Abstract

Chemokine-driven migration of inflammatory cells has been implicated in pathogenesis of atherosclerosis-associated conditions such as ischemic stroke and myocardial infarction. In this study, a candidate chemokine, monocyte chemoattractant protein MCP-1, was investigated in patients with both aforementioned manifestations of atheroslerotic inflammation. MCP-1 levels in serum were determined by ELISA in 40 healthy, control subjects C, 40 patients with ischemic stroke IS, and in 64 patients with myocardial infarction MI. Statistical analysis utilised Mann-Whitney test, Fisher-s exact test, and Spearman-s rank correlation P<.05. In comparison to control subjects C; median-interquartile range: 239-126 pg-mL, MCP-1 serum levels were increased in both investigated patient cohortsIS: 384-370, P<.001; MI: 360-200, P<.002. There was a substantial variability of MCP-1 serum levels, especially in theIS group. No relationship was observed between chemokine levels and atherosclerosis risk factors hypertension, diabetes, smoking, and alcohol consumption, and MCP-1 was also not related to age or gender. Elevation of MCP-1 in circulation of patients with atherosclerosis-associated complications implicates this CC chemokine ligand CCL2 in inflammatory processes, which contribute to pathogenesis of myocardial infarction and ischemic stroke. Further investigations, including patient stratification, are however necessary to evaluate if MCP-1 can be utilised for clinical management of patients with these diseases.
