An observation on therapeutic effect of combined traditional Chinese and western medicine for treatment of microvascular angina / 中国中西医结合急救杂志

ABSTRACT

Objective To observe the clinical effect of Shexiang Baoxin pill,a traditional Chinese medicine,combined with nicorandil on microvascular angina pectoris.Methods Seventy patients with microangiopathic angina diagnosed by coronary angiography admitted to the First Affiliated Hospital of Baotou Medical College from January 2014 to August 2016 were enrolled,and they were divided into a control group and an observation group according to conplete random number table method,35 patients in each group.Both groups were given routine treatment,in the observation group,additionally,nicorandil 5 mg 3 times a day and 2 Shexiang Baoxin pills (22.5 mg per tablet),3 times a day were orally applied,the therapeutic course in both groups being 6 weeks.Before and after treatment,the changes of number of episodes of angina pectoris per week,of the total number of ST-segment depression leads and the minimum voltage amplitude of ST-segment depression in the 12-lead resting electrocardiogram and adverse reaction were observed in the two groups.Results The frequency of angina pectoris after treatment was less than that before treatment,the total number of ST segment depression leads was lower and the minimum voltage amplitude of ST segment depression was decreased compared with those before treatment in the two groups,the degree of change in the observation group being more significant than those in the control goup [angina attack frequency (times)5.2 ± 0.5 vs.9.4 ± 1.6,ST segment depression lead total number2.3-± 0.2 vs.4.6 ± 2.1,ST segment depression lowest voltage amplitude (my)0.10 ± 0.01 vs.0.31 ± 0.01,all P ＜ 0.05].The adverse effects incidence showed no statistical significant differences between control group and observation group [14.3％ (5/35) vs.22.8％ (8/35),P ＞ 0.05] Conclusions On the basis of conventional medication,Shexiang Baoxin pills combined with nicorandil has obvious therapeutic effect for treatment of microangiopathic angina pectoris.
