According to the univariate regression analysis, the relative risk of early IHD among the subjects with AO is significantly associated with lower blood concentrations of such cytokines/chemokines as GM-CSF (OR = 0.873, CI 0.763–0.999, p = 0.049) and MCP-1 (OR = 0.997, CI 0.995–0.999, p = 0.027). The gene discussed is CCL2; the disease is myocardial ischemia.
