Alcohol consumption, cardiovascular health, and endothelial function markers

Area of Science:

• Cardiology
• Biochemistry
• Public Health

Background:

• Cardiovascular diseases (CVDs) are a leading cause of mortality and reduced quality of life globally.
• Diet and lifestyle significantly impact cardiovascular health, with alcohol consumption being widespread.
• Alcohol exhibits paradoxical effects on cardiovascular health, necessitating an understanding of underlying biochemical pathways.

Purpose of the Study:

• To investigate the biochemical mechanisms through which ethanol influences cardiovascular health.
• To explore the role of the vascular endothelium in mediating alcohol's effects.
• To identify potential alternatives to alcohol that mimic its beneficial cardiovascular effects without adverse consequences.

Main Methods:

• Review of biochemical pathways affected by ethanol, including oxidative stress, lipoproteins, and insulin resistance.
• Analysis of endothelial markers such as nitric oxide, endothelin-1, and inflammatory cytokines.
• Examination of the relationship between alcohol consumption patterns and cardiovascular health outcomes.

Main Results:

• Ethanol impacts the vascular endothelium through pathways involving oxidative stress, lipoproteins, and insulin resistance.
• Alcohol-induced endothelial changes are linked to markers like nitric oxide, endothelin-1, inflammatory cytokines, and hemostatic factors.
• The dose-response relationship between alcohol and cardiovascular health appears J-shaped, but clinical evidence for recommending alcohol consumption is insufficient.

Conclusions:

• Ethanol exerts complex, dose-dependent effects on cardiovascular health, mediated by the vascular endothelium.
• While low ethanol doses may show biochemical benefits, risks like addiction and other adverse effects preclude recommendations for non-drinkers.
• Further research is needed to identify non-alcoholic substances that replicate the cardiovascular benefits of moderate alcohol consumption.
