Objective:To observe the curative effect of Sini Decoction in adjuvant treatment of angina pectoris of coronary heart disease with cold congealing heart vessel type.Methods:Seventy-six cases were randomly divided into group A and group B,with 38 cases in each group.Both groups were treated with conventional western medicine combined with Danhong Injection for angina pectoris,and group B were treated with modified Sini Decoction in addition.Results:The total effective rate of group B was higher than that of group A(P<0.05).After treatment,the attack and duration of angina pectoris in group B were shorter than those in group A,while TG,TC and LDL-C were lower than those in group A(P<0.05).After treatment,the SAQ score and HDL-C increased in both groups(P<0.05),and those in group B were higher than those in group A(P<0.05).Conclusion:Modified Sini Decoction could improve the curative effect in adjuvant treatment of angina pectoris of coronary heart disease with cold congealing heart vessel type.
