[Blood and plasma hyperviscosity in primary hyperlipidemia].

P Ozanne, D Boudart, F Mainard

    La Revue De Medecine Interne
    |March 1, 1984
    PubMed
    Summary

    Hyperlipidemic patients show increased plasma and blood viscosity. This elevation correlates more with triglyceride levels than cholesterol, potentially explaining clinical differences between hypertriglyceridemia and hypercholesterolemia.

    Area of Science:

    • Rheology
    • Biomedical Engineering
    • Clinical Biochemistry

    Context:

    • Hyperlipidemia (HLP) is a condition characterized by elevated levels of lipids in the blood.
    • Understanding hemorheological changes in HLP is crucial for assessing cardiovascular risk.
    • Previous studies have indicated potential alterations in blood flow properties in HLP.

    Purpose:

    • To investigate and compare plasma and blood viscosity in hyperlipidemic patients versus healthy controls.
    • To determine the correlation between viscosity changes and specific lipid profiles (triglycerides and cholesterol).

    Summary:

    • Plasma and blood viscosities were significantly elevated in 15 hyperlipidemic patients compared to 10 healthy volunteers.
    • Viscosity measurements were conducted at 25°C using a couette-type viscosimeter.
    • The increased viscosity in HLP patients showed a stronger correlation with triglyceride levels than with cholesterol levels.

    Impact:

    • Findings suggest that elevated triglyceride levels contribute more significantly to hemorheological changes in hyperlipidemia.
    • This correlation may offer a partial explanation for the distinct clinical manifestations observed in hypertriglyceridemia versus hypercholesterolemia.
    • The study highlights the importance of considering rheological parameters in the clinical management of hyperlipidemia.
