GRACE Score (in-hospital mortality)
Compute the simplified GRACE (Global Registry of Acute Coronary Events) score for risk stratification in non-ST-elevation acute coronary syndromes.

Example
- Age
- 70 years
- Heart rate
- 95 bpm
- Systolic BP
- 115 mmHg
- Creatinine
- 1.2 mg/dL
- Killip class
- 1
Result: GRACE 143: high risk (>3% in-hospital mortality).
The tool opens with these values already filled in. Replace them with your own.
What the result means
- <=108
- Low risk: roughly under 1% predicted in-hospital mortality.
- 109-140
- Intermediate risk: roughly 1-3% predicted in-hospital mortality.
- >140
- High risk: roughly over 3% predicted in-hospital mortality.
What you enter
- Age
- Heart rate
- Systolic BP
- Creatinine
- Killip class
- Cardiac arrest at admission
- ST-segment deviation
- Abnormal cardiac enzymes
What this is
Inputs are age, heart rate, systolic blood pressure, creatinine, Killip class (clinical heart-failure category), cardiac arrest on arrival, ST-segment deviation on the presenting ECG, and elevated cardiac biomarkers. Sophie Well sums the published point values and returns the total along with the in-hospital and six-month all-cause mortality bands from the GRACE Project derivation cohort.
When to use it
Use this on an NSTE-ACS patient in the ED or chest-pain unit to choose between an early-invasive strategy (cath within 24 hours, recommended for intermediate- and high-risk GRACE bands) and an ischemia-guided strategy. GRACE is the strongest validated risk score for this purpose and is referenced explicitly in current ACC/AHA and ESC NSTE-ACS guidelines. It is not appropriate for STEMI (where immediate reperfusion supersedes risk scoring) and should not be used to triage non-ACS chest pain - use HEART for that population.
