自1980年8月起,我院对心肌梗塞急性期进行了冠状动脉内血栓溶解疗法,1983年5月起尿激酶量增加一倍。冠状动脉内给药时间从20分钟延长到60分钟,即使是经静脉给药,血栓溶解率分别为76％和73％。和许多报告大致相同。 本文就心肌梗塞急性期的冠状动脉造影所见,对血栓溶解率,心功能,死亡率等是否有年龄差异关系,对65岁以上(A组),64～55岁 Since August 1980, our hospital for acute myocardial infarction in coronary thrombolytic therapy, in May 1983 since the amount of urokinase doubled. The duration of coronary administration was extended from 20 minutes to 60 minutes and the rates of thrombolysis were 76% and 73%, respectively, even after intravenous administration. And many reports about the same. In this paper, myocardial infarction acute coronary angiography seen, the thrombolytic rate, cardiac function, mortality and other whether there are age differences between the age of 65 (A group), 64 to 55 years old
