最近的病生理研究把急性心肌梗塞(AMI)看做一个进展性的过程,此过程分为三个阶段:1.初期——即从冠脉闭塞、心肌缺血到坏死的初始阶段,持续时间大致在12小时内。在这一期间,心肌的损伤在某种程度上是可逆的。2.中期——即心梗后第一周,此期出现心肌梗塞的各种并发症。3.梗后第一年——某些病人仍处于再梗塞和心律失常的危险中。这一新概念的提出有重要的临床意义,目前急性心梗的治疗研究重点则集中在心梗的进
Recent pathophysiological studies of acute myocardial infarction (AMI) as a progressive process, the process is divided into three stages: 1. Initial - that is, from coronary artery occlusion, myocardial ischemia to the initial stage of necrosis, duration Roughly in 12 hours. During this period, myocardial damage is somewhat reversible. 2. Mid - that is the first week after myocardial infarction, myocardial infarction during this period of complications. 3. First year after stem - Some patients are still at risk of reinfarction and arrhythmia. The proposed new concept has important clinical significance, the current focus of research on the treatment of acute myocardial infarction is focused on myocardial infarction
