Using exercise stress thallium (Tl)-201 SPECT, we studied 11 patients with Syndrome X who had anginal pain and ischemic ECG change during exercise in spite of angiographically normal coronary artery. In three patients, the initial stress image showed mild hypoperfusion in the area of ST segment depression, but the delayed image showed complete or incomplete redistribution. Eight cases showed normal perfusion. This result suggests that some patients of Syndrome X could be caused by small vessel disease.
我们使用运动负荷铊（Tl）-201单光子发射计算机断层扫描（SPECT）对11例X综合征患者进行了研究，这些患者尽管冠状动脉造影正常，但在运动时仍有胸痛和缺血性心电图改变。3例患者初始负荷图像显示ST段压低区域有轻度灌注减低，但延迟图像显示有完全或不完全再分布。8例显示灌注正常。这一结果提示，部分X综合征患者可能由小血管疾病引起。
