When to use
Identify intermediate-risk PE patients who may deteriorate.
How it works
SBP 90–100 (2), troponin elevation (2), RV dysfunction (2), HR ≥ 110 (1). Stage I 0–2, II 3–4, III ≥ 5.
Key points
- Applies only to haemodynamically stable PE.
- Higher stages warrant closer monitoring.
- Combine with sPESI and biomarkers.

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.
| Systolic BP 90–100 mmHg | No (> 100) |
|---|---|
| Elevated cardiac troponin | No |
| RV dysfunction (echo/CT) | No |
| Heart rate ≥ 110/min | No |
→BOVA0/7
- Stage：Stage I — low (~4% complications)
- Use：Applies only to haemodynamically stable PE; identifies those at higher risk of deterioration.
| Systolic BP 90–100 mmHg | Yes (+2) |
|---|---|
| Elevated cardiac troponin | Yes (+2) |
| RV dysfunction (echo/CT) | Yes (+2) |
| Heart rate ≥ 110/min | Yes (+1) |
→BOVA7/7
- Stage：Stage III — high (~42%)
- Use：Applies only to haemodynamically stable PE; identifies those at higher risk of deterioration.

- Inputs: Systolic BP 90–100 mmHg No (> 100), Elevated cardiac troponin No, RV dysfunction (echo/CT) No, Heart rate ≥ 110/min No → Result: BOVA 0 /7（Stage: Stage I — low (~4% complications), Use: Applies only to haemodynamically stable PE; identifies those at higher risk of deterioration.） Inputs: Systolic BP 90–100 mmHg Yes (+2), Elevated cardiac troponin Yes (+2), RV dysfunction (echo/CT) Yes (+2), Heart rate ≥ 110/min Yes (+1) → Result: BOVA 7 /7（Stage: Stage III — high (~42%), Use: Applies only to haemodynamically stable PE; identifies those at higher risk of deterioration.）
