前言急性心肌梗塞的治疗,自60年代成功地取得心肺复苏,直流电颤这两大里程碑性质的进展,并建立了CCU,使住院病死率从30～40％下降到了15％左右。以后虽然应用了Gwan——Ganz漂浮导管进行血液动力学监测,纠正急性心肌梗塞所引起的血液动力学紊乱,然而,急性心肌梗塞的病死率却一直徘徊在15％左右。造成这部分死亡的原因多不是致命的心律失常,而是梗塞面积过大所引起的泵衰竭,尤其是心源性休克病死率高达80％～90％。因此,近十余年来的研究着重是如何缩小梗塞范围及重建冠脉循环。因此冠状动脉腔内成形术(PTCA)及冠状动脉内血栓溶解疗法引起了普遍的兴趣和关注。
Preface The treatment of acute myocardial infarction has been successful in the two landmark milestones of cardiopulmonary resuscitation and defibrillation since the 1960s. CCU has been established to reduce the in-hospital mortality rate from 30-40% to about 15%. Although Gwan - Ganz floating catheter was used for hemodynamic monitoring to correct the hemodynamic disturbance caused by acute myocardial infarction, the mortality rate of acute myocardial infarction has been hovering around 15%. This part of the cause of death caused by more than fatal arrhythmia, but the infarct caused by excessive pump failure, especially in cardiogenic shock as high as 80% to 90%. Therefore, more than ten years of research focused on how to reduce infarct size and reconstruction of coronary circulation. Therefore, coronary artery endoloplasty (PTCA) and coronary thrombolysis have caused widespread interest and attention.
