ECG gated 201Tl scintigraphy was compared to non gated images for detecting 2-3 vessel disease 1-3 months after a first uncomplicated myocardial infarction. In all, 111 patients on anti anginal treatment underwent coronary arteriography and stress thallium imaging; 39 showed single vessel disease (SVD), and 72 multivessel disease (MVD). Sensitivity of black and white analog images was 82% for SVD and 8% for MVD. Sensitivity of computerized colored static images was 87% for SVD and 33% for MVD. For gated images, sensitivity was 100% and 92% in patients with SVD and MVD respectively. Specificity for detecting MVD was 95% for black and white images, 77% for computerized colored static images, and 69% for ECG gated images. Thus, ECG gated exercise 201TL scintigraphy is useful for predicting the extent of coronary artery disease 1-3 months after myocardial infarction in patients on anti anginal therapy.
在首次无并发症心肌梗死后1至3个月，将心电图门控201铊闪烁扫描与非门控图像进行比较，以检测双支或三支血管病变。共有111例接受抗心绞痛治疗的患者接受了冠状动脉造影和负荷铊显像；39例显示单支血管病变（SVD），72例显示多支血管病变（MVD）。黑白模拟图像对SVD的敏感性为82%，对MVD的敏感性为8%。计算机彩色静态图像对SVD的敏感性为87%，对MVD的敏感性为33%。对于门控图像，SVD和MVD患者的敏感性分别为100%和92%。检测MVD的黑白图像特异性为95%，计算机彩色静态图像为77%，心电图门控图像为69%。因此，心电图门控运动201铊闪烁扫描有助于预测抗心绞痛治疗患者心肌梗死后1至3个月冠状动脉疾病的程度。
