[Cholesterol fractions in subjects with cerebral, coronary and peripheral vasculopathy]
Insights
This study found lower levels of HDL-cholesterol fractions in patients with atherosclerotic diseases, indicating a potential link between reduced HDL-cholesterol and cardiovascular risk.
Area of Science:
- Lipid metabolism and cardiovascular disease epidemiology.
- Biochemical analysis of lipoprotein fractions.
Context:
- Atherosclerosis is a major cause of morbidity and mortality.
- Lipid profiles, particularly HDL-cholesterol, are crucial in assessing cardiovascular risk.
- Understanding HDL-cholesterol subfractions may offer deeper insights into atherosclerotic disease mechanisms.
Purpose:
- To investigate lipaemic parameters, focusing on HDL-cholesterol fractions, in patients with different manifestations of atherosclerotic disease.
- To compare lipid profiles between patient groups (cerebral, ischemic cardiac, peripheral vasculopathy) and healthy controls.
Summary:
- Epidemiological study of 94 patients with atherosclerotic disease and 100 controls.
- Measured triglycerides, total cholesterol, LDL-C, HDL-C, HDL-3-C, HDL-2-C, and relevant ratios.
- Patients with cerebral vasculopathy showed increased TG and decreased HDL-C fractions. Ischemic cardiopathy patients had increased TG and significantly reduced HDL-C fractions.
Impact:
- Findings suggest that reduced HDL-cholesterol fractions are associated with atherosclerotic disease.
- Highlights the importance of analyzing HDL-cholesterol subfractions for a comprehensive cardiovascular risk assessment.
- May inform future research on targeted lipid-lowering therapies for atherosclerosis.
Abstract:
An epidemiological investigation of certain lipaemic parameters in some expressions of atherosclerotic disease with particular reference to HDL-cholesterol fractions is reported. The series consists of 94 normal weight subjects (45 m, 49 f, average age 61 +/- 5) subdivided as follows: 38 suffering from cerebral vasculopathy (group A), 41 from ischaemic cardiopathy (group B), 15 from peripheral vasculopathy (group C). One hundred controls aged between 41 and 70 and free from hepato-renal, endocrinometabolic and vascular diseases were also considered. In the case of each sample, plasma levels of triglycerides (TG), total cholesterol (TC), LDL-cholesterol (LDL-C), HDL-cholesterol (HDL-C), HDL-3 cholesterol (HDL-3-C), HDL-2-cholesterol HDL-2-C), HDL-C/TC and HDL-2-C/HDL-C ratios were determined with the enzymatic method. In group A, an increase in TG (P less than 0.05) was observed with respect to the controls, while values of TC and LDL-C were slightly lower: values of HDL-C, HDL-3-C and HDL-2-C were decidedly down (P less than 0.01); the HDL-C/TC and HDL-3-C/HDL-C ratios were decidedly reduced (respectively P less than 0.05 and P less than 0.01). In subjects suffering from ischaemic cardiopathy (group B), TG values (P less than 0.05) were somewhat higher than the controls and TC and LDL-C did not differ significantly. The cholesterol fractions HDL-C, HDL-3-C (P less than 0.05) and HDL-2-C (P less than 0.05) and the ratio HDL-C/TC (P less than 0.05) were sharply reduced; the HDL-2/HDL-C ratio was normal.(ABSTRACT TRUNCATED AT 250 WORDS)
