Insights
This study found distinct lipid profiles in stroke types. Hemorrhagic stroke patients had lower total cholesterol and LDL-C, while ischemic stroke patients showed higher total cholesterol, LDL-C, and Lp(a) levels.
Area of Science:
- Neuroscience
- Cardiovascular Medicine
- Biochemistry
Context:
- Stroke is a leading cause of death and disability worldwide.
- Lipid and lipoprotein profiles are known risk factors for cardiovascular diseases, including stroke.
- Understanding specific lipid alterations in different stroke subtypes is crucial for targeted prevention and treatment strategies.
Purpose:
- To investigate and compare serum lipid and lipoprotein levels in patients with hemorrhagic stroke and ischemic stroke.
- To identify common and distinct lipid-associated risk factors for each stroke subtype.
- To determine the independent predictive value of specific lipid parameters for hemorrhagic versus ischemic stroke.
Summary:
- Serum lipid and lipoprotein levels were analyzed in 180 acute stroke patients (90 hemorrhagic, 90 ischemic) and 107 controls.
- Hemorrhagic stroke patients exhibited lower total cholesterol (TC), LDL-C, and Lp(a) compared to controls.
- Ischemic stroke patients showed higher serum TC, LDL-C, Lp(a), and lower HDL-C and ApoAI levels than controls.
- Common risk factors included smoking, hypertension, and family history.
- Lowered TC was an independent risk factor for hemorrhagic stroke, while elevated Lp(a) was an independent risk factor for ischemic stroke.
Impact:
- Provides novel insights into the differential roles of lipids and lipoproteins in hemorrhagic versus ischemic stroke pathogenesis.
- Highlights the potential for targeted lipid management strategies based on stroke subtype.
- Contributes to a more nuanced understanding of stroke risk factors, aiding in personalized medicine approaches.
Abstract:
The serum levels of lipids and lipoproteins were measured in 180 consecutive patients with acute stroke(90 hemorrhagic stroke, 90 ischemic stroke) and 107 age- and sex-matched controls. As compared with the control group, hemorrhagic group had lower levels of total cholesterol(TC) (P < 0.05), low density lipoprotein-cholesterol(LDL-C) (P < 0.01) and Lp(a) (P < 0.05) while the ischemic group had higher serum TC(P < 0.05), LDL-C(P < 0.01), Lp(a) (P < 0.01) and lower high density lipoprotein-cholesterol(HDL-C) (P < 0.05) and ApoAI(P < 0.01). Multiple factor logistic regression showed that cigarette smoking, hypertension and family history of stroke were the common risk factors for both hemorrhagic and ischemic stroke, and that lowered TC and elevated LP(a) levels were independent risk factors for hemorrhagic stroke and ischemic stroke respectively.
