The tested MCP-1 -2518 (A/G) SNP, concretely the presence of the mutant G allele, statistically significantly correlated with the higher serum level of hsCRP in patients with IHD (P = .016), AP (P = .004), and HT (P = .013), and in all cases higher correlations were found in men (Table 3). Here, CCL2 is linked to hematocrit.
