Dietary artichoke juice supplementation improved endothelial function in hyperlipidemic patients. Artichoke juice reduced cholesterol and improved brachial flow-mediated vasodilation, indicating a positive effect on vascular health.

Area of Science:

  • Cardiovascular Research
  • Nutritional Science
  • Pharmacology

Background:

  • Endothelial dysfunction is an early sign of atherosclerosis.
  • Artichoke extracts possess cholesterol-lowering and antioxidant properties.
  • Brachial flow-mediated vasodilation (FMV) and adhesion molecules (VCAM-1, ICAM-1, E-selectin) are key markers of endothelial function.

Purpose of the Study:

  • To evaluate the impact of dietary artichoke juice on brachial FMV in hyperlipidemic individuals.
  • To assess changes in serum lipids and endothelial markers following artichoke supplementation.

Main Methods:

  • 18 hyperlipidemic patients received 20 ml/day of artichoke juice for 6 weeks.
  • Serum lipids, VCAM-1, ICAM-1, E-selectin, and brachial FMV were measured at baseline and after 6 weeks.

  • A control group of 10 hyperlipidemic patients received standard care.

    • Main Results:

    • Artichoke treatment led to reduced total and LDL cholesterol, and increased triglycerides.
    • Significant reductions in VCAM-1 and ICAM-1 were observed post-artichoke intervention.
    • Brachial FMV significantly increased after artichoke supplementation, unlike in the control group.
    • Changes in VCAM-1 and ICAM-1 correlated with improvements in brachial FMV.

    Conclusions:

    • Dietary supplementation with artichoke juice positively influences endothelial function in hypercholesterolemic patients.
    • Artichoke juice may be a beneficial adjunct therapy for managing endothelial dysfunction associated with hyperlipidemia.
