Methodology · worked example, guidelines & full notes
Intermediate-high-risk PE is anticoagulated with close monitoring, reserving rescue reperfusion for hemodynamic decompensation rather than upfront thrombolysis. (original synthesis · not guideline verbatim)
When to use
Use to assign risk and treatment: high-risk PE needs immediate reperfusion, while stable patients are anticoagulated and monitored, with rescue reperfusion reserved for decompensation.
How it works
Unstable → high-risk, systemic thrombolysis + anticoagulation. Stable: RV + troponin both positive → intermediate-high (monitor, rescue thrombolysis); one positive/high score → intermediate-low; sPESI = 0 and normal RV/troponin → low-risk. NOAC preferred.
Key points
- Intermediate-high-risk PE is anticoagulated with close monitoring, reserving rescue reperfusion for hemodynamic decompensation rather than upfront thrombolysis. (original synthesis · not guideline verbatim)
- Low-risk patients meeting criteria (e.g. Hestia) may be considered for early discharge or home treatment.
- NOACs are preferred except in severe renal impairment, antiphospholipid syndrome, or pregnancy, with at least 3 months of therapy.

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.
| Hemodynamically unstable (shock/persistent hypotension) | Yes |
|---|---|
| sPESI ≥ 1 or PESI III-V (suggests risk) | Yes |
| Right-heart dysfunction (TTE/CTPA, RV/LV ≥ 1.0) | Present |
| Elevated troponin | Present |
→Risk stratificationHigh-risk PE
- Decision：Hemodynamically unstable (shock or persistent hypotension) = high-risk
- Reperfusion：Immediate systemic thrombolysis (preferred, greatest benefit within 48 h of onset); thrombolysis contraindicated or failed → catheter-directed therapy or surgical embolectomy
- Anticoagulation/support：Simultaneously start parenteral anticoagulation (unfractionated heparin); hemodynamic support (cautious fluids, norepinephrine if needed), ECMO bridging possible
| Hemodynamically unstable (shock/persistent hypotension) | No |
|---|---|
| sPESI ≥ 1 or PESI III-V (suggests risk) | No (sPESI = 0) |
| Right-heart dysfunction (TTE/CTPA, RV/LV ≥ 1.0) | Absent |
| Elevated troponin | Absent |
→Risk stratificationLow-risk PE
- Decision：Hemodynamically stable; sPESI = 0
- Management：Anticoagulation suffices (NOAC preferred); eligible patients may be considered for early discharge/home treatment (e.g. Hestia criteria)
- Anticoagulation：NOAC preferred (except severe renal impairment, antiphospholipid syndrome, pregnancy, etc., where LMWH/warfarin is used); at least 3 months, assess extension by provoking factors and recurrence risk

FAQ
Frequently asked questions
- What are the limits and cautions when using Acute Pulmonary Embolism Risk Stratification & Treatment?
- 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 Acute Pulmonary Embolism Risk Stratification & Treatment 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 Acute Pulmonary Embolism Risk Stratification & Treatment calculated in practice? Can you show a worked example?
- Inputs: Hemodynamically unstable (shock/persistent hypotension) Yes, sPESI ≥ 1 or PESI III-V (suggests risk) Yes, Right-heart dysfunction (TTE/CTPA, RV/LV ≥ 1.0) Present, Elevated troponin Present → Result: Risk stratification High-risk PE（Decision: Hemodynamically unstable (shock or persistent hypotension) = high-risk, Reperfusion: Immediate systemic thrombolysis (preferred, greatest benefit within 48 h of onset); thrombolysis contraindicated or failed → catheter-directed therapy or surgical embolectomy, Anticoagulation/support: Simultaneously start parenteral anticoagulation (unfractionated heparin); hemodynamic support (cautious fluids, norepinephrine if needed), ECMO bridging possible） Inputs: Hemodynamically unstable (shock/persistent hypotension) No, sPESI ≥ 1 or PESI III-V (suggests risk) No (sPESI = 0), Right-heart dysfunction (TTE/CTPA, RV/LV ≥ 1.0) Absent, Elevated troponin Absent → Result: Risk stratification Low-risk PE（Decision: Hemodynamically stable; sPESI = 0, Management: Anticoagulation suffices (NOAC preferred); eligible patients may be considered for early discharge/home treatment (e.g. Hestia criteria), Anticoagulation: NOAC preferred (except severe renal impairment, antiphospholipid syndrome, pregnancy, etc., where LMWH/warfarin is used); at least 3 months, assess extension by provoking factors and recurrence risk）
