Assessing the probability of Major Adverse Cardiac Events (MACE) within 6 weeks.

Identifying low-risk patients suitable for early discharge without bedside observation or immediate provocative testing.

New ST-segment elevation (STEMI): These patients require immediate reperfusion.

Hemodynamic instability or obvious alternative life-threatening diagnosis (e.g., tension pneumothorax).

Patients with new, clearly ischemic ECG changes (ST-depression ≥1mm).
