Effect of Danhong Injection on Platelet Activation and Inflammatory Factors in Patients of Acute Coronary Syndrome after Intervention Therapy

Objective To explore the effect of Danhong Injection (DHI) on platelet activation and inflammatory factors in patients of acute coronary syndrome (ACS) after intervention therapy. Methods One hundred ACS patients were randomly assigned to the DHI group and the control group equally. Both were treated with the conventional treatment,including aspirin,clopidogrel,β-receptor blocker,angiotensin converting enzyme inhibitor,etc. for 2 weeks after percutaneous coronary intervention (PCI),and to the patients in the DHI group,intravenous dripping of DHI was given simultaneously. Fasting venous blood of patients were collected before PCI and on the next morning of PCI to determine the platelet activation indices,expression of CD62p and receptor complex of glucose protein (GP)Ⅱb/Ⅲa by flow cytometry;plasma fibrinogen C (FIB-C) by scattering turbidimetry,and serum high-sensitivity C-reactive protein (hs-CRP) with emulsoid immuno-enhancing turbidimetric test kit. The outcomes were compared with those determined in 40 healthy persons for control. Results Serum levels of CD62p,GPⅡb/Ⅲa,FIB-C and hs-CRP in ACS patients were significantly higher than those in the healthy control (all P0.01),and those were significantly higher after PCI than before PCI (P0.05 or P0.01). After being treated for 2 weeks,the 4 platelet activation indices were lowered to different extent in both groups,but the lowering in the DHI group was more significant than that in the control group (P0.05). Conclusion DHI can inhibit the platelet activation and inflammatory reaction in ACS patients after PCI.
