心肌急性缺血是冠心病发病学中公认的重要环节。急性心肌缺血的后果是否必然导致缺血心肌的全部坏死,近年来已有新的认识。1973年 Sobel 及 Shell 明确的把心肌梗塞后缺血心肌自中心向外周分为:中心坏死带、坏损的心肌(blighted myocardium)及濒危的心肌(jeopardized myocardium)三个区。并指出前二者是不可复的病变,而濒危心肌是可向坏死或恢复两个方向发展的。大量临床与实验材料说明,濒危心肌发展的方向与
Acute myocardial ischemia is an accepted and important link in the pathogenesis of coronary heart disease. Whether the consequences of acute myocardial ischemia will inevitably lead to the complete necrosis of ischemic myocardium has been a new understanding in recent years. In 1973, Sobel and Shell explicitly divided the ischemic myocardium after myocardial infarction into three regions: the central necrosis zone, the blighted myocardium and the jeopardized myocardium. And pointed out that the former two are irreversible lesions, while the endangered myocardium can be necrotic or recovery in both directions. A large number of clinical and experimental materials that the direction of the development of endangered myocardium
