EDACS Score

EDACS Score: Emergency Department Assessment of Chest Pain Score. Identifies patients safe for 2-hour early discharge.

Patient Age

45 years

Sex

Age 18-50 AND (known CAD or ≥3 risk factors)

Diaphoresis

Pain radiates to arm, shoulder, neck, or jaw

Pain reproduced by palpation (-6 pts)

Guidelines & Evidence

Verified

Last Review: 2026-07-17

When to Use

Adult patients presenting to the Emergency Department with symptoms suggestive of acute coronary syndrome (ACS)

Used to identify a cohort of patients at sufficiently low risk of major adverse cardiac events (MACE) to be safely discharged at 2 hours

Do Not Use If

Patient has unequivocal ongoing ischemia, dynamic ECG changes, hemodynamic instability, or another emergent cause for chest pain (e.g., aortic dissection, pulmonary embolism).
