    Abstract:
    OBJECTIVE: To investigate the changes of high-sensitive C-reactive protein (hs-CRP) and monocyte chemotactic factor-1 (MCP-1) following percutaneous coronary interventional procedures (PCI) in patients with coronary artery disease (CAD), and evaluate the impact of PCI on the inflammatory indices and postoperative vascular restenosis. METHODS: This study involved 80 patients undergoing PCI procedures for CAD compromising a single coronary artery. Forty healthy individuals with normal findings by coronary angiography were selected as the control group. Before and after PCI or coronary angiography, plasma hs-CRP and MCP-1 were measured in all the subjects by immunonephelometry and enzyme-linked immunosorbant assay (ELISA), respectively. RESULTS: In the CAD patients, the plasma hs-CRP level was significantly elevated after PCI as compared with the preoperative level (2.37-/+0.56 microg/L vs 1.59-/+0.41 microg/L, P<0.01), whereas in the control group, the hs-CRP level underwent no significant changes after coronary angiography (1.18-/+0.37 microg/L vs the preoperative level of 1.13-/+0.32 microg/L, P>0.05). PCI procedures also resulted in significant elevation of plasma MCP-1 level in the CAD patients (26.04-/+5.43 pg/L vs the preoperative level of 18.07-/+4.30 pg/L, P<0.01), but in the control group, MCP-1 showed no significant variation after coronary angiography (9.80-/+2.64 pg/L vs the preoperative level of 9.63-/+2.52 pg/L, P>0.05). CONCLUSION: Plasma hs-CRP and MCP-1 are elevated in CAD patients following PCI procedures, but their roles in the vascular restenosis following the procedures need further investigation.
