Summary
Elevated plasma fibrinopeptide A (FPA) levels indicate hypercoagulability and predict recurrent ischemic stroke. This finding helps identify high-risk patients for anticoagulant therapy.
Area of Science:
- Biochemistry
- Neurology
- Hematology
Context:
- Stroke is a leading cause of long-term disability.
- Understanding the mechanisms of stroke recurrence is crucial for prevention.
- Hypercoagulability and platelet activation are implicated in thrombotic events.
Purpose:
- To investigate plasma levels of fibrinopeptide A (FPA) and beta-thromboglobulin (BTG) as markers of hypercoagulability and platelet activation post-stroke.
- To determine the association of these markers with stroke recurrence, particularly cerebral reinfarction.
Summary:
- Plasma FPA, a marker of hypercoagulability, was significantly elevated in stroke patients compared to controls.
- Higher FPA levels were associated with recurrent cerebral infarction within 5 years.
- BTG, a marker of platelet activation, was elevated but not linked to recurrence.
- Multivariate analysis identified FPA levels > 4 ng/ml as a significant predictor of cerebral reinfarction.
Impact:
- These findings highlight the role of hypercoagulability in ischemic stroke recurrence.
- Identifies FPA as a potential biomarker for predicting high-risk patients.
- Provides a rationale for anticoagulant therapy trials in specific stroke subgroups.
