本文以冠状动脉造影作为诊断冠心病的标准,对临床确诊为冠心病的患者进行运动心电图、运动~(201)铊心肌显像和动态心电图检查。结果证明:这三种方法诊断冠心病心肌缺血的敏感性在心绞痛组分别为85.9%、88.7%和58.4%,心肌梗塞组分别为77.2%、91.1%和53.4%,特异性分别为77%、90%和73%。检查中无症状心肌缺血发生率在心绞痛组分别为52.9%、56.3%和58.4%,心肌梗塞组分别为58.7%、75.3%和53.4%。表明这三种方法对诊断冠心病无症状心肌缺血有较高价值。
In this paper, coronary angiography as a diagnostic standard of coronary heart disease, clinical diagnosis of coronary heart disease in patients with exercise ECG, exercise ~ (201) thallium myocardial imaging and dynamic electrocardiogram. The results showed that the sensitivity of these three methods to diagnose myocardial ischemia in patients with coronary heart disease were 85.9%, 88.7% and 58.4% in the angina pectoris group, 77.2%, 91.1% and 53.4% in the myocardial infarction group, and the specificity was 77% , 90% and 73%. The incidence of asymptomatic myocardial ischemia was 52.9%, 56.3% and 58.4% in the angina pectoris group and 58.7%, 75.3% and 53.4% in the myocardial infarction group respectively. Show that these three methods for the diagnosis of coronary heart disease asymptomatic myocardial ischemia have higher value.
