冠状动脉粥样硬化性心脏病,简称“冠心病”。冠心病会造成心肌缺血,出现心绞痛症状。但近年来临床实践已证明,发生心肌缺血时并不都发生心绞痛;而且不伴有心绞痛发作的,较伴随心绞痛发作的约多四倍。这种没有心绞痛发作的心肌缺血,称为“无症状性心肌缺血”。老年人最容易罹患 Coronary atherosclerotic heart disease, referred to as “coronary heart disease.” Coronary heart disease can cause myocardial ischemia, angina pectoris symptoms. However, in recent years, clinical practice has proved that the occurrence of myocardial ischemia does not occur when angina pectoris; and without angina pectoris than with angina pectoris about four times. This type of myocardial ischemia without angina pectoris is called “asymptomatic myocardial ischemia.” Older people are most at risk
