Study of oxidative stress and trace element levels in patients with alcoholic and non-alcoholic coronary artery disease.

Alcohol consumption induces oxidative stress, and leads to lipid peroxidation. These effects have been linked to alcohol-related toxicity and diseases are considered relevant to alcohol-atherosclerosis interrelationship. Deficiency of many antioxidants and trace elements may impair the antioxidant defense leading to ethanol induced oxidative stress. In the present study, our aim was to investigate the lipid peroxidation, lipid profile, antioxidant enzymes and trace elements in patients with and without alcoholic coronary artery disease (CAD). Our study included 61 patients suffering from CAD, 124 patients suffering from alcoholic CAD with high to moderate alcohol intake, 75 controls were randomly selected for our study. Increased serum lipid peroxidation, total cholesterol, triglycerides, LDL cholesterol and copper levels were high while levels of HDL cholesterol, glutathione peroxdiase, superoxide dismutase, trace elements like Selenium and Zinc were low in high alcoholic CAD patients compared with moderate and non alcoholic CAD patients. The results obtained from present study indicate that high alcohol intake predicts low antioxidant enzyme and that trace element may contribute to the increased susceptibility for the development of CAD.
