[Markers of inflammation--monocyte chemoattractant protein-1 (MCP-1) and C-reactive protein--in blood of patients with unstable angina pectoris and stable effort angina].

AIM: To estimate concentrations of C-reactive protein (CRP) and MCP-1 in blood plasma of patients with unstable angina (UA) and stable effort angina (SEA).

MATERIAL AND

METHODS

Multiprojection coronaroangiography was performed in 12 patients with UA and 11 patients with SEA. Hemodynamically significant stenosis (50% and more) at least in one major coronary artery was confirmed in all the patients. CRP and MCP-1 were measured with latex agglutination and enzyme immunoassay (Biosource kits), respectively.

RESULTS

UA patients had significantly higher plasma levels of MCP-1 and CRP than those with SEA (107.25 +/- 16.19 vs. 63.0 +/- 16.16 pg/ml and 1.99 +/- 1.64 vs 0.44 +/- 0.28 mcg/ml, respectively).

CONCLUSION

Estimation of MCP-1, as a marker of vascular wall inflammation, can be used, in line with other indices, for verification of UA.
