Serum and Urine Metabolome Studies in Patients With Acute Kidney Injury After Cardiac Surgery

Serum and Urine Metabolome Studies in Patients With Acute Kidney Injury After Cardiac Surgery

The goal of this observational study is to learn about serum and urine metabolome in patients after cardiac surgery.

The main objective of this study is to collect blood and urine samples from patients after cardiac surgery, and to perform metabolomic analysis to find the differential metabolites and their enrichment pathways in AKI patients and non-AKI patients.The secondary objective is to intervene in its enrichment pathway to find ways to improve CSA-AKI.
