为了评价急性心肌梗塞(AMI)早期静注β阻滞剂的安全性和效益,作者对AMI连续131例,从起病开始6小时内用溶栓剂者,给予静注β阻滞剂。患者年龄均<75岁,静注β阻滞剂,需排除以下反指征:有哮喘或支气管痉挛;有明显传导障碍;低血压(收缩压<12kPa),有临床左心衰等。方法:全部患者口服阿司匹林150mg与用一种溶栓剂(如链激酶、尿激酶、重组组织型纤溶酶原激活剂等),待溶栓剂输注完毕后约15分钟,静注美多心安15mg或氨酰心胺5mg,5分钟注入,注射时严密观察生命体征,3小时后口服氨酰心胺50mg,每
To assess the safety and benefit of early beta-blockers in patients with acute myocardial infarction (AMI), we assigned consecutive beta-blockers to AMI in 131 consecutive patients who received thrombolytics within 6 hours of onset. Patients aged <75 years, intravenous beta blockers, the following anti-indications to be ruled out: There are asthma or bronchospasm; significant conduction disorders; hypotension (systolic blood pressure <12kPa), clinical left heart failure and so on. Methods: All patients received oral aspirin 150mg with a thrombolytic agent (such as streptokinase, urokinase, recombinant tissue-type plasminogen activator, etc.) to be about 15 minutes after the completion of infusion of thrombolytic agents, intravenous injection of the United States and more Cardiac 15mg or ammonia amide 5mg, 5 minutes into the injection, close observation of vital signs, 3 hours after the oral aminoacyl amine 50mg, each
