Clinical
- Shortness of breath (dyspnea) - classic symptom.
- Tachycardia.
- Chest pain.
- Findings associated with deep vein thrombosis
- Leg pain.

Notes:
- Venous thrombosis OR~=12 for PE.[1]
Risks factors (VTE)
- Trauma.
- Immobility.
- Pregnancy.
- Medications (e.g. OCPs).
- Hypercoagulable states (memory device CALMSHAPES):[2]
- Protein C deficiency.
- Antiphospholipid antibody syndrome (APLA).
- Leiden factor V deficiency.
- Malignancy.
- Protein S deficiency.
- Homocystinemia.
- Antithrombin deficiency.
