Prediction of Contrast-Induced Nephropathy in Patients With Serum Creatinine Levels in the Upper Normal Range by Cystatin C: A Prospective Study in 374 Patients

Abstract

CIN in patients with creatinine within the upper normal range is significantly more frequent after intraarterial than after IV contrast administration. In these patients, renal impairment after contrast administration is independently predicted by cystatin C and cystatin C/creatinine-ratio, whereas BUN and creatinine were not predictive.
