无症状心肌缺血是指解剖上有明显冠状动脉病变的患者虽无临床症状但有心肌缺血的客观证据.Cohn氏将无症状心肌缺血分为三种型:Ⅰ型;即无冠心病的症状,也无冠心病史,但存在无症状心肌缺血;Ⅱ型:既往有心肌梗塞,现存在无症状心肌缺血;Ⅲ型;有心绞痛,也有无症状心肌缺血发作.在出现一过性心肌缺血时,无症状性与有症状性的一样先有心脏舒张及收缩功能异常,随后出现心电图ST段缺血型改变.无
Asymptomatic myocardial ischemia refers to the objective evidence of myocardial ischemia, although there is no clinical symptoms in patients with anatomically significant coronary lesions.Cohn’s will be divided into three types of asymptomatic myocardial ischemia: type I; that is, no coronary heart disease Of the symptoms, there is no history of coronary heart disease, but the presence of asymptomatic myocardial ischemia; type II: previous myocardial infarction, there is no ischemic myocardium; type Ⅲ; angina, there are asymptomatic myocardial ischemic attack. Myocardial ischemia, asymptomatic asymptomatic systolic and diastolic dysfunction, followed by ischemic ST segment ischemic changes.
