Aim. We study the dynamics of oxidatively modified low-density lipoprotein (ox-LDL) content in blood plasma, as well as changes in the activity of key antioxidant enzymes such as Se-containing glutathione peroxidase (GSH-Px) Cu,Zn-superoxide dismutase (SOD) and catalase in erythrocytes of patients with coronary artery disease during treatment with PCSK9 inhibitor (ewolocumab). Materials and methods. The study included 9 men (59 ± 10 years) with coronary artery disease with atherosclerotic lesion at least one main coronary artery according to coronary angiography. Patients took standard therapy before taking the study, everyone took the maximum tolerated dose of statins. Since the target cholesterol levels of low-density lipoprotein cholesterol (LDL-C) were not achieved during the statin therapy, patients were prescribed lipid-lowering therapy with the inclusion of the inhibitor PCSK9-emocoucumab from Amgen 420 mg once a month. The content of lipid metabolism indices was determined by standard biochemical methods. The level of ox-LDL in the blood plasma was determined by the immunochemical method. The activity of antioxidant enzymes was determined in blood erythrocytes using biochemical techniques Results. Cholesterol-lowering drug of the new type - inhibitor protein convertase subtilisin/kexin type 9 (PCSK9) evolocumab (Amgen) not only effectively lowers the level of cholesterol in low density lipoprotein (LDL), but also significantly reduces the content of oxdatively modified LDL in blood plasma. Unlike statins, the inhibitor of PCSK9 does not cause a decrease in the activity of antioxidant enzymes of the blood. Conclusion. PCSK9 inhibitor has no effect on the parameters of oxidative stress.
