心肌梗塞是冠状动脉闭塞,血流中断,心肌严重而持久的缺血以致于坏死所引起的一种临床综合征。按病变发展,在发病后的8周内称为急性心肌梗塞。此时,由于心肌受到严重损伤,心肌的电活动和机械活动均处于不稳定状态,所以病情容易发生突变,甚至发生猝死。在所有急性心肌梗塞的患者中:约1/2～2/3死于住院前的短时间内。因此,我们应加强对本病的认识,并在急救箱内常备必需的药品,发现病人时宜就地抢救。
Myocardial infarction is a clinical syndrome caused by coronary artery occlusion, interrupted blood flow, and severe and persistent myocardial ischemia resulting in necrosis. According to the development of lesions, 8 weeks after the onset of acute myocardial infarction. At this point, due to severe myocardial damage, myocardial electrical activity and mechanical activity are in an unstable state, so the disease prone to mutation, or even sudden death. In all acute MI patients: Approximately one-half to two-thirds die shortly before hospitalization. Therefore, we should strengthen our understanding of this disease and keep the necessary medicines in the first-aid kit.
