RESUMO
@#Objective The plasma von Willebrand factor(vWF)level in patients with primary microvascular angina(PMVA)were measured to evaluate the vascular endothelial function of the patients.The change of vWF level in patients after the treatment with Shexiangbaoxin Pill were observeg.Methods Totally 69 patients who were definitely diagnosed as PMVA,They were randomly divided into conventional treatment group(33cases)and ShexiangBaoxin Pill group(36cases).The plasma vWF levels of the two groups were measured before and after treatment.Results The level of vWF before treatment in conventional treatment group was(50.93±32.98)μg/L.The level of vWF before treatment in ShexiangBaoxin Pill group was(27.45±25.02)μg/L.The level of vWF in conventional treatment group after treatment was(49.65±35.12)μg/L.The level of vWF after treatment in ShexiangBaoxin Pill group was(17.37±15.68)μg/L.The difference of vWF decrease in Baoxin Pill group after treatment(10.08±16.47)μg/L,was lower than that in conventional treatment group(1.28±12.37)μg/L,the difference is significant(P<0.05).Conclusion Shexiang Baoxin Pill has the function of protecting vascular endothelium,and PMVA patients can benefit from treatment.
