Methods： The prospective, non-randomized controlled study was conducted on 51 selected patients with CSX, who were non-randomly assigned to 2 groups, the treated group treated with LKH in addition to the conventional treatment （32 patients）, and the control group treated with conventional treatment （19 patients） like nitrate, diltiazem hydrochloride, etc. The treatment course was 14 days. The changes of such symptoms as angina pectoris, TCM syndrome and indexes of treadmill exercise test before and after treatment were observed. Results： After treatment, such symptoms as chest pain and stuffy feeling and palpitation in the treated group were improved more than those in the control group （P〈0.05）; the total effective rate on angina pectoris and TCM syndrome in the treated group was better than that in the control group （P〈0.05）. The treadmill exercise test showed that the maximal metabolic equivalent （Max MET）, the time of angina onset and ST segment depression by 0.1 mV were obviously improved after treatment in both groups, but the improvement in the treated group was better than that in the control group respectively （P〈0.05）. Conclusion： The LKH method could reduce the frequency of angina attacks and improve the clinical condition of patients with CSX.展开更多
