Enhancing Endothelial Function with Nutrient-Enriched Table Hen Eggs: A Randomized Study in Patients Recovering from...

Area of Science:

• Cardiovascular Medicine
• Nutritional Science
• Biochemistry

Background:

• Patients with acute coronary syndrome (ACS) are at risk for microvascular dysfunction.
• Dietary interventions may offer a novel approach to improve cardiovascular health in ACS patients.

Purpose of the Study:

• To investigate the effects of consuming table eggs enriched with n-3 polyunsaturated fatty acids (n-3 PUFA), lutein, vitamin E, and selenium on microvascular function, oxidative stress, and inflammatory mediators in patients after ACS.

Main Methods:

• A prospective, randomized, double-blind clinical trial involving ACS patients.
• Participants consumed either enriched (Nutri4) or control hen eggs daily for three weeks.
• Assessed biochemical parameters, antioxidant enzyme activity, oxidative stress markers, and microvascular blood flow responses.

Main Results:

• Nutri4 egg consumption significantly reduced LDL cholesterol and increased serum vitamin E and selenium levels.
• Microvascular reactivity, measured by postocclusive reactive hyperemia (PORH) and acetylcholine-induced dilation (ACh ID), showed marked improvement.
• Enriched eggs enhanced glutathione peroxidase (GPx) and superoxide dismutase (SOD) activity without altering thiobarbituric acid reactive substances (TBARS) or ferric reducing ability (FRAP) values.

Conclusions:

• Consumption of Nutri4 eggs positively influences microvascular function in individuals with ACS.
• This dietary intervention demonstrates a favorable safety profile, with no adverse effects on oxidative stress markers.
