[Characteristics of dyslipoproteinemia in patients with peripheral atherosclerosis]
Insights
Lower high-density lipoprotein (HDL) cholesterol levels correlate with severe leg atherosclerosis. Patients often show normal lipid levels but sometimes have dyslipoproteinemia, indicating cholesterol turnover imbalances.
Area of Science:
- Biochemistry
- Cardiovascular Medicine
- Lipid Metabolism
Context:
- Obliterating atherosclerosis of the legs is a serious condition affecting peripheral arteries.
- Lipoprotein metabolism plays a crucial role in cardiovascular health.
- Understanding lipid profiles in atherosclerosis is key for diagnosis and treatment.
Purpose:
- To investigate the relationship between high-density lipoprotein (HDL) cholesterol levels and the severity of leg atherosclerosis.
- To identify specific lipid abnormalities, such as dyslipoproteinemia, in patients with this condition.
- To explore potential imbalances in cholesterol turnover between red blood cell membranes and lipoproteins.
Summary:
- A reverse correlation was found between high-density lipoprotein (HDL) cholesterol content and the severity of clinical manifestations in patients with obliterating atherosclerosis of the legs.
- While most patients had normal concentrations of cholesterol, triglycerides, and HDL cholesterol, some exhibited dyslipoproteinemia, including hypo-alpha-lipoproteinemia.
- An increased molar ratio of cholesterol to phospholipids in erythrocytes suggests a cholesterol turnover imbalance between cell membranes and blood lipoproteins.
Impact:
- Highlights the diagnostic significance of HDL cholesterol levels in assessing leg atherosclerosis severity.
- Suggests that specific types of dyslipoproteinemia may be associated with this condition.
- Provides insights into cellular lipid metabolism disturbances in patients with peripheral artery disease.
Abstract:
Reverse correlation between content of cholesterol in lipoproteins of high density (LPHD) and severity of clinical manifestations was observed in patients with obliterating atherosclerosis of legs. Concentrations of cholesterol, triglycerides and LPHD cholesterol were normal in the majority of patients but dyslipoproteinemia of various types including hypo-alpha-lipoproteinemia, was noted in some patients. The molar ratio "cholesterol/phospholipids" was increased in erythrocytes of the patients examined, demonstrating the disbalance in cholesterol turnover between the cell membranes and blood lipoproteins.
