急性冠状动脉血栓形成的后果似乎十分简单,并没有什么使人真正感兴趣之处。动脉闭塞后,相应部位的心肌在数秒钟内发生缺血,几乎立即停止收缩。如缺血时间过长,心肌坏死。但冠状动脉闭塞后,其供血部位的心肌很少会全部死亡,实际上常常多少有相当部份的心肌能存活下来。所以,心肌梗塞往往是不完全的,梗塞区系由存活和坏死二部份心肌共同组成。对不完全性心肌梗塞的认识非常重要,这不仅因为在血供充分的条件下,梗塞区内的存活心肌有助于心脏功能的维持,而且因为在血供不稳定的情况下,不完全性梗塞灶又可成为日后再发生心肌缺血的部位。本文 The consequences of acute coronary thrombosis appear to be very simple and have no real point of interest. Artery occlusion, the corresponding part of the myocardial ischemia occurs in seconds, almost immediately stop contracting. Such as ischemia for a long time, myocardial necrosis. However, coronary artery occlusion, the blood supply to the site rarely all the death of the myocardium, in fact, often a considerable part of the myocardium can survive. Therefore, myocardial infarction is often incomplete, the infarct zone consists of two parts of the survival and necrosis of the myocardium together. Recognition of incomplete myocardial infarction is important not only because viable myocardium within the infarct area contributes to the maintenance of cardiac function under adequate blood supply, but also because of incompleteness in the case of unstable blood supply Infarction can become the site of myocardial ischemia in the future.
