Objective:To observe the therapeutic effects of Guizhi Fuling decoction(GFD) and Huanglian Jiedu decoction(HJD) on patients with unstable angina(UA). Method: Seventy-two UA patients were randomly assigned to the treatment group(36 cases) and the control(36 cases). All were treated by the regular UA treatment

but to patients in the treatment group

GFD and HJD was given additionally. The course of treatment was three weeks. Before and after the treatments

changes of clinical symptoms

24-hour ambulatory electrocardiogram(AECG)

blood lipids and serum levels of high-sensitivity C-reactive protein(hs-CRP) were observed. Result: Compared with before treatment

obvious improvement of clinical symptom and experiment index was obtained in two groups. After treatment

the frequency of angina attacks

myocardial ischemia times in 24 h

the longest duration of a single myocardial ischemia

the total duration of myocardial ischemia in 24 h and hs-CRP were reduced and high density lipoprotein cholesterol(HDL-C) was increased further in the treatment group(P<0.05). Conclusion: GFD and HJD showing definite effects on UA.
