How this service works
Body 2016 T-MACS logistic ACS probability from caller-assigned ECG ischaemia, worsening angina, right-arm radiation, vomiting, observed sweating, hypotension (SBP <100), and Roche Elecsys hs-cTnT ng/L. Uses that paper's rounded coefficients. Bands p<0.02 very_low, 0.02<=p<0.05 low, 0.05<=p<0.95 moderate, p>=0.95 high. magent does not interpret ECG or assay troponin. Not original MACS, HEART, EDACS, or Vancouver. Not a diagnosis or medical device.
Output
Returns a numeric ACS probability (0 to 1) computed from Body 2016 T-MACS logistic regression coefficients, plus a categorical risk band: very_low (p<0.02), low (0.02≤p<0.05), moderate (0.05≤p<0.95), or high (p≥0.95).
Example use cases
ED chest pain ACS triage
“I have a chest pain patient in the ED: ECG ischaemia present, no worsening angina, no right-arm radiation, vomiting present, sweating observed, BP is fine (no hypotension), and their Roche Elecsys hs-cTnT came back at 45 ng/L. What does T-MACS say the ACS probability and risk band are?”
Very-low-risk rapid discharge evaluation
“Can you run the T-MACS calculation for a patient who has no ECG ischaemia, no crescendo angina, no right-arm pain, no vomiting, no observed sweating, no hypotension, and a hs-cTnT of 4 ng/L — are they in the very-low-risk band?”
High-risk ACS flag for admission decision
“Patient has ECG ischaemia, worsening angina, right-shoulder radiation, vomiting, sweating observed, hypotension on arrival, and Elecsys hs-cTnT of 850 ng/L. Plug these into T-MACS and tell me the probability and risk band so I can decide on admission.”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/t_macsWhen to prefer
Use this endpoint when you need to apply the Body 2016 T-MACS (troponin-only MACS) logistic rule specifically — it is distinct from the original MACS, HEART, EDACS, and Vancouver rules. Choose it when the caller has already assigned ECG ischaemia status and clinical signs, and when a Roche Elecsys hs-cTnT value in ng/L is available. Not appropriate as a substitute for HEART score, EDACS, or Vancouver chest pain rule calculations.
Side effects
- Missing any required query parameter (ecg_ischaemia, worsening_angina, pain_radiation_right_arm_or_shoulder, vomiting, sweating_observed, hypotension, hs_ctnt_ng_l) returns a validation error
- hs_ctnt_ng_l outside supported numeric range is clamped at 0–100000; non-numeric values cause an error
- Boolean parameters passed as strings rather than true/false JSON booleans may cause parse errors
- Service may return 402 if payment header is not provided or USDC balance is insufficient
