Bioactive Flavonoids in Protecting Against Endothelial Dysfunction and Atherosclerosis

Area of Science:

• Cardiovascular Science
• Pharmacology
• Nutritional Science

Background:

• Atherosclerosis is a cardiovascular disease linked to hyperlipidemia and inflammation.
• Endothelial dysfunction, characterized by impaired vasodilation and oxidative stress, is a key predisposing factor.
• Endothelial dysfunction involves oxidative stress, inflammation, leukocyte adhesion, and endothelial-mesenchymal transition (EndoMT).

Purpose of the Study:

• To review the protective effects of flavonoids against atherosclerosis initiation and progression.
• To highlight the mechanisms by which flavonoids impact endothelial cells.
• To discuss the antioxidant, anti-inflammatory, anti-thrombotic, and lipid-lowering properties of flavonoids.

Main Methods:

• Literature review of scientific studies on flavonoids and atherosclerosis.
• Analysis of flavonoid mechanisms targeting endothelial cell functions.
• Synthesis of evidence on flavonoid's impact on oxidative stress, inflammation, and lipid metabolism.

Main Results:

• Flavonoids exhibit antioxidant activity by neutralizing reactive oxygen species (ROS), preventing LDL cholesterol oxidation.
• Flavonoids possess anti-inflammatory properties, reducing cardiovascular risk.
• Flavonoids improve vascular function, reduce platelet aggregation, and alleviate ischemic damage.

Conclusions:

• Flavonoids demonstrate significant protective effects against atherosclerosis via endothelial cell modulation.
• Their antioxidant, anti-inflammatory, and anti-thrombotic actions are crucial.
• More clinical evidence is required to establish optimal dosages and therapeutic applications for atherosclerosis treatment.
