How this service works
Mehran 2004 contrast-induced nephropathy risk score after PCI (eGFR model B). Points from hypotension, IABP, CHF, age >75, anemia, diabetes, contrast volume (1 per 100 mL), and caller eGFR. Returns integer score (max 41), risk group (low ≤5 through very_high ≥16), and development-set CIN percent. Not a CKD diagnosis; magent does not measure contrast or compute eGFR.
Output
Returns an integer total risk score (0–41), a risk group label (low ≤5, moderate 6–10, high 11–15, very_high ≥16), and the corresponding CIN incidence percentage from the Mehran 2004 development dataset.
Example use cases
Pre-procedure CIN risk stratification
“My patient is 78 years old, has a history of CHF and diabetes, is anemic, and their eGFR is 42. We plan to use about 300 mL of contrast for their PCI. They're not hypotensive and don't need an IABP. What is their Mehran CIN risk score and which risk category do they fall into?”
Post-cath AKI risk documentation
“After catheterization, I need to document the Mehran contrast nephropathy risk for a 65-year-old patient: no hypotension, no IABP, no CHF, not anemic, not diabetic, 150 mL contrast used, eGFR of 72. What score did they get and what does it mean for CIN risk?”
High-risk patient CIN counseling
“I'm counseling a 76-year-old who had IABP support during PCI, with hypotension, CHF, anemia, and diabetes — eGFR is 18 and we used 400 mL of contrast. Run the Mehran 2004 model B score and tell me the risk group and expected CIN rate.”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/mehranWhen to prefer
Use this endpoint when you need to compute the Mehran 2004 CIN risk score using the eGFR-based model B (not creatinine-based model A) for patients undergoing PCI, and the caller has already computed eGFR independently. Prefer this over manual calculation when integrating risk scoring into clinical decision support pipelines or automated cardiology workflows. Do not use if you need to compute eGFR from creatinine (that step must be done by the caller), diagnose CKD, or assess nephropathy risk outside the PCI context.
Side effects
- Missing required parameters (age, hypotension, iabp, chf, anemia, diabetes, contrast_ml, egfr_ml_min) returns a validation error
- Age outside 18–120 range is rejected
- contrast_ml outside 10–1000 range is rejected
- egfr_ml_min outside 5–150 range is rejected
- Passing serum creatinine instead of eGFR will yield incorrect scoring (model B requires eGFR, not creatinine)
- Boolean fields passed as strings may fail schema validation
- Payment failure (x402) returns 402 status if USDC payment is not provided
