ABSTRACT
We studied serum content of some polyunsaturated fatty acids and their correlations with parameters of oxidative stress (FORT), antioxidant protection (FORD), lipoprotein-associated phospholipase A2 (LP-PLA2), and serum level of LPO products in male patients with coronary atherosclerosis. The mass fraction of polyunsaturated fatty acids and FORD were lower, while LP-PLA2, FORT, and concentration of LPO products were higher than in the control group (conventionally healthy men). Negative correlations of medium strength of polyunsaturated fatty acids with inflammation markers and oxidative stress were revealed, which can indicate that the decrease in polyunsaturated fatty acids content is associated with enhanced generation of free radicals, and consequently with increased risk of early atherosclerosis development.

We studied the balance of fatty acids and their correlation with parameters of lipid metabolism and inflammation markers in men with coronary atherosclerosis. In the blood of patients and healthy men, the content of myristic (C14:0), pentadecanoic (C15:0), palmitic (C16:0), stearic (C18:0), arachidic (C20:0) and docosanic (C22:0), TNFα, IL-1ß, IL-6, IL-8, C-reactive protein, cholesterol, triglycerides, HDL, and LPO intensity were measured. In patients with coronary atherosclerosis, increased concentrations of saturated fatty acids, triglycerides, LPO products, IL-6, IL-8, and C-reactive protein were found. Correlation analysis revealed multiple correlations between the studied fatty acids, correlation of C16:0, C18:0, and C20:0 with inflammation markers, C14:0, C16:0, and C18:0 with triglyceride level, C16:0, C18:0, and C20:0 with cholesterol. The contents of C14:0, C15:0, C16:0, and C18:0 correlated with the presence of coronary atherosclerosis. Lipid metabolism disturbances in coronary atherosclerosis were accompanied by changes in not only lipid spectrum and inflammation markers, but also fatty acids balance.
