急性心肌梗塞的溶血栓疗法,能有效地限制心肌梗塞面积,改善心肌梗塞的病程。本文就其有关问题做一概述。一、溶血栓疗法的机理近十余年来,通过临床和实验研究证明,心肌梗塞是在数小时內发生病理演变的动态过程,若在此期间及早采取措施将会减少心肌坏死的程度。缩小梗塞面积的措施主要是降低氧需和增加氧供。现已明确,心肌梗塞与冠状动脉内的血栓形成有关,但由于不 Thrombolytic therapy of acute myocardial infarction can effectively limit the area of ​​myocardial infarction and improve the course of myocardial infarction. This article gives an overview of its related issues. First, the mechanism of thrombolytic therapy over the past decade, through clinical and experimental studies have shown that myocardial infarction is a dynamic process of pathological evolution within a few hours, if taken during this period early measures will reduce the extent of myocardial necrosis. The main measures to reduce infarct size are to reduce oxygen demand and increase oxygen supply. It is clear that myocardial infarction and coronary thrombosis related, but not because
