Homocysteine Attack on Vascular Endothelium-Old and New Features

Area of Science:

• Cardiovascular Science
• Biochemistry
• Medical Research

Background:

• Homocysteine (Hcy) is an established risk factor for cardiovascular disease (CVD).
• Elevated plasma total homocysteine (hyperhomocysteinemia) is increasingly linked to endothelial dysfunction, inflammation, and atherogenesis.
• Endothelial dysfunction plays a key role in regulating physiological and pathophysiological processes.

Purpose of the Study:

• To review existing literature on the direct link between endothelial injury and elevated homocysteine levels.
• To identify current evidence, describe novel mechanisms, and explore potential therapeutic strategies.
• To address ongoing debates and highlight the need for further research in homocysteine's role in health and disease.

Main Methods:

• Literature review of clinical and experimental studies.
• Analysis of data demonstrating the association between homocysteine and cardiovascular disease risk.
• Examination of mechanisms underlying homocysteine-induced endothelial dysfunction.

Main Results:

• Homocysteine is a significant marker of overall vascular damage.
• Abnormally high homocysteine concentrations contribute to endothelial dysfunction and inflammation.
• Dietary and lifestyle modifications are recommended for managing hyperhomocysteinemia.

Conclusions:

• There is a direct correlation between endothelial injury and increased homocysteine levels.
• Early monitoring and control of homocysteine are essential for cardiovascular health.
• Further research is needed to refine therapeutic strategies for hyperhomocysteinemia and its impact on CVD.
