Evaluation of proprotein convertase subtilsin /kexin 9(PCSK9) in serum of men hypertensive patients

Abstract

High blood pressure is considered a major factor for the development of heart disease and vascular disease in elderly people, due to higher tension in arteries leading to hypertension. PCSK9 is a proprotein convertase that increases circulating LDL levels by directing hepatic LDL receptors into lysosomes for degradation. The effects of PCSK9 on hepatic LDL receptors and contribution to atherosclerosis via the induction of hyperlipidemia are well defined. Methods: The case-control study included (90) subjects divided into sixty (60) male patients. Samples were collected for patients with high blood pressure in Al-Sadr Medical City in Najaf Al-Ashraf / Iraq, and laboratory tests were conducted to measure the lipid profile in Al-Sadr Medical City laboratories. Height and weight were measured, and other information was also collected. The ELISA test was performed in the advanced animal laboratory in the college’s Department of Biology. Department of Science/University of Kufa. The study was conducted by collecting samples and measuring all factors in the period from 1/11/2023 to 2/2/2024. A control group study of 30 men was also conducted. All groups that appeared healthy were matched in age, and patients with diabetes, kidney disease and heart disease were excluded from the study, as well as any other systemic diseases. Conclusion: The present study concluded that PCSK9considered as a prognostic marker for prediction of hypertension. Also, PCSK9 was very related in hypertensive patients with hyperlipidemia (cholesterol, TG, LDL, & HDL). High biomarker level associated with ages especially at new diagnosis without treatment and with short duration of disease. Smoking plays important roles with high a level of PCSK9 in hypertensive patients. The genetic may play a role in present study by high level of This biomarker in familial hypertensive patients. Obesity has a crucial role in in hypertensive patients with high PCSK9 level.
