Abstract
In this study we analyzed the concentration of lipoprotein(a) [Lp(a)], PCSK9-Lp(a) complexes and the circulating monocyte subsets in coronary atherosclerosis. 257 patients with coronary atherosclerosis (CA) and 68 patients without stenotic atherosclerosis in the coronary, carotid and lower extremity arteries (control group) were enrolled. Monocyte subpopulations (classical CD14++CD16-, intermediate CD14++CD16+, non-classical CD14+CD16+) were analyzed by direct immunofluorescence and flow cytometry. Lp(a) and PCSK9-Lp(a) complexes in serum were detected by ELISA. The concentration of Lp(a) was higher in CA group compared to controls (23.0 (9.1;73.3) mg/dL versus 10.7 (4.7;25.0) mg/dL, p<0.05). No correlations between the level of Lp(a) and the concentration of PCSK9-Lp(a) complexes, nor between the level of Lp(a) or PCSK9 and the total number of monocytes were observed in both groups. A slight positive correlation between the concentration of PCSK9-Lp(a) complexes and the absolute level of monocytes was obtained (r=0.20, p=0.002) in patients with atherosclerosis predominantly due to intermediate monocyte subsets (r=0.33, p=0.04). According to regression analysis both PCSK9-Lp(a) complex concentration and BMI were related to the absolute number of blood monocytes in patients with atherosclerosis. Further studies are required to determine the pathogenetic contribution of PCSK9-Lp(a) complexes to the development of atherosclerosis.
