📖 What is the HEART Score?
The HEART score is a validated clinical prediction rule for patients presenting to the emergency department with chest pain. It helps estimate the risk of a major adverse cardiac event (MACE) – including myocardial infarction, coronary revascularization, or cardiac death – within 6 weeks.
The 5 components (each scored 0, 1, or 2):
- H – History (symptom suspicion)
- E – ECG findings
- A – Age
- R – Risk factors for CAD
- T – Troponin level
✨ Clinical Utility
- Score 0–2: Low risk (0.9–1.7% MACE at 6 weeks) – consider early discharge or outpatient stress testing.
- Score 3–4: Moderate risk (12–16% MACE) – consider observation or further testing.
- Score 5–7: High risk (50–65% MACE) – likely ACS; admit for invasive management.
💡 Pro tip: A HEART score of 0–2 with two negative troponins has a negative predictive value >99% for 30-day MACE.
⚠️ Important Considerations
- Validated only in patients with suspected acute coronary syndrome (ACS).
- Should be used in conjunction with serial troponin measurements.
- Risk factor definition: hypertension, hypercholesterolaemia, diabetes, smoking, obesity (BMI > 30), family history of CAD (first-degree relative < 55 male / < 65 female).
- Clinical judgment always supersedes the score, especially in patients with abnormal vital signs or dynamic ECG changes.
❓ Frequently Asked Questions
A meta‑analysis of 17 studies (over 45,000 patients) showed that a HEART score ≤2 has a pooled sensitivity of 99.3% and negative predictive value of 98.8% for 6‑week MACE. The score 5–7 has a positive likelihood ratio of 16.8 for MACE.
Yes. The HEART score is most accurate when combined with serial high‑sensitivity troponin measurements at 0 and 2–3 hours. Many protocols use HEART score + 0/1‑hour algorithm.
