Score Breakdown
This tool is for educational purposes only. Clinical decisions must be made by qualified healthcare professionals following institutional protocols. HEART score alone does not establish a diagnosis.
HEART Score Reference
| Score | Risk Category | MACE at 30 days |
|---|---|---|
| 0–3 | Low Risk | ~1–2% |
| 4–6 | Moderate Risk | ~12–16% |
| 7–10 | High Risk | ~50–65% |
Summary
The HEART score is a validated clinical decision tool used in emergency and cardiology settings to risk-stratify patients presenting with chest pain. It evaluates five parameters — History, ECG findings, Age, Risk factors, and Troponin level — each scored 0–2, yielding a total of 0–10. Scores 0–3 indicate low risk (MACE incidence ~1–2%), 4–6 moderate risk (~12–16%), and 7–10 high risk (~50–65%), guiding decisions on early discharge versus further workup or admission.
How it works
- Select the descriptor that best matches the patient's chest pain History.
- Choose the ECG finding most consistent with the patient's tracing.
- Select the patient's Age bracket.
- Check all applicable known Risk factors (hypertension, diabetes, etc.).
- Select the Troponin result relative to the laboratory's normal limit.
- The total HEART score and risk category appear instantly.
Use cases
- Emergency department triage of undifferentiated chest pain.
- Identify low-risk patients suitable for early discharge.
- Flag high-risk patients who need urgent cardiology workup.
- Support shared decision-making conversations with patients.
- Resident and student education on ACS risk stratification.
- Quality-improvement audits of chest pain pathway adherence.
