Atherogenesis: a postprandial phenomenon.

D B Zilversmit

    Circulation
    |September 1, 1979
    PubMed
    Summary
    This summary is machine-generated.

    Dietary cholesterol may promote atherosclerosis by increasing atherogenic chylomicron remnants in the blood. Arterial cells uptake these remnants, potentially causing disease during the postprandial period, even without familial hyperlipoproteinemia.

    Area of Science:

    • Cardiovascular Science
    • Lipid Metabolism
    • Atherosclerosis Research

    Background:

    • Plasma chylomicrons are investigated for their role in atherosclerosis.
    • Cholesterol-rich diets are a potential risk factor for cardiovascular disease.

    Purpose of the Study:

    • To evaluate the atherogenic potential of plasma chylomicrons after cholesterol-rich meals.
    • To explore the uptake of chylomicron remnants by arterial cells.

    Main Methods:

    • Review of evidence on lipoprotein uptake by arterial cells in humans and animals.
    • Discussion of research directions for evaluating chylomicron remnants as a risk factor.

    Main Results:

    • Chylomicron remnants, alongside low-density lipoproteins, are taken up by arterial cells.

  • Atherogenesis may occur postprandially in individuals without familial hyperlipoproteinemia.

    • Conclusions:

    • Chylomicron remnants are implicated in atherogenesis, particularly after high-cholesterol intake.
    • Further lipoprotein studies post-test meals are crucial for risk assessment.
