摘要
目的:评价24小时动态心电图和核素心肌断层显像检查对非典型心绞痛冠心病的诊断效果.方法:回顾性分析33例非典型心绞痛病人,均行动态心电图和核素心肌断层显像检查,结果与冠状动脉造影比较.结果:动态心电图诊断非典型心绞痛冠心病心肌缺血敏感性37.5%,特异性36%.核素心肌断层显像检查诊断非典型心绞痛冠心病心肌缺血敏感性87.5%,特异性24%.结论:对临床上以非典型心绞痛为主诉的病人,临床医生根据24小时动态心电图和核素心肌断层显像检查结果诊断冠心病应慎重,必要时选用冠状动脉造影检查.
Objective: To evaluate the value of a 24 hours Holter monitor and thallium-201 single-photon emission computed tomography for the diagnosis of myocardial ischemia in patients with atypical angina. Methods: The clinical data of 33 patients with atypical angina undergoing Holter monitor and thallium-201 single-photon emission computed tomography were analysed. All of the patients had coronary angiography. The results of them were compared. Results: The sensitivity and specificity of Holter for coronary heart disease detection were 37.5% and 36%. The sensitivity and specificity of thallium-201 single-photon emission computed tomography for coronary heart disease detection were 87.5% and 24%. Conclusions: Physicians should be cautious to make a diagnosis of coronary heart disease in patients with atypical angina, according to the results of Holter and thallium-201 single-photon emission computed tomography. Coronary angiography should be done if in necessary.
