How this service works
Pocock 2013 MAGGIC integer score from 13 heart-failure predictors (age, EF, NYHA, creatinine, diabetes, not prescribed beta-blocker, SBP, BMI, HF duration >18 months, current smoker, COPD, male sex, not prescribed ACEI/ARB), including the published age×EF and SBP×EF extras. Returns integer score and Table 4 1-year and 3-year death probabilities for scores 0-50. Not a diagnosis, not a treatment order, not a reason to withhold therapy. magent does not examine the patient.
Output
Returns the computed MAGGIC integer score (0–50 range) and the published Table 4 1-year and 3-year mortality probability values corresponding to that score, based on the Pocock 2013 model including age×EF and SBP×EF interaction terms.
Example use cases
Pre-discharge HF risk stratification
“Before we discharge this 72-year-old female heart failure patient, run the MAGGIC score for me: EF 22%, NYHA class II, systolic BP 105 mmHg, BMI 31, she has COPD and diabetes, she's on an ACE inhibitor and a beta-blocker, HF for more than 18 months, non-smoker — what are her 1-year and 3-year mortality risks?”
HF clinic follow-up prognostication
“At today's clinic visit for my 60-year-old male HF patient — EF 35%, NYHA class II, SBP 130 mmHg, BMI 24, current smoker, no diabetes, no COPD, on both beta-blocker and ARB, HF diagnosed less than 18 months ago — can you compute his MAGGIC score and look up the death probabilities?”
Quality improvement mortality benchmarking
“I'm auditing our heart failure cohort. For a 79-year-old male with EF 18%, NYHA class IV, SBP 95 mmHg, BMI 19, diabetes, COPD, no beta-blocker, no ACE inhibitor or ARB, HF over 18 months, non-smoker — what does the MAGGIC model say his 1-year and 3-year mortality probabilities are?”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/maggicWhen to prefer
Use this endpoint when you need to compute the validated Pocock 2013 MAGGIC integer score specifically, including the published age×EF and SBP×EF interaction extras, and retrieve the official Table 4 mortality probability lookup — particularly for cardiology clinical decision support, HF risk stratification workflows, or mortality benchmarking where adherence to the published scoring algorithm matters.
Side effects
- Missing required query parameters returns a validation error
- Out-of-range values (e.g. age <18 or >120, EF outside 1-90, BMI outside 10-80, NYHA outside 1-4) return an error
- Score outside the 0-50 Table 4 lookup range may return null probabilities
- Payment failure or missing x402 payment header results in 402 Payment Required
- Invalid enum value for sex (not 'male' or 'female') causes a 400 error
