Objective: to analyze simvastatin combined low molecular heparin for treatment of unstable angina, and provide reference for clinical treatment of unstable angina. Methods: randomly selected from our hospital in August 2011 to August 2013 were analyzed in 84 cases of patients with unstable angina, 42 cases of patients were divided into observation group and control group, 42 cases, Control group using aspirin + as those of nitrate medications, observation group in the control group of drug use, on the basis of using simvastatin combined therapy with low molecular heparin, contrast observe the therapeutic effect of two groups of patients. Results: 18 cases were markedly effective, observing group, 19 cases effectively, invalid in 5 cases, total effective rate 88.1%; Control group 14 cases were markedly effective, effective in 16 cases, 12 cases, total effective rate 71.4%. Observation group treatment effect is bet er than the control group, compared the two groups have dif erence (P< 0.05). Conclusion: simvastatin combined low molecular heparin in the treatment of unstable angina, treatment effect is good, safe and effective, worthy of clinical promotion.%目的：分析辛伐他汀联合低分子肝素治疗不稳定型心绞痛的临床效果，为不稳定型心绞痛的临床治疗提供参考。方法随机选取我院2011年8月~2013年8月收治的84例不稳定型心绞痛患者，将患者分为观察组42例与对照组42例，对照组采用阿司匹林+硝酸酯类药物治疗，观察组在对照组的用药基础上，采用辛伐他汀联合低分子肝素治疗，观察对比两组患者的治疗效果。结果观察组显效18例，有效19例，无效5例，治疗总有效率88.1%；对照组显效14例，有效16例，无效12例，治疗总有效率71.4%。观察组治疗效果明显优于对照组，两组对比有差距（P＜0.05）。结论辛伐他汀联合低分子肝素治疗不稳定型心绞痛，治疗效果良好，安全有效，值得临床推广。
