    Journal: Clin Chim Acta; 1992 Oct 15; 211(1-2):101-12. PubMed ID: 1468149.
    Abstract:
    Lipid peroxides in plasma were determined in 100 patients with coronary artery disease, in 100 patients with peripheral artery disease and in 100 persons without any clinical symptoms of coronary or peripheral artery disease. The concentrations of lipid peroxides were significantly higher in patients with atherosclerosis (both coronary and peripheral arteries) than in controls. There was no difference between lipid peroxides in patients with coronary and peripheral artery disease. Lipid peroxides in plasma were similar in subgroups of patients with coronary artery disease without a history of myocardial infarct and those who had had myocardial infarct. In subgroups of patients with peripheral artery disease divided according to the severity of peripheral atherosclerosis a positive association between the concentration of lipid peroxides in plasma and the severity of disease was observed. In all groups there was a significant correlation between the age of examined persons and lipid peroxides in plasma; however, the concentration of lipid peroxides in plasma was statistically higher in patients with atherosclerosis than in the control age matched group. The correlation between lipid peroxides and total cholesterol as well as triglycerides were weak and not statistically significant in most of the examined groups. The results of this study provide clinical support for experimental data indicating that peroxidation of lipids is an important factor in the formation of atherosclerotic changes. They also indicate that determination of plasma lipid peroxides may give important supplementary information in monitoring patients with clinical symptoms of atherosclerosis.
