临床研究表明,90%以上的急性ST段抬高型心肌梗死是由冠状动脉血栓形成所致,故溶栓是使闭塞的冠脉血管再通、恢复心肌再灌注及限制心肌坏死范围扩大最有效的方法之一;是临床上治疗急性ST段抬高型心肌梗死的主要手段,尤其在无条件开展心血管介入治疗的基层医院其显得更为重要。本 Clinical studies have shown that more than 90% of acute ST-elevation myocardial infarction is caused by coronary thrombosis, so thrombolysis is the most effective in recanalizing revascularized coronary artery, restoring myocardial reperfusion and limiting the extent of myocardial necrosis ; It is one of the main methods to treat acute ST-segment elevation myocardial infarction clinically, which is more important especially in the grass-roots hospitals who have unconditional cardiovascular intervention. this
