Last updated: 2026-10-30

> The GRACE score calculator estimates in-hospital mortality after an acute coronary syndrome from age, heart rate, blood pressure, creatinine, Killip class, cardiac arrest, ST deviation and cardiac enzymes.

## Inputs

- Age (years)
- Heart rate (bpm)
- Systolic blood pressure (mmHg)
- Creatinine (mg/dL, µmol/L)
- Killip class
- Cardiac arrest at admission
- ST-segment deviation
- Elevated cardiac enzymes

## Results

- GRACE score
- In-hospital mortality (NSTE-ACS)

## Formula

```
GRACE points: age 0–100; heart rate 0–46; systolic BP 0–58; creatinine 1–28; Killip class 0–59; cardiac arrest at admission 39; ST deviation 28; elevated enzymes 14
NSTE-ACS in-hospital mortality: ≤ 108 low (< 1%), 109–140 intermediate (1–3%), > 140 high (> 3%)
```

## Explanation

The Global Registry of Acute Coronary Events followed more than 11,000 patients in 14 countries. The GRACE score is recommended by European guidelines to decide how quickly patients with NSTE-ACS should have angiography.

### How to use the GRACE Score Calculator

- **Age**
- **Heart rate**
- **Systolic blood pressure**
- **Creatinine**
- **Killip class**
- **Cardiac arrest at admission**
- **ST-segment deviation**
- **Elevated cardiac enzymes**

Results update as you type, and every field accepts the units shown in its menu.

### How it works

Enter the values at presentation. Creatinine can be entered in mg/dL or µmol/L.

## Worked example

Inputs — Age: 65 years; Heart rate: 85 bpm; Systolic blood pressure: 130 mmHg; Creatinine: 1.1 mg/dL; Killip class: I – no heart failure; Cardiac arrest at admission: No; ST-segment deviation: Yes; Elevated cardiac enzymes: Yes.

Results — **GRACE score = 150 / 372**; In-hospital mortality (NSTE-ACS) = High (over 3%).

## Key terms

- **ACS**: Acute coronary syndrome.
- **Killip class**: Bedside grading of heart failure after a heart attack.

## FAQ

**What is a high GRACE score?**
Above 140 for in-hospital mortality in NSTE-ACS.

**How is the GRACE score used?**
European guidelines recommend angiography within 24 hours for scores above 140.

**Is there a 6-month version?**
Yes – GRACE also predicts 6-month mortality with slightly different points.
