Key Points
- Stabilize ABCs; treat life‑threatening derangements immediately.
- Confirm diagnosis early with highest‑yield imaging/labs.
- Initiate guideline‑based therapy and escalate by response.
- Plan disposition and follow‑up explicitly.
Clinical Synopsis & Reasoning
Intermediate‑high risk PE features RV strain and positive biomarkers without sustained hypotension. Anticoagulate all patients. Escalate to systemic thrombolysis for decompensation or refractory shock if bleeding risk permits; consider catheter‑directed thrombolysis/thrombectomy in experienced centers. Engage a PE response team when available.
Treatment Strategy & Disposition

Engage a PE response team when available.
Epidemiology / Risk Factors
- Risk varies by comorbidity and precipitating factors
Initial Targets
| Parameter | Target/Action |
|---|---|
| Hemodynamics | Maintain perfusion; avoid hypotension |
| Monitoring | Serial exam, labs, and imaging |
| Therapy | Start early, reassess, de‑escalate when appropriate |
Investigations
| Test | Role / Rationale | Typical Findings | Notes |
|---|---|---|---|
| CBC | Screen leukocytosis/anemia | Context‑specific | Trend response |
| BMP | Electrolytes/renal function | Derangements common | Replace K+/Mg2+ |
| Key imaging | Condition‑specific (CTA/MRI/Endoscopy) | See text | Do not delay when red flags |
Pharmacology
| Medication | Mechanism | Onset | Role in Therapy | Limitations |
|---|---|---|---|---|
| Heparin (IV) or DOAC | Anticoagulant | Immediate | All unless contraindicated | Transition per guideline |
| Alteplase (systemic) | Thrombolytic | Minutes | High risk or deterioration | ICH risk; strict selection |
Prognosis / Complications
- Outcome depends on timeliness of diagnosis and definitive therapy
Patient Education / Counseling
- Explain red flags, adherence, and follow‑up plan
