Validated for the Bruce protocol.
When to use
Estimate prognosis after a Bruce-protocol stress test.
How it works
Score = exercise time (min) − 5 × ST deviation (mm) − 4 × angina index (0/1/2). ≥ +5 low, −10 to +4 moderate, < −10 high risk.
Key points
- Validated for the Bruce protocol.
- Low-risk results carry an excellent prognosis.
- High-risk results may prompt angiography.

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.
| Exercise time (Bruce) | 9 min |
|---|---|
| Max ST deviation | 1 mm |
| Exercise angina | Non-limiting |
→Duke TMS0
- Risk group：Moderate risk (~1.25%/yr)
- Formula：time − 5 × ST(mm) − 4 × angina index
| Exercise time (Bruce) | 9 min |
|---|---|
| Max ST deviation | 1 mm |
| Exercise angina | None |
→Duke TMS4
- Risk group：Moderate risk (~1.25%/yr)
- Formula：time − 5 × ST(mm) − 4 × angina index

FAQ
Frequently asked questions
- What are the limits and cautions when using Duke Treadmill Score?
- For licensed clinicians and clinical researchers. Interpret results with history, investigations and local protocols; not a diagnosis or prescription, and not a substitute for multidisciplinary decision-making or local guidelines.
- Does Duke Treadmill Score upload patient data? Where is it calculated?
- Calculation runs locally in the browser; inputs and results are not uploaded. For licensed clinicians only; interpret with history, investigations and local protocols — not a diagnosis or prescription.
- How is Duke Treadmill Score calculated in practice? Can you show a worked example?
- Inputs: Exercise time (Bruce) 9 min, Max ST deviation 1 mm, Exercise angina Non-limiting → Result: Duke TMS 0（Risk group: Moderate risk (~1.25%/yr), Formula: time − 5 × ST(mm) − 4 × angina index） Inputs: Exercise time (Bruce) 9 min, Max ST deviation 1 mm, Exercise angina None → Result: Duke TMS 4（Risk group: Moderate risk (~1.25%/yr), Formula: time − 5 × ST(mm) − 4 × angina index）
