Background: Patients who have radiological imaging with contrast material are at risk for contrast medium-induced nephropathy, reduced renal function, longer hospitalizations, and renal failure requiring dialysis. Objective: To determine whether theMehran risk scoring tool can be used to predict changes in hospitalized patients who had percutaneous angiography. Methods: Data on 196 patients admitted for cardiac angiography who had Mehran risk scores higher than 6 were analyzed retrospectively. Creatinine levels, used as predictors of contrast medium-induced nephropathy, were evaluated at day 2, day 3, and day 4 through day 7. RESULTS Creatinine levels were significantly higher in patients with a Mehran risk score of 11 or higher than in patients with a risk score of 6 to 10 at all times. Conclusions: TheMehran risk scoring tool provides reliable data before patients have percutaneous angiography.
