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.

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
