Acute Pulmonary Embolism Classification and Management Pathway

Integrates clinical presentation, prognostic scores, imaging, biomarkers, hemodynamics, and respiratory status to support category-specific management decisions.

Guided assessment

Enter the available clinical findings

Categories are assigned using the highest-severity applicable feature. Reassess if the patient's condition changes.

01Clinical presentation

Symptoms may include: dyspnea, pleuritic chest pain, hemoptysis, syncope/presyncope, or exercise intolerance.

02Patient information

These findings contribute to the PESI, sPESI, and Bova risk summaries shown with the classification results. Elevated clinical severity is present when PESI is >85, sPESI is ≥1, or Bova is >4.

03RV assessment and biomarkers

Right-heart strain

CTRV/LV ratio ≥1.0 or septal flattening or bowing.
EchocardiogramRV/LV ratio ≥1.0, TAPSE <16 mm, or RV systolic dysfunction.

Cardiac and perfusion biomarkers

TroponinPositive when above the assay-specific upper reference limit.
NT-proBNP or BNPPositive when NT-proBNP >500 pg/mL or BNP >90 pg/mL.
Lactic acid (lactate)Positive when >2 mmol/L. A positive value is treated as a shock-level hypoperfusion marker in this classification.
Renal hypoperfusionPositive when acute kidney injury or oliguria is clinically consistent with systemic hypoperfusion. (AKI: serum creatinine rise ≥0.3 mg/dL within 48 hours or ≥1.5× baseline within 7 days; oliguria: urine output <0.5 mL/kg/hour for ≥6 hours.)
04Cardiopulmonary status

Select the single finding that best reflects the patient's current cardiopulmonary status.
