Serum lipids, platelets, and fibrinolytic activity in cerebrovascular disease
Insights
Patients with occlusive cerebrovascular disease showed elevated serum triglycerides and lipoproteins, alongside increased platelet activity and reduced fibrinolytic activity. These factors may contribute to atheroma and large vessel occlusion in the brain.
Area of Science:
- Neurology
- Vascular Biology
- Biochemistry
Background:
- Occlusive cerebrovascular disease, specifically ischemic thrombotic cerebrovascular disease (ITCBVC), poses a significant health risk.
- Understanding the underlying mechanisms of ITCBVC is crucial for effective prevention and treatment.
Purpose of the Study:
- To investigate the clinical features, angiographic findings, and associated biochemical and hematological markers in patients with ITCBVC.
- To identify potential risk factors contributing to atheroma formation and large vessel occlusion in the cerebrovascular system.
Main Methods:
- Study included fifty patients diagnosed with ITCBVC.
- Evaluated clinical presentation, angiographic results, serum lipid profiles, platelet function tests, and fibrinolytic activity.
- Compared findings with age- and sex-matched control groups.
Main Results:
- Abnormal angiograms were observed in 24 out of 36 patients, with common findings including internal carotid artery abnormalities and middle/anterior cerebral artery occlusions.
- Patients exhibited statistically significant elevations in serum triglycerides, pre-beta lipoproteins, platelet adhesiveness, and aggregation.
- A significant decrease in fibrinolytic activity was noted in the patient group compared to controls.
Conclusions:
- Elevated serum lipids and enhanced platelet activity, coupled with reduced fibrinolytic capacity, are strongly associated with ITCBVC.
- These factors are implicated as potential contributors to atheroma development, leading to large vessel occlusion in cerebrovascular disease.
Abstract:
Fifty patients with occlusive cerebrovascular disease (ischemic thrombotic cerebrovascular disease--ITCBVC) were studied for clinical features, angiographic findings, serum lipids, platelet functions and fibrinolytic activity. Angiograms were abnormal in 24 of 36 cases. Two-thirds of these had an abnormality of the internal carotid artery in the neck; one-third had occlusion of the middle and/or anterior cerebral arteries. A statistically significant rise of serum triglycerides, pre-beta lipoproteins, platelet adhesiveness and aggregation, and a decrease in fibrinolytic activity were noticed in these patients as compared to age and sex matched controls. The correlation coefficient did not show any intercorrelation between the platelet adhesiveness and raised lipid fractions. These factors could be responsible for the atheroma resulting in large vessel occlusion.
