Mehran Contrast-Induced Nephropathy Risk
Mehran contrast-induced nephropathy risk score after PCI (weighted points, bands <=5 / 6-10 / 11-15 / >=16) with CIN and dialysis percentages (Mehran 2004).
Open the calculator → Runs in your browser. Data leaves only if you deliberately send a problem report from the interactive tool.
Example
- Congestive heart failure
- Yes
- Diabetes
- Yes
- Contrast volume
- 300 mL
- eGFR
- 30 mL/min/1.73m^2
Result: Mehran score 15: high risk: ~26.1% contrast-induced nephropathy, ~1.09% dialysis (Mehran 2004).
The tool opens with these values already filled in. Replace them with your own.
What the result means
- Bands
- <= 5 low (~7.5%), 6-10 moderate (~14%), 11-15 high (~26.1%), >= 16 very high (~57.3%) CIN risk per Mehran 2004.
What you enter
- Hypotension (5)
- Intra-aortic balloon pump (5)
- Congestive heart failure (5)
- Age > 75 (4)
- Anemia (3)
- Diabetes (3)
- Contrast volume (1 per 100 mL)
- eGFR (40-60 = 2, 20-40 = 4, <20 = 6)
How this is calculated
- Points
- Hypotension 5, IABP 5, CHF 5, age > 75 = 4, anemia 3, diabetes 3, contrast 1 per 100 mL, eGFR (40-60 = 2, 20-40 = 4, < 20 = 6).
