We investigated whether serum monocyte chemoattractant protein-1 (MCP-1) level predicted coronary atherosclerotic burden in patients with stable coronary artery disease and its relationship with coronary collateral grade.


We prospectively included 196 patients (103 males, 93 females; mean age 59 ± 11 years) who underwent coronary angiography for stable angina pectoris. Serum MCP-1 levels were determined before coronary angiography. Coronary atherosclerotic burden was measured by the Gensini score, and coronary collateral development was assessed by the Rentrop classification. The patients were divided into four groups: those with normal coronary arteries (NCA); those with coronary lesions of <70% luminal obstruction; and those with coronary lesions of ≥ 70% luminal obstruction accompanied by a good or poor collateral grade.


The mean serum MCP-1 level was higher in patients with coronary lesions compared to patients with NCA (129 ± 130 vs. 102 ± 55 pg/ml, p=0.048). Although there were no significant differences in the MCP-1 levels of patients with NCA, with <70% luminal obstruction, and those with a significant luminal obstruction and a poor collateral grade, patients with significant luminal obstruction and a good collateral grade had significantly higher MCP-1 levels compared to the remaining groups (p=0.016). However, in multivariate regression analysis, MCP-1 level was not independently associated with the Gensini score.


Our findings suggest that serum MCP-1 level is higher in patients with coronary atherosclerosis, without a significant and independent association with coronary atherosclerotic burden. Significantly increased serum MCP-1 levels in patients with a good collateral grade may be an interesting issue of investigation.
