摘　　要：目的探讨冠心病患者无症状心肌缺血阈的临床特点及其发生规律。方法应用24h动态心电图监测68例冠心病患者的心肌缺血阈及其变异度。结果共检出无症状性心肌缺血403次,有症状心肌缺血46次,前者的发生率明显高于后者。结论心肌缺血是冠心病最常见的表现形式,因心肌缺血发生机制不同,应根据发病情况给予不同的治疗、是冠心病最常见的表现形式,因心肌缺血发生机制不同,应根据发病情情况给予不同的治疗。Objective To evaluate the clinical characteristics and occurrence rules of silent myocardial ischemia （SMI） in patients with coronary artery disease. Methods Sixty - eight patients with coronary artery disease were investigated by 24 -hour ambulatory electrocardiogram, to observe myocardial ischemic threshold and variability of cardial ischemic threshold. Results Myocardial ischemia was found to occur 403 times, and symptomatic ischemia was 46 times,the incidence rate of the former was higher than the latter. Conclusion SMI is the most common manifestation in patients with coronary artery disease. There are different kinds of mechanism in myocardial ischemia. It is necessary for us to use different methods in treatment.
