Clinical Evidence and Methodology

CLINICAL INSIGHT

When to Use

When to Use

  • Adult patients ≥ 18 years presenting with chest pain to Emergency or Internal Medicine
  • Stratify risk of 30-day MACE (death, MI, or revascularisation)
  • Guide decision between early discharge vs admission and invasive workup
  • Combine with serial troponins (at 0h and 2–3h) for optimal accuracy

HEART Score + Troponin Algorithm

HEART score alone is not sufficient. Always combine with two serial high-sensitivity troponin measurements. A HEART 0–3 + two negative hs-troponins = 30-day MACE risk < 2% → safe early discharge.

CLINICAL INSIGHT

How it Works

Five Components (0–2 points each)

  • H — History: Ischaemic character of chest pain
  • E — ECG: ST deviation, LBBB, LVH, or repolarisation changes
  • A — Age: < 45 = 0, 45–64 = 1, ≥ 65 = 2
  • R — Risk factors: Known atherosclerosis scores 2; ≥ 3 risk factors = 2; 1–2 risk factors = 1
  • T — Troponin: ≤ normal = 0; 1–3× ULN = 1; > 3× ULN = 2

Risk Strata

  • Score 0–3 (Low): 1.7% MACE. Early discharge safe with negative troponins.
  • Score 4–6 (Moderate): 12% MACE. Observation, serial troponins, stress testing.
  • Score 7–10 (High): 65% MACE. Early invasive strategy — catheterisation lab consultation.
CLINICAL INSIGHT

Practical Pearls

Comparison to TIMI and GRACE

  • HEART is simpler than GRACE (no haemodynamics calculation required)
  • HEART is better calibrated for ED chest pain than TIMI (which was derived in ACS patients)
  • HEART score has been validated in > 50,000 patients across 20+ countries

Known ECG/Troponin Limitation

LBBB pattern (paced or Sgarbossa-negative) can score a false +2 on ECG domain. In LBBB patients, apply Sgarbossa or modified Sgarbossa criteria to assess for STEMI equivalence separately.

CLINICAL INSIGHT

Next Steps

Disposition Algorithm

  • HEART 0–3 + 2 negative hs-troponins: Discharge home. Outpatient cardiology/stress test within 72h.
  • HEART 4–6: Observation unit or admit. Stress test or coronary CTA. Cardiology consult.
  • HEART 7–10: Full ACS management. Antiplatelet therapy. Anticoagulation. Urgent cath lab referral.

Background

HEART Score Development

Developed in the Netherlands by AJ Six and colleagues in 2008 as a simple bedside tool combining five clinical domains, each scored 0–2. Its elegant acronym (History, ECG, Age, Risk factors, Troponin) allows recall without a calculator. It has since become the dominant chest pain pathway tool in emergency medicine globally.

HEART Score

HEART Score: Chest pain risk stratification in Emergency/Internal Medicine. Score ≤ 3 = low risk pathway (safe early discharge). Predicts 30-day MACE.
