Summary
Coagulation disturbances, including low antithrombin III activity and increased platelet function, frequently cause thromboembolic disease. Many patients in remission show hypercoagulability, particularly after arterial events.
Area of Science:
- Hematology
- Vascular Biology
- Thrombosis Research
Context:
- Thromboembolic disease is a significant clinical challenge.
- Coagulation disorders are implicated in disease pathogenesis.
- Understanding hypercoagulability is crucial for risk stratification.
Purpose:
- To investigate coagulation system alterations in patients post-thromboembolic events.
- To quantify the prevalence of hypercoagulability in remission.
Summary:
- Assayed coagulation activities in 512 patients in remission after thromboembolic events.
- Identified diminished antithrombin III activity, reduced fibrinolytic potential, and increased platelet function.
- Detected hypercoagulable states in 40% of venous thrombosis patients and 61-89% of arterial event patients.
Impact:
- Highlights the high incidence of persistent hypercoagulability.
- Suggests potential targets for anticoagulant therapy.
- Informs risk assessment and management strategies for thromboembolic disease.
