Insights
Coagulation disorders
Area of Science:
- Neurology
- Hematology
- Genetics
Background:
- The link between coagulation disorders and ischemic stroke is not fully understood.
- Screening for these conditions and managing them post-stroke remains uncertain.
Purpose of the Study:
- To review data on coagulation abnormalities and ischemic stroke.
- To discuss the utility of screening and management strategies.
Main Methods:
- Literature review of inherited and acquired coagulation disorders.
- Analysis of their association with ischemic stroke.
- Evaluation of screening and management recommendations.
Main Results:
- Evidence on the role of specific coagulation abnormalities (e.g., Factor V Leiden, antiphospholipid syndrome) in ischemic stroke was reviewed.
- The clinical utility of screening and therapeutic implications were assessed.
Conclusions:
- The role of coagulation disorders in ischemic stroke pathogenesis requires further elucidation.
- Evidence-based recommendations for screening and management are discussed.
Abstract:
The role of coagulation disorders in the pathogenesis of (recurrent) ischemic stroke is uncertain. Therefore, the clinical utility of screening patients with ischemic stroke for these conditions and the therapeutic implications of a detected coagulation disorder in a patient who experienced ischemic stroke are uncertain. We reviewed the currently available data on the relationship between various inherited and acquired coagulation abnormalities (factor V Leiden and prothrombin G20210A mutations, deficiencies of protein C, protein S and anti-thrombin, hyperhomocysteinemia, the antiphospholipid syndrome and increased levels of fibrinogen) and ischemic stroke. Based on the existing evidence we discuss the usefulness of screening stroke patients for prothrombotic conditions and current recommendations regarding the optimal management of ischemic stroke patients in whom a coagulation disorder is found.
