Supplementary Material for:Effect of Cardiac Surgery-Associated Acute Kidney Injury on Long-Term Outcomes of Chinese Patients: A Historical Cohort Study

Background/Aims: To evaluate the long-term outcomes of Chinese patients with cardiac surgery-associated acute kidney injury (CSA-AKI). Methods: Patients who underwent cardiac surgery with a median 3-year follow-up were enrolled. The long-term survival rate and the incidence of chronic kidney disease (CKD) were recorded, and related risk factors were analyzed. Results: Of all 1,363 patients, 457 (33.5%) developed CSA-AKI. The AKI patients had a lower 3-year survival rate (88.8 vs. 97.2%, respectively, p p Conclusion: CSA-AKI increased the risk of 3-year mortality and incident CKD stages 3-5.
