GW27-e0025 Combining Serum Cystatin C with Creatinine, a New Definition of Contrast-induced Acute Kidney Injury and Its Clinical Implications

Contrast-induced acute kidney injury (CI-AKI), a powerful predictor of unfavorable long-term prognosis, was traditionally defined as an increase of serum creatinine (sCr) after contrast media (CM) exposure. Recently, serum cystatin C (sCyC) had been proposed as an alternative to sCr to detect acute
