目的低分子肝素钠治疗不稳定型心绞痛的疗效和安全性。方法将198例患者随机分为两组各99例,A组应用阿司匹林和抗心绞痛药物常规治疗,同时每12小时皮下注射低分子肝素钠5000U,连用7d。B组给予阿司匹林和抗心绞痛药物常规治疗。结果心绞痛症状缓解有效率A组为95.1%,B组为81%,心电图总有效率分别为95.9%及71.7%,两组相比差异有统计学意义(P<0.05)。A组低分子肝素治疗全部耐受,无一例出血。结论低分子肝素钠治疗不稳定型心绞痛可有效缓解心绞痛。
Objective To evaluate the efficacy and safety of low molecular weight heparin in the treatment of unstable angina pectoris. Methods 198 patients were randomly divided into two groups of 99 cases. Group A was treated with aspirin and anti-anginal drugs routinely. At the same time, low-molecular-weight heparin 5000U was injected subcutaneously every 12 hours for 7 days. B group given aspirin and anti-anginal drugs conventional treatment. Results The effective rate of relieving angina pectoris was 95.1% in group A, 81% in group B, and 95.9% and 71.7% in total respectively. There was significant difference between the two groups (P <0.05). A group of low molecular weight heparin treatment of all tolerance, without a case of bleeding. Conclusion Low molecular weight heparin sodium for the treatment of unstable angina pectoris can effectively relieve angina pectoris.
