We performed exercise stress scintigraphy with thallium-201 in 88 patients including 31 patients of effort angina and nine patients of old myocardial infarction without angina. Sensitivity of exercise stress scintigraphy to detect effort angina was 77%, whereas sensitivity of exercise stress ECG was only 44.5%. The combination of stress scintigraphy with stress ECG enhanced sensitivity up to 87%. Exercise stress scintigraphy was useful particularly in cases with one vessel disease and those who failed to achieve sufficient exercise stress. Besides exercise stress scintigraphy did not show false positive response, differing from exercise stress ECG. Myocardial imaging is a method which shows the balance between myocardial perfusion demand and supply.
我们对88例患者进行了铊-201运动应激闪烁扫描，其中包括31例劳力型心绞痛患者和9例无心绞痛的陈旧性心肌梗死患者。运动应激闪烁扫描检测劳力型心绞痛的敏感性为77%，而运动应激心电图的敏感性仅为44.5%。应激闪烁扫描与应激心电图相结合可将敏感性提高至87%。运动应激闪烁扫描在单支血管病变及未能达到足够运动应激的患者中尤为有用。此外，与运动应激心电图不同，运动应激闪烁扫描未显示假阳性反应。心肌显像是一种显示心肌灌注需求与供应之间平衡的方法。
