BACKGROUND/OBJECTIVES: This study investigated the effect of the consumption of carnosine-enriched chicken meat on endothelium-dependent and independent microvascular reactivity and inflammatory mediators in patients with chronic coronary syndrome (CCS).
MATERIALS AND METHODS: In total, 38 CCS participants were randomized to two groups: the Control group (N = 19), who consumed regular chicken meat, and the Carnosine group (N = 19), who consumed carnosine-enriched chicken meat for 3 weeks. Skin microvascular reactivity in response to vascular occlusion (PORH), acetylcholine (ACh ID), sodium nitroprusside (SNP ID), and local thermal hyperemia (LTH) was measured. Arterial blood pressure (BP), heart rate (HR), biochemical parameters, anti- and proinflammatory cytokine levels, and markers of oxidative stress were assessed before and after the intervention.
RESULTS: The consumption of carnosine-enriched chicken meat improved endothelium-dependent (PORH, LTH) and endothelium-independent vasodilation (SNP ID). Systolic BP (SBP), diastolic BP (DBP), and mean BP (MAP), as well as serum concentrations of tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), and endoglin, decreased from the initial measurements.
CONCLUSION: The consumption of carnosine-enriched chicken meat enhances microvascular endothelium-dependent and independent vasodilatation. Patients with CCS can benefit from carnosine-enriched chicken meat consumption through improved hemodynamic parameters, reduced inflammation, and enhanced microvascular relaxation.
