目的 通过给予冠心病心绞痛气虚血瘀证患者芪参益气滴丸及西药治疗，探讨其疗效及对中医症状的影响。方法 将59例冠心病心绞痛气虚血瘀证患者随机分为西药组（29例）和西药＋中药组（30例）。西药治疗：参照美国心脏病学院/美国心脏学会/美国医师学院联合议定的冠心病心绞痛诊断及治疗指南；中药治疗：给予芪参益气滴丸0.5 g，tid，治疗60 d。观察治疗前后心绞痛疗效、硝酸甘油停减率及中医症状评分变化。结果 治疗后，西药＋中药组心绞痛总有效率及硝酸甘油停减率高于西药组，但2组比较无统计学意义（P＞0.05）；治疗后，2组胸痛、胸闷症状明显改善，2组与治疗前比较有显著差异性（P＜0.01）；西药组气短、乏力、心悸、自汗、面色少华症状无明显改善，与治疗前比较无差异性（P＞0.05）。西药＋中药组气短、乏力、心悸、自汗、面色少华症状明显改善，与治疗前比较有显著差异性（P＜0.01），西药＋中药组中医症状的改善优于西药组，且有显著差异性（P＜0.01）。结论 联合应用芪参益气滴丸及西药能有效地改善冠心病心绞痛气虚血瘀证患者的疗效及中医症状，值得临床推广。

Objective To investigate the effect of Qishen Yiqi Dripping Pills (QYDP) with western medicine on the deficiency of vital energy and blood stasis (DVEBS) of patients suffered from coronary heart disease (CHD)-caused angina pectoris. Methods Fifty-nine patients with DVEBS of CHD-caused angina pectoris were randomly divided into two groups, they are western medicine (WM, 29 patients) group and western + traditional Chinese medicines (WTCM, 30 patients) group. The therapy of WM group was in accordance with the guideline for diagnose and therapy of CHD-caused angina pectoris by American College of Cardiology (ACC)/American Heart Association (AHA)/American College of Physicians (ACP). The therapy of TCM was administration with 0.5 g QYDP once for three times daily and the treatment course was 60 d. The changes of curative effect on angina pectoris, stopping and decreasing rate of Nitroglycerin, and the score of TCM were observed. Results After 60 d treatment, the total effective rate and the stopping and decreasing rates of Nitroglycerin in WTCM group were higher than those in WM group, but there was no statistical significance (P>0.05). After the treatment, the symptoms of chest pain and dyspnea were significantly improved in both groups (P<0.01); The symptoms of short breath, acratia, cardiopalmus, spontaneous perspiration, and vultus were not significantly improved in WM group (P>0.05) but significantly improved in WTCM group (P<0.01). The symptoms in WTCM group were more significantly improved than those in WM group (P<0.01). Conclusion The therapeutic effect could be effectively improved by QYDP with western medicine in the patients with DVEBS of CHD-caused angina pectoris.
