肝素问世已近80年了,而其临床价值并没有降低。但普通肝素生物利用度低,临床应用须监测凝血活酶时间。目前,人们开始重视低分子肝素的研究。我们于1998年1月至1999年2月,将临床上诊断为不稳定型心绞痛28例为治疗组,设对照组为26例,对比分析了低分子肝素治疗不稳定型心绞痛的临 Heparin has been around for nearly 80 years, but its clinical value has not decreased. However, unfractionated heparin bioavailability is low, clinical application to monitor thromboplastin time. At present, people began to attach importance to the study of low molecular weight heparin. We in January 1998 to February 1999, the clinical diagnosis of unstable angina in 28 cases for the treatment group, the control group was 26 cases, comparative analysis of low molecular weight heparin for the treatment of unstable angina
