Emergency Department Detection of Chest Pain Score (EDACS)
Identifies chest pain patients at low-risk for major adverse cardiac events
The Emergency Department (ED) Detection of Chest Pain Score (EDACS) is a derived and validated accelerated diagnostic protocol designed to identify patients with chest pain who are low-risk for major adverse cardiac events (MACE). In conjunction with an EKG showing no new ischemia and two negative troponins (at 0- and 2-hours), this tool is >99% sensitive for MACE and allows for safe discharge from the ED with outpatient follow-up as appropriate.
The score was derived1 in 2014, and compared to another CDR for chest pain in a prospective RCT2 of 558 patients. The negative predictive value (NPV) in this comparison and subsequent validation study3 was 100%. EDACS is a highly sensitive tool that can reduce patient length of stay and improve identification of low-risk patients presenting with chest pain to the emergency department.

Sex M/F (male +6; female 0)
Age 18-50 AND known coronary artery disease (CAD) or ≥3 risk factors (Yes +4; No 0)
CAD defined by: previous ACS, previous CABG, or previous PCI
Risk factors defined by: hypertension, dyslipidemia, diabetes, current smoker, family history of early CAD
Diaphoresis (Yes +3, No 0)
Pain radiates to arm, shoulder, neck, or jaw (Yes +5, No 0)
Pain occurred or worsened with inspiration (Yes -4, No 0)
Pain reproduced by palpation (Yes -6, No 0)
The total EDACS score is determined by the sum of variables listed above.
