. Furthermore, the occurrence of AKI, length of hospital stay, and recovery of renal function after discharge are closely associated with the development of chronic kidney disease (CKD). Therefore, regular monitoring of renal function and related indicators in cardiac surgical patients can help improve long-term outcomes.
