26例甲亢性心脏病心肌显像探讨

目的：探讨放射性核素^99mTc-MIBI心肌断层像在甲亢性心脏病的诊断，治疗过程中的临床价值。方法：经临床诊断的甲亢并发甲亢性心脏病患者26例，并取甲亢患才20例，此作为对照组，两组均采用^99mTc-MIBI以SPECT仪进行断层显像，并对断层图像进行分析，结果：对照组甲亢未合并心脏病心肌显像示放射性分布均匀，无稀疏区及花斑样改变，甲亢性心脏病组20例心肌显像示放射性分布弥漫性不均匀或花斑样改变。结论：甲亢性心脏病基心肌损伤程度与病情轻重，治疗及时与否、病程长短呈正相关，^99mTc-MIBI心肌灌注断层显像是甲亢性心脏病心肌缺血和心肌细胞损伤诊断的必要检查手段，为甲亢性心脏病疗效观察提供可靠依据。

26 Cases Investigation on myocardium radiography for hyperthyroid heart disease

Objective To investigate the value of the application of radioactive 99m Tc-MIBI layer radiography in the diagnosis and the treatment for hyperthyroid heart disease.Methods 26 cases with hyperthyroidism complicated with heart disease and 20 cases with hyperthyroidism as controls were undergone radioactive 99m Tc-MIBI layer radiography with SPECT.Results The myocardium radiography appearance of all controlls was well distrbuted with no sparse and scattered areas;while the myocardium radiography appearance of all cases with hyperthyroidism complicated with heart showed dissfused sparse and scattered distribution.Conclusions Our results showed that myocardium injury of hyperthroid heart disease correlated well with the disease severity and the disease treatment and the stage of the disease.Besides,our results also suggested that radioactive 99m TC-MIBI layer radiography may be one of the necessary means for the diagnosis of myocardium ischemia and for myocardium injury,and may act as a reliable evidence for the effective of clinical treatment.
