摘　　要：①目的探讨尿毒症病人心肌受损程度及其意义。②方法对１２例尿毒症病人进行放射性核素９９ｍ锝－甲氧基异丁基异晴（９９ｍＴｃ－ＭＩＢＩ）心肌断层显像检查。③结果１２例病人均显示广泛性、多节段心肌损害，呈花斑样表现，并伴有局限性心肌肥厚。有１１例病人显示左心室扩大，测量左心室腔上下径及左右径分别为５．１０±０．４３ｃｍ和４．２３±０．５９ｃｍ，与正常人左心室腔测量值（上下径３．３６±０．４４ｃｍ，左右径３．０６±０．２６ｃｍ）比较，差异有极显著性（ｔ＝９．１６，５．６８，Ｐ均＜０．０１）。④结论９９ｍＴｃ－ＭＩＢＩ心肌灌注断层显像，能够较确切的评价尿毒症病人的心肌受损程度和位置，观察心室腔的大小。Objective To evaluate the degree of myocardial damage of uremic patients. Methods 12 patients with uremia were studied with 99m Tc MIBI myocardial perfusion tomographic imaging. Results The imaging results revealed that the myocardial damages in all patients were not only extensive and multi segmental (“piebald”), but often in company with regional mycardial hepertrophy. The cavities of left ventricle in 11 cases were significantly larger than that of normal subjects (horizontal diameter:4.23±0.59cm, 3.06±0.26cm respectively; frontal diameter: 5.10±0.43,3.36±0.44cm respectively) ( t=9.16,9.68,P<0.01) . Conclusion The site and extent of myocardial damage and left veatricular size can be shown correctly and clearly by 99m Tc MIBI myocardial perfusion tomographic imaging. It will be helpful for prognosis and treatment of the disease.
