Objective: The purpose is to study the curative effect of Zhilong Huoxue capsule on unstable angina (UA) and its influence on vascular endothelial function and platelet function. Method: Eighty cases of UA patients were randomly divided into control group (40 cases) and observation group (40 cases) according to digital method. Patients in both groups were given conventional treatment. Patients in control group took Fufang
1.2 g·d-1
3 times/day
orally. Patients in observation group took Zhilong Huoxue capsule
1.2 g·d-1
3 times/day
orally. Treatment course was 8 weeks. The condition of angina pain occurring was observed. The nitroglycerin dosage and the syndrome integral and Qi deficiency syndrome of blood stasis were recorded. Levels of flow mediated vasodilation (FMD)
plasma endothelin (ET)
nitric oxide (NO)
von willebrand factor (vWF) and platelet α-membrane particles protein (GMP-140) were detected. Result: The total effective rate of observing group was 92.5%
superior to 72.5% of the control group (P<0.05). The total effective rate of electrocardiogram curative effect of observation group was 90.0%
superior to 75.5% in the control group (P<0.05). After treatment
the anginal attacks and nitroglycerin consumption of observation group were less than the control group (P<0.01). The FMD and NO of observation group were higher than the control group (P<0.01)
while the ET and vWF of observation group lower than the control group (P<0.01). GMP-140 level of observation group was lower than the control group (P<0.01). The Qi deficiency syndrome of blood stasis score of observation group was lower than the control group (P<0.01). Conclusion: Zhilong Huoxue capsule can improve the UA patients' clinical symptoms and clinical curative effect and decrease the nitroglycerin dosage and the times of angina pain occurring. Its mechanism may be related to improve the function of vascular endothelium and platelet and thus improving vasodilatation function
microcirculation status and increasing myocardial oxygen supply.
