title: Using the Mehran risk scoring tool to predict risk for contrast medium-induced nephropathy in patients undergoing percutaneous angiography.
abstract: 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 the Mehran 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
  The Mehran risk scoring tool provides reliable data before patients have percutaneous angiography.
