The authors reviewed the stress Tc-99m MIBI SPECT results and clinical data of 15 patients with syndrome X. The results of exercise EKG and resting left ventricular ejection fraction (LVEF) were compared with the results of Tc-99m MIBI SPECT. Of the 15 patients, 9 (60%) had a normal Tc-99m MIBI SPECT study and 6 (40%) had an abnormal Tc-99m MIBI SPECT. The authors found that 1) an abnormal Tc-99m MIBI SPECT was common in syndrome X, 2) the results of the exercise EKG were not related to perfusion defects on Tc-99m MIBI SPECT, and 3) for patients with an abnormal Tc-99m MIBI SPECT, the incidence of an abnormal resting LVEF and cardiac abnormalities were not higher than in patients with normal Tc-99m MIBI SPECT studies.
作者回顾了15例X综合征患者的负荷锝-99m甲氧基异丁基异腈单光子发射计算机断层显像（Tc-99m MIBI SPECT）结果及临床资料。将运动心电图结果和静息左心室射血分数（LVEF）与Tc-99m MIBI SPECT结果进行比较。15例患者中，9例（60%）Tc-99m MIBI SPECT检查结果正常，6例（40%）异常。作者发现：1）Tc-99m MIBI SPECT异常在X综合征中常见；2）运动心电图结果与Tc-99m MIBI SPECT上的灌注缺损无关；3）对于Tc-99m MIBI SPECT异常的患者，静息LVEF异常及心脏异常的发生率并不高于Tc-99m MIBI SPECT检查结果正常的患者。
