目前大量研究资料表明:急性心肌梗死早期溶栓治疗,可缩小梗死面积及改善预后。据文献报道,3小时内尿激酶静脉溶栓,冠状动脉再通率为53%,而3～6小时之间仅为37%,这被称为溶栓治疗中的时间依赖性[1]。可谓“时间就是心肌细胞。”ＭＩＴＩ研究也表明,如于发病后70ｍｉｎ内溶栓,30? At present a large number of research data show that: early thrombolytic therapy of acute myocardial infarction, can reduce infarct size and improve prognosis. It has been reported in the literature that intravenous thrombolysis with urokinase within 3 hours resulted in a 53% rate of coronary recanalization, compared to 37% between 3 and 6 hours, which is called time-dependent thrombolysis [1]. Time is cardiomyocytes. "The MITI study also showed that, for example, thrombolysis within 70 min of onset,
