Study Notes
Venous Thromboembolism (VTE) Risk Factors
- Modifiable risk factors for VTE include obesity, smoking, and physical inactivity, which can be changed to reduce risk.
- Non-modifiable risk factors encompass age, family history, and certain genetic conditions, which cannot be altered.
Causes of Pulmonary Embolism (PE)
- The primary cause of most cases of PE is deep vein thrombosis (DVT), where a blood clot forms in a deep vein and travels to the lungs.
Virchow's Triad Components
- Virchow's Triad includes three components: stasis of blood flow, hypercoagulability, and endothelial injury, which contribute to the formation of DVT and PE.
- Any factor that falls outside this triad does not explain the mechanisms behind DVT and PE formation.
Potential Causes of VTE and PE
- Factors contributing to VTE include prolonged immobility, surgery, pregnancy, and certain medications.
- Not all conditions or factors that are sometimes considered in discussions about blood clot risks will lead to VTE or PE.
Non-modifiable Risk Factors
- Non-modifiable risk factors for VTE remain consistent and impact susceptibility, such as older age or having a genetic predisposition to clotting disorders.
