摘要
报告25例正常人及25例DCM患者作^(99m)Tc-MIBI心肌断层显像及门电路心血池显像检查结果。心肌断层显像发现DCM患者左心室心肌放射性分布异常以斑块样改变为主(占75％)。其左心室的收缩、舒张功能及收缩协调性均明显低于正常人(P<0.05),左心室局部射血分数均普遍性降低功能(P<0.05)。认为^(99m)Tc-MIBI心肌断层显像结合心血池显像对DCM的诊断有一定的意义。
25 patients with dilated cardiomyopathy (DCM) and 25 normal controls were studied with Tc-99m MIBI SPECT imaging and gated radionuclide ventriculography. Myocardial SPECT imaging showed that the abnormalities of the patients with DCM are dominated by patch-pattern(75%). Patients with DCM demons rated a marked deterioration in left ventricular systolic, diastolic and synchronous functions compared with control group (P<0.05); and the regional EF of the left ventricle in DCM is significantly lower than that in controls (P<0.05). Authors believe that Tc-99m MIBI SPECT imaging combined with gated nuclide ventriculography may be of value in non-invasive diagnosis of DCM.
