How this service works
Gillmore 2018 NAC ATTR cardiac staging from NT-proBNP (ng/L) and caller-assigned eGFR. Stage I: NT-proBNP <=3000 and eGFR >=45. Stage III: NT-proBNP >3000 and eGFR <45. Stage II: exactly one of those two adverse cut points. Returns gillmore_stage 1/2/3. ATTRwt and ATTRv. Not Mayo AL amyloid staging. Not NYHA. Not a treatment order. magent does not compute MDRD or CKD-EPI.
Output
Returns a gillmore_stage value of 1, 2, or 3. Stage I: NT-proBNP ≤3000 ng/L AND eGFR ≥45. Stage III: NT-proBNP >3000 ng/L AND eGFR <45. Stage II: exactly one of those two adverse thresholds met. No treatment recommendations or additional computed values are included.
Example use cases
Staging newly diagnosed ATTRwt patient
“I have a new wild-type ATTR amyloidosis patient with NT-proBNP of 2800 ng/L and eGFR of 52 mL/min/1.73m² — give me their Gillmore 2018 cardiac stage.”
Monitoring ATTRv patient disease progression
“My hereditary ATTR patient's latest labs show NT-proBNP of 5100 ng/L and eGFR of 41 mL/min/1.73m² — what Gillmore 2018 stage are they in now?”
Pre-treatment cardiac risk stratification
“Before starting tafamidis, I need the Gillmore 2018 ATTR cardiac stage for a patient with NT-proBNP 1500 ng/L and eGFR 60 mL/min/1.73m².”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/gillmoreWhen to prefer
Use this endpoint when you need to apply the Gillmore 2018 NAC ATTR-specific cardiac staging system (Stage I/II/III) for ATTRwt or ATTRv patients based on NT-proBNP and eGFR. Do not use for AL amyloidosis (Mayo staging), NYHA classification, or when eGFR has not yet been calculated — this endpoint requires a pre-computed eGFR value and does not run MDRD or CKD-EPI itself.
Side effects
- NT-proBNP outside range 10–100000 ng/L returns a validation error
- eGFR outside range 5–200 mL/min/1.73m² returns a validation error
- Missing required query parameters returns an error response
- This endpoint does not compute eGFR — caller must supply a pre-calculated eGFR value
- Passing AL amyloid patients will not yield a clinically valid result as this is ATTR-specific staging
