BACKGROUND AND AIM: We investigated the utility of the preprocedural red cell distribution width (RDW) for predicting contrast-induced acute kidney injury (CI-AKI) in patients with ST-segment-elevation myocardial infarction (STEMI) who underwent a primary percutaneous coronary intervention.
MATERIALS AND METHODS: A total of 630 consecutive patients who were routinely referred to coronary angiography for STEMI were included in the present study.
RESULTS: CI-AKI was observed in 79 patients (12.5%). The RDW, neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio, and the mean platelet volume were significantly higher in the CI-AKI group than in the non-CI-AKI group (P<0.001, P=032, P=0.025, and P=0.039, respectively). Serum total bilirubin and direct bilirubin levels were not different among the study groups. Using multivariate logistic regression analysis, we found that left ventricular ejection fraction [odds ratio (OR)=0.972, 95% confidence interval (CI) 0.945-0.998, P=0.033], estimated glomerular filtration rate (OR=0.970, 95% CI 0.959-0.981, P<0.001), contrast volume (OR=1.007, 95% CI 1.002-1.012, P=0.009), and RDW (OR=1.406, 95% CI 1.120-1.792, P=0.005) were independent predictors of CI-AKI.
CONCLUSION: Red blood cell distribution width, an inexpensive and easily measurable laboratory variable, is associated independently with the development of CI-AKI. Our data suggest that RDW may be a useful marker in CI-AKI risk stratification.
