ABSTRACT
Objective: To investigate the effects of domestic bivalirudin on plasma intercellular adhesion molecular-1 (ICAM-1) during percutaneous coronary intervention (PCI).Methods: Sixty PCI candidates were randomly divided into heparin group (n =30) and bivalirudin group (n =30).They were respectively treated with intravenous heparin and domestic bivalirudin as the anticoagulants during PCI.ICAM-1 in blood was measured before PCI and in 2h, 1d and 7d after PCI, respectively.Results: In heparin group, ICAM-1 level decreased significantly in 2 h after the intravenous injection when compared with that before the injection and that in bivalirudin group at the same time point (P＜0.05).No significant differences in ICAM-1 level were found on the 1st and 7th day after PCI in the two groups when compared with that before the administration (P＞0.05).Mild bleeding occurred in three patients receiving heparin and one patient receiving bivalirudin,but there was no significant difference after PCI.Conclusion: Compared with bivalivudin, heparin has a short inhibitory effect on the expression of ICAM-1 during PCI.It is beneficial to the patients with kidney disease or stroke during PCI.
