阿纳海姆消息:流过心肌的血流不是均匀不变的。当研究人员逐渐了解心肌血流的分布情况时,对心肌缺血的概念也随之而变化。洛杉矶的H J C Swan在美国心脏病学学院召开的会议上谈到关于急性心肌缺血病人的分类对,指出,有证据表明,在有严重冠状动脉狭窄的情况下,心外膜从心内膜中“窃取”血液。这种透壁性窃取现象目前被认为是多数急性心肌缺血综合征的非常重要的部分。在各种临床表现中,Swan提出以下特点: Heberden氏心绞痛是慢性的,实际上是很少发生的稳定型心绞痛。这种类型的心绞痛 Anaheim News: The flow of blood through the myocardium is not uniform. As researchers gradually understand the distribution of myocardial blood flow, the concept of myocardial ischemia also changes. HJC Swan of Los Angeles spoke at a meeting of the American College of Cardiology at a conference on the classification of patients with acute myocardial ischemia, pointing out that there is evidence that in the presence of severe coronary artery stenosis, the epicardium is removed from the endocardium “Steal” the blood. This transmural steal is now considered to be a very important part of most acute myocardial ischemia syndromes. In a variety of clinical manifestations, Swan proposed the following features: Heberden’s angina is chronic and is actually a rare form of stable angina. This type of angina
