作者研究了27例主诉胸痛而冠状动脉造影显示无明显阻塞性病变(冠状动脉直径狭窄小于50%)的病人,其中15例有典型心绞痛,12例为非典型心绞痛。所有病人均作最大运动量的踏车心电图运动试验。在接近最大运动量时,静脉注射~(201)铊1.5mcj,继续运动1～2分钟。停止运动后8～12分钟,记录运动~(201)铊灌注显影。运动后4小时记录休息~(201)铊灌注显
The authors studied 27 patients who complained of chest pain and coronary artery angiography showed no significant obstructive lesions (coronary stenosis less than 50%), of which 15 had typical angina and 12 had atypical angina. All patients were maximum exercise treadmill ECG exercise test. Near the maximum amount of exercise, the intravenous injection of ~ (201) thallium 1.5mcj, continued exercise for 1 to 2 minutes. 8 to 12 minutes after stopping the exercise, recorded exercise ~ (201) thallium perfusion imaging. Rest 4 hours after exercise recorded ~ (201) Thallium perfusion significantly
