Summary

This study aims to discover and validate new biomarkers for predicting CSA-AKI before cardiovascular surgery. Nested case-control studies embedded in prospective cohorts. Adult patients scheduled for cardiovascular surgery were continuously included. Blood/urine/stool samples and clinical data before and after contrast agent exposure and before and after cardiovascular surgery were collected, and the occurrence, progression and outcome of CSA-AKI events were dynamically monitored. Based on the exposure to contrast agents and the occurrence of CSA-AKI, two case-controls were constructed in the prospective cohort. In the construction of two case-controls, biomarkers were identified and validated by using multi-omics analysis techniques and machine learning techniques, etc.
