  • Background: The estimated glomerular filtration rate (eGFR) independently predicts cardiovascular (CV) death or myocardial infarction (MI), and can be estimated by creatinine and cystatin C concentrations. We evaluated two different cystatin C assays, alone or combined with creatinine, in patients with acute coronary syndromes.Methods: Plasma cystatin C, measured with assays from Gentian and Roche, and serum creatinine was analyzed in 16279 patients from the PLATelet inhibition and patient Outcomes trial. Pearson’s correlation and agreement (Bland–Altman) between methods was evaluated. Prognostic value in relation to CV death or MI during one year of follow up was evaluated by multivariable logistic regression analysis including clinical variables and biomarkers, c-statistics and relative Integrated Discrimination Improvement (IDI).Results: Median cystatin C concentrations (interquartile intervals) were 0.83 (0.68 - 1.01) mg/L (Gentian) and 0.94 (0.80 - 1.14) mg/L (Roche). Overall correlation was 0.86 (95% confidence interval 0.85-0.86). The level of agreement was ±0.39mg/L (±2 standard deviations) (n=16279).The area under curve (AUC) in the multivariable risk prediction model with cystatin C (Gentian, Roche) or Chronic Kidney Disease - Epidemiology (CKD-EPI) added was 0.6914, 0.6913 and 0.6932. Corresponding relative IDIs were 2.96%, 3.86% and 4.68%, respectively (n=13050). Addition of eGFR by the combined creatinine-cystatin C equation yielded AUC of 0.6923(Gentian) and 0.6924(Roche) with relative IDIs of 3.54% and 3.24% respectively.Conclusions: Despite differences in cystatin C concentrations, overall correlation between the Gentian and Roche assays was good while agreement was moderate.  The combined creatinine-cystatin C equation did not outperform risk prediction compared to CKD-EPI.
