About this tool

Five-element score (History, ECG, Age, Risk factors, Troponin) that stratifies undifferentiated emergency department chest pain into low, moderate and high risk of 6-week MACE.

Intended use

Adults presenting to the emergency department with symptoms suggestive of acute coronary syndrome.

Outcome

Major adverse cardiac events (death, MI, coronary revascularisation)

Time horizon

6 weeks

Derivation population

Adult ED patients with chest pain in Dutch hospitals (derivation 2008; multicentre validation 2013).

Do not use in

STEMI, obvious non-cardiac chest pain, haemodynamic instability.

Limitations

  • History and ECG items are subjective, with moderate inter-rater agreement.
  • Developed with conventional troponin; high-sensitivity assays require validated accelerated pathways.
  • Not a substitute for serial troponin testing.

Clinical problems

Evidence

Evidence level

Strong evidence

Derived and externally validated in multiple cohorts (including prospective studies) and incorporated into major clinical guidelines. Methodology

Guideline status

Listed among clinical decision pathways in the 2021 AHA/ACC multi-society chest pain guideline.

Discrimination

Reported C-statistic 0.83 in the 2013 multicentre validation (vs 0.75 TIMI and 0.70 GRACE in the same cohort).

Geographic applicability

Validated in Europe, North America and Asia.

Validation studies

Prospective multicentre validation (Backus 2013)
2,440 patientsProspectiveExternal

Unselected ED chest-pain patients, 10 Dutch hospitals

6-week MACE: low 1.7%, moderate 16.6%, high 50.1%; C-statistic 0.83.
