Cerebrovascular disease in western Australia: an analysis of stroke type and associated risk factors
Insights
This study on cerebrovascular disease found large artery thrombosis to be the most common stroke type. Hypertension was the primary risk factor, with increased stroke incidence in older females.
Area of Science:
- Neurology
- Vascular Medicine
- Epidemiology
Background:
- Cerebrovascular disease poses a significant health burden.
- Understanding stroke subtypes and risk factors is crucial for effective management.
Purpose of the Study:
- To analyze the types and primary risk factors of stroke in a cohort of patients with cerebrovascular disease.
- To investigate the relationship between stroke, hypertension, age, sex, and systemic vascular disease.
Main Methods:
- Retrospective analysis of 356 patients diagnosed with cerebrovascular disease.
- Categorization of stroke types: large artery thrombosis, cerebral embolism, lacunes, and intracerebral hemorrhage.
- Assessment of major risk factors, including hypertension and systemic vascular disease, alongside demographic data.
Main Results:
- Large artery thrombosis was the predominant stroke type (53%), followed by cerebral embolism (22%), lacunes (14%), and intracerebral hemorrhage (11%).
- Hypertension was identified as the leading risk factor, present in two-thirds of the patients.
- A notable increase in stroke incidence among females was observed in older age groups.
- Patients with thrombo-embolic infarction exhibited the most extensive systemic vascular disease.
Conclusions:
- Large artery thrombosis and hypertension are key factors in cerebrovascular disease.
- Age and sex influence stroke risk, particularly in post-menopausal women.
- Systemic vascular health is closely linked to stroke outcomes, especially in thrombo-embolic cases.
Abstract:
The stroke types and major risk factors in 356 patients with cerebrovascular disease were examined. Large artery thrombosis accounted for 53% of strokes, cerebral embolism for 22%, lacunes for 14% and intracerebral hemorrhage for 11%. Hypertension, detected in two-thirds of patients, was the major risk factor. The sex distribution varied with age, the major change being an increase in the number of females affected in older age groups. The extent of systemic vascular disease was greatest in patients with thrombo-embolic infarction.
