心肌梗塞病人直接冠状动脉内政静脉内注入溶栓剂如链激酶,使闭塞的冠状动肮再灌注,从而改善了左室功能和近期生存率。这两种方法获得效果基本相同,而静脉内给药却更实用方便。作者将403例疑为心肌梗塞病人列为研究对象,适于静脉内溶栓治疗的入选标准是:1、疑为心肌梗塞的胸痛;2、症状发作后6小时内入院;3、入院时和症状发作后至少30分钟,心电图标准导联ST段抬高1mm或心前导联抬高2mm。排除的标准是:1、脑血管病;2、消化性溃疡史或有出血倾向的其它疾病史;3、入院时血压>180/110 mmHg;4、4周前曾作手术治疗;5、心肺复苏术或治疗开始前中央血管插管术;6、以前曾列入 Thrombolytic agents, such as streptokinase, are injected directly into the internal coronary arteries of patients with myocardial infarction to improve the left ventricular function and recent survival by occluding coronary reperfusion. These two methods are basically the same effect, but intravenous administration is more practical and convenient. The authors enrolled 403 patients with suspected myocardial infarction as study subjects and was eligible for intravenous thrombolysis as the inclusion criteria: 1, chest pain suspected of myocardial infarction, 2, admission within 6 hours after the onset of symptoms, 3, At least 30 minutes after the onset of symptoms, the ST segment elevation of the standard lead in the ECG is 1 mm or the elevation of the precordial lead is 2 mm. Exclusion criteria were: 1, cerebrovascular disease; 2, history of peptic ulcer or other disease with bleeding tendency; 3, blood pressure at admission> 180/110 mmHg; 4, 4 weeks prior to surgery; 5, cardiopulmonary Central vascular intubation prior to resuscitation or treatment; 6, previously included
