Amino Acids in Circulatory Function and Health.

Area of Science:

• Cardiovascular Physiology and Pathology
• Amino Acid Metabolism

Background:

• Cardiovascular disease is a leading cause of global mortality.
• Amino acids play a critical role in cardiovascular health and disease.
• Specific amino acids like L-arginine, L-glutamine, L-tryptophan, and L-cysteine impact vascular function.

Purpose of the Study:

• To review the multifaceted roles of amino acids and their metabolites in cardiovascular physiology and pathology.
• To explore the therapeutic potential of amino acid-based interventions for vascular diseases.
• To discuss limitations of current approaches and propose novel strategies.

Main Methods:

• Literature review of studies on amino acids and cardiovascular disease.
• Analysis of mechanisms by which amino acids and metabolites affect vascular homeostasis.
• Evaluation of clinical and preclinical data on amino acid supplementation.

Main Results:

• Amino acids and their metabolites regulate vascular cell processes, exert antioxidant and anti-inflammatory effects, and mitigate cardiovascular risk factors.
• Certain amino acid metabolic pathways can paradoxically promote vascular disease.
• Monotherapy with amino acids has shown limited clinical success.

Conclusions:

• A holistic approach targeting multiple amino acid derangements is necessary for effective vascular disease treatment.
• Combined amino acid supplementation with other agents or using amino acid metabolites may offer superior therapeutic benefits.
• Further research into amino acid-derived metabolites and combined therapies is warranted.
