心肌梗塞的发病因素,95％系冠状动脉粥样硬化,它所以对心脏产生不良影响,是因为病变部位的管腔狭窄或闭塞,使心脏的血液供应减少,甚至使冠状动脉急性闭塞所引起心脏缺血。由于缺血严重持久,使心肌发生不可逆转的组织上的损害而发生心肌梗死。冠状动脉闭塞多数会累及左冠状动脉的前降支,而较少发生于右冠状动脉与左冠状动脉回旋支。但近几年来根据有关资料统计报道,在中国人中右冠状动脉为主型的血管分布较西方人多,因而后壁心肌梗塞往往与后壁基底部心肌梗塞同时出现。笔者见一例急性广泛性后壁心肌梗塞(下壁、后壁、后侧壁)合并脑梗塞,特报道如下。
The incidence of myocardial infarction, 95% Department of coronary atherosclerosis, so it has a negative impact on the heart, because the stenosis of the lesion site or occlusion, so that the blood supply to reduce the heart, and even acute coronary artery occlusion caused by the heart Ischemia. Myocardial infarction occurs due to irreversible damage to the myocardium due to severe and prolonged ischemia. Most coronary occlusion involving the left anterior descending coronary artery, and less in the right coronary artery and left circumflex coronary artery. However, in recent years, according to the statistical data reported in the Chinese right coronary artery-based vascular distribution more than the West, so the posterior wall myocardial infarction and posterior wall basal myocardial infarction often occur at the same time. I see a case of acute extensive posterior myocardial infarction (inferior wall, posterior wall, posterior wall) with cerebral infarction, especially reported as follows.
