Overview
Four factors have been associated with an increased risk of contrast-induced nephropathy: pre-existing renal insufficiency, pre-existing diabetes, age, Volume of CM, and reduced intravascular volume.[1][2] A clinical prediction rule is available to estimate probability of nephropathy (increase ≥25% and/or ≥0.5 mg/dl in serum creatinine at 48 h)[3]:
Risk Factors:
Pre-existing renal disease
- Systolic blood pressure <80 mm Hg - 5 points
- Intraarterial balloon pump - 5 points
- Congestive heart failure (Class III-IV or history of pulmonary edema) - 5 points
- Age >75 y - 4 points
- Hematocrit level <39% for men and <35% for women - 3 points
- Diabetes - 3 points
- Contrast media volume - 1 point for each 100 mL
- Renal insufficiency:
- Serum creatinine level >1.5 g/dL - 4 points OR
- Estimated Glomerular filtration rate (online calculator)
- 2 for 40–60 mL/min/1.73 m2
- 4 for 20–40 mL/min/1.73 m2
- 6 for < 20 mL/min/1.73 m2
Scoring:
5 or less points
- Risk of CIN - 7.5
- Risk of Dialysis - 0.04%
6–10 points
- Risk of CIN - 14.0
- Risk of Dialysis - 0.12%
11–16 points
- Risk of CIN - 26.1*
- Risk of Dialysis - 1.09%
>16 points
- Risk of CIN - 57.3
- Risk of Dialysis - 12.8%
