目的：初步探讨高温超导心磁图仪在糖尿病患者冠脉病变术前评估及术后随访中的应用。方法入选初步诊断为冠心病，拟行冠脉造影检查的患者85例，以冠脉造影结果为金标准，确诊为冠心病者（62例）分为糖尿病组和非糖尿病组，余23例除外冠心病诊断。确诊为冠心病患者中糖尿病组（25例）中22例患者行冠脉介入治疗，3例行冠状动脉旁路移植术。非糖尿病组（37例）中32例患者行冠脉介入治疗，余5例因未达标准或拒绝手术而未行介入治疗。应用安装于磁屏蔽室内的四通道高温超导量子干涉器心磁图仪，对所有患者于冠脉造影前行心磁图检查，行介入治疗患者于冠脉介入治疗术后1月再次行心磁图检查，比较糖尿病患者和非糖尿病患者高温超导心磁图的变化，以每幅图分级的平均数（ACTM）异常电流分布图占所有电流密度分布图的比率（RAM）作为判断标准。结果糖尿病组ACTM和RAM高于非糖尿病组。冠心病患者冠脉介入治疗术后1月ACTM和RAM较介入前明显改善。结论高温超导心磁图对糖尿病合并冠心病患者冠脉介入术前评估和术后随访具有一定临床参考价值。

Objective To investigate the value of high temperature superconductor magnetocardiography (HTS-MCG) in the prediction of coronary artery lesions before coronary angiography (CAG) and the follow-up after percutaneous coronary intervention (PCI). Methods 85 patients who were primarily diagnosed with coronary heart disease (CHD) and scheduled for CAG were enrolled. According to the CAG, 62 patients diagnosed with CHD were divided into diabetes melitus (DM) group (25 cases) and non- diabetes melitus (NDM) group (37 cases). 22cases in DM group undergone PCI, while 32 cases in NDM group. HTS-MCG were performed before CAG and 1 month later after PCI. Two quantitative indicators were analyzed:average classiifcation of total maps(ACTM) and ratio of abnormal maps(RAM). Results The ACTM and RAM of DM group were higher than those of NDM group. The ACTM and RAM after PCI were lower than those of before PCI. Conclusion HTS-MCG is useful in the prediction of coronary artery lesions and evaluating the effect of PCI in patients with DM as while as CHD.
