本文报告心肌灌注断层显像(SPECT)231例,并与ECG结果作了对比分析。结果表明:心肌SPECT对缺血性心脏病的阳性检出率明显高于ECG(P<0.05)ECG与SPECT阳性结果的吻合率仅为72.1％,而ECG无缺血(IS)和梗塞(MI)的患者中,40.8％SPECT有阳性发现。SPECT的定位诊断率明显优于ECG(P<0.01),尤其对心尖、侧壁和后壁基底段更显示出SPECT的优势。因此作者认为,SPECT作为一种具有较高灵敏度而又无创伤的检测手段,应作为缺血性心脏病的首选检查方法。
This article reports myocardial perfusion tomography (SPECT) 231 cases, and ECG results were analyzed. The results showed that the positive rate of myocardial SPECT to ischemic heart disease was significantly higher than that of ECG (P <0.05). The coincidence of ECG and SPECT positive results was only 72.1%, while ECG was not ischemic (IS) and infarct ) Of the patients, 40.8% SPECT positive findings. The diagnostic accuracy of SPECT was significantly better than that of ECG (P <0.01), especially for apical, lateral and posterior basal segments. Therefore, the authors believe that, SPECT as a highly sensitive and non-invasive detection means should be used as the first choice of ischemic heart disease test.
