摘要
目的：探讨低分子肝素联合小剂量阿司匹林治疗不稳定性心绞痛（UAP）的疗效。方法：采用随机分组，将52例不稳定性心绞痛患者分为两组。治疗组：低分子肝素（速避凝）0．4ml。皮下注射1次／天，连用7天，加服阿司匹林75mg／d。对照组：口服阿司匹林75mg／d。观察治疗前后不稳定性心绞痛发作频率及发作持续时间的变化。结果：低分子肝素联合小剂量阿司匹林治疗不稳定性心绞痛发作频率减少，发作持续时间缩短，与对照纽差异均有显著性（P〈0．01）。结论：低分子肝素联合小剂量阿司匹林治疗不稳定性心绞痛疗效显著。
Objective：Texamine the efficacy of low-molecular in combination withaspirin in treatment of postinfarction unsteady angina pectoris.Methods： fifty-tow postinfarction unsteady angina pectoris patients were randomly divided in tow group. Cure group： low-molecular heparin 0.4ml/d injected subcutaneously for seven days plus aspirin 75mg/d.Control group：aspirin75mg/dwas administered and the paroxysmal frequency,paroxysmal panes and side effects were observed before and after the drug therapy. Result：The frequency and duration of angina pectoris attacks in the cure group decreased significantly compared with those in the control group （p 〈 0.01） And few side effects were found. Conclusions：Low-molecular heparin in combination with aspirin are more effective than aspirin alone in the treatment of postinfarction unsteady angina pectoris.
