Contrast-Induced Nephropathy and the Vascular Patient

Ishibashi et al in this issue of Angiology assess the usefulness of serum cystatin C for predicting contrast-induced nephropathy (CIN) in patients undergoing coronary catheterization. Baseline serum cystatin C was both a predictor of CIN in patients with moderate renal insufficiency and a predictor of cardiac events after the occurrence of CIN. In the same issue, Shaker et al support that cystatin C and serum neutrophil gelatinaseassociated lipocalin may be early predictive biomarkers for CIN following percutaneous coronary angiography; both markers increase before serum creatinine (SCr) values following angiography. This editorial considers some additional aspects of CIN.
