Insights
High blood pressure and smoking are key modifiable stroke risk factors. While genetics play a role, understanding these factors is crucial for stroke prevention and cerebral infarction management.
Area of Science:
- Neurology
- Epidemiology
- Genetics
Context:
- Stroke is a diverse neurological disorder, with cerebral infarction being the most prevalent type.
- This review focuses on identifying and understanding the risk factors associated with stroke, particularly cerebral infarction.
- The analysis is based on a comprehensive review of prospective, population-based studies identified through Medline.
Purpose:
- To review the established and potential risk factors for cerebral stroke, with a specific emphasis on cerebral infarction.
- To synthesize current knowledge on genetic associations, modifiable risk factors, and demographic influences on stroke incidence.
- To provide an overview of factors influencing stroke risk across different populations and demographics.
Summary:
- High blood pressure and cigarette smoking are identified as the most significant modifiable risk factors for stroke.
- Serum cholesterol is positively linked to cerebral infarction but not intracerebral hemorrhage.
- Diabetes, atrial fibrillation, carotid stenosis, and social class are important predictors, especially in the elderly and lower socioeconomic groups.
Impact:
- Highlights the critical role of modifiable factors like hypertension and smoking in stroke prevention strategies.
- Underscores the need for further research into genetic predispositions and their replicability across diverse populations.
- Informs public health initiatives and clinical practice by detailing key risk factors for cerebral infarction and stroke overall.
Background:
Stroke is a heterogenic group of disorders. Cerebral infarction is the largest group (80-85%) and is followed by primary intracerebral hemorrhage and subarachnoid hemorrhage. This article gives a review of risk factors for cerebral stroke, with an emphasis on cerebral infarction.
Material And Methods:
The article is based on literature identified through Medline, with emphasis on prospective, population-based studies.
Results And Interpretation:
Genetic studies of the Icelandic population have shown associations between single genes and common types of stroke, but it remains to be seen whether the results can be replicated in other populations. High blood pressure and cigarette smoking are the most important modifiable risk factors for stroke. Serum cholesterol is positively associated with cerebral infarction, but not with intracerebral hemorrhage. Diabetes, atrial fibrillation and carotid stenosis are important predictors of cerebral infarcts, especially in the elderly. Cohort studies and randomized trials have shown that hormone replacement therapy in women increases the risk of stroke, while modern oral contraceptives do not represent a risk factor for stroke in young women. There is a clear social gradient in stroke occurrence, with a higher incidence in lower social classes.
