目的探讨曲美他嗪联合稳心颗粒治疗不稳定性心绞痛的效果。方法将我院2009年12月-2012年12月86例不稳定性心绞痛患者随机分为两组各43例，A组给予常规治疗，B组加用曲美他嗪联合稳心颗粒，比较两组临床疗效和安全性。结果治疗14d后，B组临床疗效明显优于A组，差异有统计学意义(P<0.05)，两组不良反应发生率无统计学差异。结论曲美他嗪联合稳心颗粒能明显改善不稳定性心绞痛临床疗效，安全可靠，不良反应少。%Objective To investigate the clinical efficacy and safety of unstable angina patients by trimetazidine and metacentric particles. Methods Eighty-six unstable angina patients who were treated in general internal medicine of our hospital from December 2009 to December 2012 were chosen as the research objects,then patients were divided into group A(n=43) and group B(n=43) by using a random number table,patients in group A was given conventional treatment, patients in group B was given trimetazidine and metacentric particles on the basis of group A, the clinical efficacy and safety of two groups was evaluated. Results After fourteen days, the total efficient rate was higher in group B than that in group A(P<0.05), and there were no significant differences between the two groups. Conclusion The efficacy of unstable angina patients by trimetazidine and metacentric particles is affirmative, it is safe and reliable.
