由于监测方法的进步,近年来对冠心病有了更深入的认识,认识到无痛性和无症状性冠心病的普遍性和重要性,它是引起心肌梗塞的(MI)和心源性猝死(SCD)的重要原因。其预后与有痛的和有症状的冠心病一样甚至更差。还认识到用疼痛来诊断和判断疗效很不全面。有症状的心绞痛,在整个冠心病中只是冰山的一个尖,在其下边还有更广阔的范围。关于无症状性心肌缺血,国内最近已有报告。名称:早在1912年就认识到无症状(Silent)MI,MI 有的疼痛不典型或表现为其他症状。现多称此为“无痛性MI”。心肌缺血发作也可无痛,或疼痛不典型或表现为其他症状。无痛性心肌缺血发作也常见于有典型心绞痛和MI 者。还可表现为心肌病、心功不全和猝死。上述各种情况并非完全无症状,而其共同的特点是无痛,所以称为“无痛性冠
Due to the progress of monitoring methods, coronary heart disease in recent years have a more in-depth understanding of the painless and asymptomatic coronary heart disease to recognize the universality and importance of it is caused by myocardial infarction (MI) and sudden cardiac death (SCD) of the important reasons. Its prognosis is as worse or even worse as the painful and symptomatic coronary heart disease. Also recognize that the pain to diagnose and determine the efficacy is not comprehensive. Symptomatic angina is just a tip of the iceberg throughout the coronary heart disease, with a much wider area below it. Asymptomatic myocardial ischemia, the domestic has recently been reported. Name: As early as 1912 to recognize asymptomatic (Silent) MI, MI some of the pain is not typical or manifested as other symptoms. Now called the “painless MI.” Myocardial ischemic attacks can also be painless, or atypical pain or other symptoms. Painless myocardial ischemia is also common in patients with typical angina and MI. Can also be manifested as cardiomyopathy, cardiac insufficiency and sudden death. The above conditions are not completely asymptomatic, and their common feature is painless, so called "painless crown
