[Correlation between coagulation and fibrinolysis in patient with cerebrovascular accident at acute stage]
Insights
This study on cerebrovascular accidents found hypercoagulable states in cerebral infarction and subarachnoid hemorrhage, with increased fibrinolysis in cerebral hemorrhage and subarachnoid hemorrhage. Antithrombin III levels were decreased in cerebral infarction.
Area of Science:
- Neurology
- Hematology
- Vascular Biology
Context:
- Cerebrovascular accidents (CVAs) encompass a range of conditions affecting blood flow to the brain.
- Understanding the coagulation and fibrinolysis status during the acute phase of CVAs is crucial for diagnosis and treatment.
- Previous research has explored hemostatic changes in specific stroke types, but a comprehensive comparison is needed.
Purpose:
- To investigate and compare the coagulation and fibrinolysis profiles in patients experiencing acute stages of different types of cerebrovascular accidents.
- To identify specific hemostatic abnormalities associated with cerebral infarction, cerebral hemorrhage, and subarachnoid hemorrhage.
Summary:
- Acute cerebral infarction is characterized by a hypercoagulable state linked to decreased antithrombin III levels.
- Cerebral hemorrhage shows normal antithrombin III levels but slightly decreased alpha 2-plasmin inhibitor, suggesting increased fibrinolytic activity as a secondary response.
- Subarachnoid hemorrhage presents with a hypercoagulable state and elevated fibrinolytic activities, potentially indicating a predisposition to disseminated intravascular coagulation.
Impact:
- These findings highlight distinct hemostatic derangements in different CVA subtypes.
- Understanding these differences can inform targeted therapeutic strategies for managing coagulation and fibrinolysis in stroke patients.
- The study suggests subarachnoid hemorrhage may serve as a precursor to disseminated intravascular coagulation, warranting further investigation.
Abstract:
Ninety five patients with cerebrovascular accidents were studied on their coagulation and fibrinolysis at acute stage of their onset. From the data collected in the present study, following findings were obtained; 1) Hypercoagulable state, which are responsible for the decreased antithrombin III levels, was observed at acute stage of cerebral infarction. 2) Findings from patients with cerebral hemorrhage were normal antithrombin III levels and slightly decreased alpha 2-plasmin inhibitor. These imply the fact of increased fibrinolytic activities. It is suggested that increased fibrinolysis are secondary reaction of cerebral hemorrhage. 3) Findings from patients with subarachnoid hemorrhage showed hypercoagulable state and increased fibrinolytic activities. It is considered that subarachnoid hemorrhage might have mostly a preparatory condition of disseminated intravascular coagulation among cerebrovascular accidents.
