缺血性和非缺血性心肌病核素心肌断层显像的定量分析

The Ouantitative Analysis of Radionuclide Myocardial Perfusion Imaging in Ischemic and Nonischemic Cardiomyopathy

本文回顾性地分析了24例缺血性心肌病（ISCM）和21例非缺血性心肌病（NISCM）患者的核素心肌断层显像与超声心动图，并且结合53例正常对照组心肌定量结果进行了定量分析，结果显示陈旧性心梗组（OMI）、高血压病组（EN）和扩张性心肌病组（DCM）的左室扩大，腔／壁比值分别是2、13±0．44、2．25±0．38及2．78±0．70与正常对照组的1．05±0．17比较有显著性差异（P＜0．01）。OMI组心肌定量分析见171个减低及缺损区。每个患者病变区数占自身总区数的11．60％～61．10％，平均27．16％，DCM组左室呈不均匀性分布，定量分析有27个减低区，每个患者病变心肌数占3．50％～11．52％，平均6．39％。两组分布存在显著性差异（P＜0．01）；EH组定量显像有52个增强区，每个患者心肌增强的区数占17．20％～50％，平均31．28％，DCM组有21个增强区，每个患者心肌增强的区数占0～10．72％，平均7．8％，两组分布有显著性差异（P＜0．01）。

24 patients with ischemic cardiomyopathy (ISCM) and 21 patients with nonischemic cardiomyopathy were evaluated by quantitative rest myocardial perfusion imaging. The results showed that there were 171 uptake decrease and defect regions in ISCM and 27 regions in dilated cardiomyopathy (DCM) (P<0.01). Patients with old myocardial infarction had more decrease and defect regions (11.60%～61.10% per patients, average 27.16%) than did patients with DCM (3.50%～11.52% per patient, avreage 6.39%). There were 52 uptake increase regions in patient group with essential hypertention and 21 regions with DCM (P<0.01). Patients with EH had more increased uptake regions(17.20%～50% per patient, average 1.23%) than did patients with DCM(0～10.72% per patient, average 7.84%).
