Stress T1-201 myocardial scintigraphy was carried out in 16 patients with x-syndrome. Eleven patients having IHD with single-vessel disease served as the control. With bicycle exercise test all 16 patients with x-syndrome had some type of myocardial perfusion abnormality. These perfusion defects were situated in the vascular beds of different coronary arteries. Myocardial perfusion defects in patients with x-syndrome were similar to those patients with moderate, but haemodynamically significant, single-vessel disease. At the same time, these perfusion defects were significantly less pronounced than those in patients with a subtotal occlusion of one coronary artery. Thus, patients with x-syndrome have not only the clinical features of IHD (anginal attacks), but also marked stress-induced, myocardial perfusion defects.
对16例X综合征患者进行了应激T1-201心肌闪烁显像检查。选取11例患有单支血管病变的缺血性心脏病（IHD）患者作为对照。通过自行车运动试验，所有16例X综合征患者均出现某种类型的心肌灌注异常。这些灌注缺损位于不同冠状动脉的血管床。X综合征患者的心肌灌注缺损与患有中度但血流动力学显著的单支血管病变的患者相似。同时，这些灌注缺损比冠状动脉次全闭塞患者的缺损明显不那么显著。因此，X综合征患者不仅具有缺血性心脏病的临床特征（心绞痛发作），还具有明显的应激诱导性心肌灌注缺损。
