CCL2 and cardiomyopathy: In the group of CHD patients without cardiomyopathy, positive correlations were found between the level of MCP-1 and EPCs in the sinus blood (rs = 0.72; n = 10; p < 0.05), the concentration of MCP-1 and VEGF-A in the sinus blood (rs = 0.53; n = 15; p < 0.05) and MCP-1 in sinus and peripheral blood (rs = 0.72; n = 23; p < 0.001), as well as between peripheral blood parameters: MCP-1 and VEGF-A (rs = 0.47; n = 18; p < 0.05), VEGF-A and VEGF-B (rs = 0.90; n = 13; p < 0.001), SDF-1 and VEGF-A (rs = 0.76; n = 13; p < 0.01) and SDF-1 and VEGF-B (rs = 0.65; n = 13; p < 0.05) (Figure 3A).
