Disturbance In The Composition of Lipoprotein Particles And Chronic Inflammation As Prognostic Factors In The Development of Coronary Disease
The study focused on 30 dyslipidemic patients (12 women and 18 men); 16 of them had coronary disease (CD). The concentrations of apoA and apoB were determined in all patients, as well as the calculated ratio between apoA and apoB. As far as inflammatory indicators are concerned, the concentrations of sensitive C reactive protein (hsCRP), albumin, fibrinogen, intracellular adhesive molecule (ICAM-1) and vascular adhesive molecule (VCAM -1) were determined. In patients with CD there were considerably higher concentrations of fibrinogen (3.1 ± 1.2 vs. 2.7 ± 0.7 g/L) and VCAM-1 (10.9 ± 3.6 vs. 8.3 ± 2.8 g/L) (p<0.05) while the numerical values of hsCRP and ICAM-1 were not significantly different in relation to the patients without CD. The concentration of apoB and the value of apoB/apoA ratio were considerably higher in patients with CD (1.7 ± 0.8 vs. 1.3 ± 0.4 and 1.3 ± 0.4 vs. 0.9 ± 0.4; p<0.05), whereas the concentration of apoA did not differ in relation to the patients without CD. The research confirmed the significance of the disturbance in the composition of lipoprotein particles and the systemic inflammatory response in the pathogenesis of atherosclerosis, whereas their significant mutual connection was not shown. This indicates their cumulative effect and different mechanisms at the base of these disturbances.
