The HEART Score

Acute coronary syndrome defines a spectrum of diseases (unstable angina, NSTEMI, STEMI), without clear ECG abnormalities the diagnosis and disposition can be challenging

Several scoring systems have attempted to risk stratify patients: TIMI, PURSUIT, and GRACE

The TIMI & PURSUIT scores were designed to identify higher-risk patients and long-term mortality

A pilot/observational study has utilized a novel scoring system to risk stratify low to intermediate risk patients

The HEART (History, ECG, Age, Risk factors and Troponin) score: 

  • 0-3 points ~ 2.5% risk (data supporting discharge)
  • 4-6 points ~20.3% risk (data supporting observation)
  • ≥7points ~ 72.7% risk (data supporting early invasive strategies)

This scoring system is limited given the small study size and requires further study/validation, but may be an easy, quick, and reliable predictor of outcome in chest pain patients
