❤️ EDACS (Emergency Chest Pain)
Risk-stratify emergency chest pain with EDACS and the EDACS-ADP.
EDACS-ADP enables 2-hour accelerated discharge pathways.

When to use
Identify low-risk chest pain for accelerated discharge.
How it works
Age points + male (6) + age 18–50 with CAD/≥3 risk factors (4) + diaphoresis (3) + radiation to arm/shoulder/neck/jaw (5) − pleuritic (4) − reproducible by palpation (6). Low risk = score < 16 with negative ECG and troponin at 0/2 h.
Key points
- EDACS-ADP enables 2-hour accelerated discharge pathways.
- Requires a non-ischaemic ECG and negative serial troponin.
- Score alone is not sufficient without the ADP criteria.

Worked calculation
The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.
| Age | 55 years |
|---|---|
| Sex | Female (0) |
| Age 18–50 with known CAD or ≥ 3 risk factors | No |
| Diaphoresis | No |
| Pain radiates to arm/shoulder/neck/jaw | No |
| Pain occurs/worsens with inspiration | No |
| Pain reproduced by palpation | No |
| ECG no new ischaemia AND troponin negative (0 & 2 h) | Yes |

- Age points：6
- Interpretation：Low risk (EDACS-ADP) — suitable for early discharge
| Age | 55 years |

| Pain occurs/worsens with inspiration | Yes (−4) |
| Pain reproduced by palpation | Yes (−6) |
