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:
≥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
