Association of Fibronectin, Leptin and LDL-Oxide Serum Levels With Coronary Artery Disease in Non-smoker and Non-diabetic Patients

Coronary artery disease (CAD) is a leading cause of death of women and men worldwide. Endothelial dysfunction, smoker, diabetic, cell adhesion and oxidative stress may be considered as novel risk factors of CAD. These materials are cooperative events involved in atherosclerosis development. In the present study the serum levels of fibronectin, leptin and LDL-oxide were investigated in patients of CAD including non-smoker and non-diabetic with control group. Measurement of these parameters helps to prevent and treat the disease. In this study we measured serum levels of fibronectin, leptin and LDL-oxide in 200 individuals including 100 patients with CAD and 100 individuals as control group. Also patients with malignancy, renal and liver diseases and other disease were excluded from the study. Serum leptin and fibronectin were measured by enzyme-linked immunosorbent assay (ELISA) method using kits from German Imediagnostic and Chinese Crystal Day companies, respectively. Moreover, ELISA procedures were used to determine the serum LDL-oxide. The serum levels of fibronectin, leptin and LDL-oxide were increased significantly as compared to control group (P ≤ 0.05 in all cases). It seems that there was strong (+) correlation between fibronectin, leptin and LDL-oxide in CAD. It was concluded that endothelial dysfunction, cell adhesion and stress oxidative are cooperative events involved in atherosclerosis development. Fibronectin, leptin and LDL-oxide have become greatly important in pathogenesis of CAD. Association between fibronectin, leptin and stress oxidative suggest that their involvement in development of atherosclerosis can be used as detective measure.
