目的观察低分子肝素治疗心绞痛的疗效。方法选择符合心绞痛患者80例,随机分为治疗组A42例(低分子肝素组+常规药物治疗),和对照组B38例(未使用低分子肝素组),比较两组治疗心绞痛的疗效。结果治疗组有效率95.2%,对照组有效率65.79%,两组存在显著差异。结论低分子肝素联合常规治疗药物对心绞痛患者是安全有效的治疗方法。 Objective To observe the curative effect of low molecular weight heparin on angina pectoris. Methods A total of 80 patients with angina pectoris were selected and randomly divided into treatment group A42 (low molecular weight heparin group + conventional drug treatment) and control group B38 (low molecular weight heparin group). The curative effect of angina pectoris in both groups was compared. Results The effective rate was 95.2% in the treatment group and 65.79% in the control group, with significant differences between the two groups. Conclusion Low molecular weight heparin combined with conventional treatment of patients with angina is safe and effective treatment.
