小剂量尿激酶治疗非ST段抬高急性冠脉综合征76例临床观察

目的:观察小剂量尿激酶溶栓治疗非ST段抬高急性冠脉综合征(NSTE-ACS)的疗效和安全性。方法:选择NSTE-ACS患者76例(男43例,女34例),随机分为溶栓组和对照组。治疗组应用尿激酶30万U/d,共7～10d,对照组未使用尿激酶,其他治疗方法与溶栓组完全一致。观察两组患者治疗前后心绞痛发作频率、心电图变化、出血并发症及心血管意外等情况,同时监测血小板计数(Plt)、凝血酶原时间(PT)、激活的部分凝血活酶时间(APTT)、纤维蛋白原(FIB)。结果:1溶栓组患者总有效率及显效率明显高于对照组,两组出血并发症发生率无显著性差异;对照组有1例发生急性心肌梗死,溶栓组未出现急性心脏事件。2溶栓组FIB在治疗后明显下降(P<0.01),对照组FIB无明显变化,溶栓前后Plt、PT、APTT无明显变化。结论:1NSTE-ACS患者进行小剂量尿激酶溶栓治疗可以改善临床症状,且不增加出血并发症和心脏恶性事件发生率。2在应用低分子肝素的基础上,使用小剂量尿激酶溶栓治疗未发生凝血功能异常,且出现纤溶亢进,提示小剂量溶栓治疗是安全的。

Clinical effect observation in patients with non-ST-segment elevation acute coronary syndrome after thrombolytic therapy by low dose urokinase

Objective:To observe clinical curative effect and security in certain subgroup patients with non-ST-segment elevation acute coronary syndrome after thrombolytic therapy by low dose urokinase.Methodes:76 patients(male 43 and female 34)with non-ST-segment elevation acute coronary syndrome were chosen and subdivided randomly into thrombolytic therapy group and control group.Except the injection of urokinase,the same procedure was done in the two groups.Before and after the therapy,angina recurrence rates,ECG c...
