Stress thallium scintigraphy was performed in 60 patients with chest pain of uncertain origin. Myocardial ischemia was identified in 91% of the 47 patients who had angiographically significant coronary artery stenoses. Sensitivity of thallium scintigraphy was highest in patients with stenosis in the left descending coronary artery (LAD); 91% of the patients had abnormal thallium as compared with 67% of the patients with normal LAD but significant stenoses in the circumflex artery and/or the right coronary artery. Perfusion defects in the circumflex in only 50% of the patients with multiple vessel disease. We conclude that stress thallium scintigraphy is a useful diagnostic procedure in patients with chest pain of uncertain origin and identifies the patients to be selected for coronary artery angiography.
对60例病因不明的胸痛患者进行了负荷铊闪烁扫描。在47例经血管造影证实有明显冠状动脉狭窄的患者中，91%发现有心肌缺血。铊闪烁扫描在左冠状动脉前降支（LAD）狭窄的患者中敏感性最高；91%的此类患者铊扫描异常，而LAD正常但回旋支和/或右冠状动脉有明显狭窄的患者中这一比例为67%。多支血管病变患者中仅50%的患者回旋支有灌注缺损。我们得出结论，负荷铊闪烁扫描对于病因不明的胸痛患者是一种有用的诊断方法，可确定哪些患者需要进行冠状动脉造影。
