Insights
This review details established and emerging risk factors for ischemic stroke, including hypertension, diabetes, and genetic predispositions. Managing these factors is vital for preventing stroke, a leading cause of death and disability.
Area of Science:
- Neurology
- Cardiovascular Medicine
- Genetics
Context:
- Ischemic stroke remains a leading cause of death and disability globally.
- Understanding evolving risk factors is critical for effective prevention strategies.
- Established risk factors include hypertension, diabetes mellitus, hyperlipidemia, atrial fibrillation, smoking, and heavy alcohol consumption.
Purpose:
- To review current topics and new developments in ischemic stroke risk factors.
- To highlight both established and recently identified risk factors.
- To emphasize the importance of risk factor management for primary stroke prevention.
Summary:
- Established risk factors for ischemic stroke include hypertension, diabetes mellitus, hyperlipidemia, atrial fibrillation, cigarette smoking, and heavy alcohol drinking.
- Emerging risk factors identified in recent studies include homocysteine, cardiac embolism sources (e.g., patent foramen ovale), antiphospholipid antibodies, lipoprotein abnormalities (Lp(a), remnant-like particle), insulin resistance/hyperinsulinemia, infectious agents (Chlamydia Pneumoniae), and C-reactive protein (CRP).
- Genetic studies reveal that gene polymorphisms are significant risk factors for specific stroke subpopulations, underscoring stroke's polygenic nature.
Impact:
- Effective management of identified risk factors is crucial for primary stroke prevention.
- This knowledge aids clinicians in identifying at-risk individuals and implementing targeted interventions.
- Advances in understanding stroke etiology contribute to reducing the global burden of stroke-related mortality and disability.
Abstract:
Current topics and new developments in risk factors for ischemic stroke were reviewed. Hypertension, diabetes mellitus, hyperlipidemia, atrial fibrillation, cigarrette smoking, and heavy alcohol drinking have been established as being common treatable risk factors for stroke. Recent studies have clarified that homocysteine, various cardiac sources of embolism such as patent foramen ovale, antiphopholipid antibodies, lipoprotein (Lp) abnormalities including Lp(a) and remnant-like particle, insulin resistance or hyperinsulinemia, infectious diseases such as Chlamydia Pneumoniae, and CRP are additional risk factors for stroke. In addition, genetic studies using single nucleotide polymorphisms have suggested that many gene polymorphisms are significant risk factors for certain subpopulations of stroke, which is recognized to be a polygenic disease. Management of these risk factors is crucial for primary prevention of stroke, which is the leading cause of death or disability all over the developed countries.
