How this service works
Granger 2003 in-hospital GRACE 1.0: integer nomogram points from age, heart rate, systolic BP, creatinine (mg/dL or µmol/L), Killip class 1-4, cardiac arrest, ST-segment deviation, and elevated initial enzymes. Total 1-372. In-hospital mortality percent is that paper's printed score readout. Not GRACE 2.0, not Fox 2006 6-month, not ESC 108/140 cutoffs. Not a medical device and not a cath-lab order.
Output
Returns the total GRACE 1.0 integer nomogram score (range 1–372) and the corresponding in-hospital mortality percentage as published in the Granger 2003 paper. The score is the sum of points from all eight variables per the original printed nomogram.
Example use cases
ACS triage in the ED
“I have a 75-year-old ER patient with a heart rate of 112, systolic BP of 88, creatinine of 2.1 mg/dL, Killip class 3, cardiac arrest on arrival, ST deviation on the ECG, and elevated troponins — what is their GRACE 1.0 score and in-hospital mortality risk?”
Low-acuity ACS risk check
“Score this lower-risk ACS patient using the Granger 2003 GRACE nomogram: age 52, heart rate 72 bpm, systolic BP 148 mmHg, creatinine 0.9 mg/dL, Killip class 1, no cardiac arrest, no ST deviation, and no elevated enzymes.”
Creatinine in SI units
“Compute the GRACE 1.0 in-hospital mortality for a 60-year-old with heart rate 101 bpm, systolic BP 130 mmHg, creatinine 185 µmol/L, Killip class 2, no cardiac arrest, ST deviation present, and elevated initial enzymes.”

Endpoint
GEThttps://api.magentlab.com/api/calc/graceWhen to prefer
Use this endpoint when you need the original Granger 2003 GRACE 1.0 nomogram integer score and its associated in-hospital mortality readout — not GRACE 2.0, not Fox 2006 6-month risk, and not the ESC 108/140 cutoff classifications. Ideal for reproducing published risk stratification exactly as described in the 2003 paper.
Side effects
- Missing required parameters (age, heart_rate_bpm, sbp_mm_hg, killip_class, cardiac_arrest, st_deviation, elevated_enzymes) returns validation error
- Killip class outside 1–4 returns an error
- Age, heart rate, or BP outside stated bounds returns validation error
- Neither creatinine_mg_dl nor creatinine_umol_l provided returns error
- Payment failure (402) if x402 payment header not included or insufficient USDC balance
