Objective:To observe effect of Huoxue Tiaozhi Decoction on blood rheology of blood lipid regulation in coronary heart disease patients after percutaneous coronary intervention（PCI）.Method:With incorporated into standard in 60 cases of PCI patients were randomly divided into observation group and control group

40 cases in each.Two groups of patients after PCI were given aspirin enteric-coated tablets 100 mg

bid

simvastatin tablet:（40 mg

bid）.Observation group was added with Huoxue Tiaozhi Decoction

boiling water service

250 mL/bid.The 2 groups were treated for 1 month as 1 course

2 courses as the treatment.Hemorheology and serum total cholesterol（TC）

triglyceride（TG）

low density lipoprotein（LDL-C）

high density lipoprotein（HDL-C） were observed.Result:The blood high

medium

low shear viscosity

plasma viscosity

hematocrit in treatment group were（3.52±0.62）

（4.33±0.54）

（7.18±1.55）

（1.32±0.14） mPa · s

（34.43±5.54）%;the control group were（3.72±0.58）

（4.52±0.64）

（7.41±1.23）

（1.41± 0.15） mPa · s

（36.78±5.68）%.The two groups after treatment were significantly improved（P<0.05）

and the treat ment group was better than the control group（P<0.05）.TC

TG

LDL-C

HDL-C indexes after treatment in treatment group were（3.61±0.41）

（2.31±0.52）

（3.75±0.38）

（1.95±0.26） mmol · L-1

those in the control group were（3.72±0.58）

（4.52±0.64）

（7.41±1.23）

（1.41±0.15） mmol · L-1.The two groups after treatment were significantly improved（P<0.05）

and the treatment group was better than the control group（P<0.05）.Conclusion:Huoxue Tiaozhi decoction used in coronary heart disease patients after PCI can improve hemorheological paramenters

blood lipids

reduce the incidence of restenosis after PCI.
