Low levels of the amino acid l-homoarginine are linked to increased cardiovascular risk. Oral supplementation may offer a new strategy for cardiovascular disease prevention, warranting further clinical research.
Area of Science:
- Biochemistry
- Physiology
- Metabolism
Background:
- Epidemiological studies suggest l-homoarginine is a novel cardiovascular risk factor.
- An inverse association exists between homoarginine levels and cardiovascular risk.
- Low homoarginine levels predict higher cardiovascular risk.
Purpose of the Study:
- To review the biochemistry, physiology, and metabolism of l-homoarginine.
- To summarize evidence linking homoarginine to cardiovascular disease.
- To identify research priorities for homoarginine's clinical utility.
Main Methods:
- Review of epidemiological studies.
- Analysis of homoarginine's biochemical and physiological roles.
- Synthesis of existing research on homoarginine and cardiovascular outcomes.
Main Results:
- l-homoarginine is an endogenous amino acid with potential cardiovascular protective effects.
- Low systemic homoarginine levels are associated with increased cardiovascular risk.
- Oral supplementation of homoarginine is a plausible therapeutic strategy.
Conclusions:
- Homoarginine is a promising candidate for cardiovascular risk assessment and treatment.
- Further research is needed to establish homoarginine's role as a prognostic factor and therapeutic target.
- Homoarginine supplementation may represent a novel approach in cardiovascular disease prevention.

Overview of the Cardiovascular System
Heart
The heart is the central pump of the cardiovascular system that circulates blood throughout the body. It comprises two atria receiving the blood and two ventricles pumping blood out of the heart. Their rhythmic contractions, called heartbeats, ensure that blood flow remains continuous.
