Effect of "Qishen Yiqi Droplet"on Inflammatory Factors in Patients With Acute Coronary Syndrome After Percutaneous Coronary Intervention / 中国循环杂志

ABSTRACT

Objective:To observe the effect of "Qishen Yiqi Droplet" on serum concentrations of high sensitivity C reactive protein(hs-CRP),plasminogen activator inhibitor-1(PAI-1),endothelin-1(ET-1)in patients with acute coronary syndrome(ACS)after percutaneous coronary intervention (PCI).Methods:A total of 100 consecutive ACS patients ready to receive PCI therapy in our hospital from june 2007 to August 2008 were randomly assigned into two groupsQishen group,n=50,with Qishen Yiqi Droplet 5.0 g three timee a day+conventional therapy after PCI;and Control group,n=50 with conventional therapy after PCI.The concentrations of hs-CRP,PAI-1 and ET-1were detected and compared 24 hours before PCI,and 24 hours,4weeks after PCI between two groups respectively.Results:There were no obvious differences of hs-CRP,PAI-1 and ET-1 24 hours after PCI in two groups.The levels of hs-CRP,PAI-1,ET-1 were lower in Qishen group than in Control group 4 weeks after PCI (0.219±0.143)ng/dl vs.(0.366±0.132)ng/dl,P<0.001,(104.252±26.038)ng/dl vs.(118.419±28.849)ng/ml,P<0.05,and (37.411±12.977)ng/dl vs.(45.755±12.305)pg/ml,P<0.01,respectively.Conclusion:Qishen Yiqi Droplet could decrease the levels of hs-CRP,PAI-1 and ET-1 in ACS patients who underwent PCI,and it might have the protective role in preventing the neointimal hyperplasia and thrombogenesis after stent implantation.
