HEART Score Calculator
Risk-stratify chest pain with the HEART score (History, ECG, Age, Risk factors, Troponin) to estimate the six-week risk of a major cardiac event. Example: moderately suspicious history, normal ECG, age 55, two risk factors and normal troponin score 3, a low-risk result.

Formula and method
HEART score = History (0 to 2) + ECG (0 to 2) + Age (0 to 2) + Risk factors (0 to 2) + Troponin (0 to 2). Range 0 to 10.
HEART score risk groups
| Score | Risk | 6-week MACE risk | Approach |
|---|---|---|---|
| 0 to 3 | Low | 1 to 2% | Consider early discharge |
| 4 to 6 | Moderate | 12 to 17% | Observe, test further |
| 7 to 10 | High | 50 to 65% | Early invasive strategy |
Components
| Component | 0 points | 1 point | 2 points |
|---|---|---|---|
| History | Slightly suspicious | Moderately | Highly |
| ECG | Normal | Non-specific changes | ST deviation |
| Age | Under 45 | 45 to 64 | 65+ |
| Risk factors | None | 1 to 2 | 3+ or known disease |
| Troponin | Normal | 1 to 3x | Over 3x |
Where it comes from
The score was derived and validated in emergency department patients with chest pain in the Netherlands and has since been validated in many countries.
