【摘要】 目的 初步探讨高温超导心磁图仪在冠心病诊断及冠脉介入治疗术后随访中的应用。方法人选初步诊断为冠心病拟择期行冠脉造影检查的患者83例,根据冠脉造影结果分为对照组(24例)和冠心病组(59例,其中52例患者进行冠脉介入治疗)。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,分别于冠脉造影前和冠脉介入治疗术后1个月行心磁图检查,比较冠心病患者不同时刻病理性电流区域存在的强度及时间,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 冠心病组ACTM和RAM明显高于对照组,冠脉介入治疗术后1个月ACTM和RAM较介入前明显改善。结论 高温超导心磁图作为一种简单、无创、价格低、敏感性高的方法,可广泛应用于冠心病的诊断及冠脉介入术后治疗效果的评估。更多还原

【Abstract】 Objective To investigate the value of high temperature superconductor magnetocardiography(HTS-MCG) in the diagnosis of coronary artery disease(CAD) and the follow-up after percutaneous coronary intervention(PCI).Methods 83 patients who were diagnosed as CAD and scheduled for coronary angiography(CAG) were enrolled.All the patients were divided into control group(24 cases) and CAD group(59 cases) according to the CAG and 52 patients undergone PCI.HTS-MCG were proformed before CAG and 1 month later after PCI.Two quantitative indicators were analyzed:average classification of total maps(ACTM) and ratio of abnormal maps(RAM).Results The ACTM and RAM of CAD group were higher than those of control group.The ACTM and RAM after PCI were lower than those of before PCI.Conclusion HTS-MCG is an easy,noninvasive method with low-price and high sensitivity,and might be widely applied in the diagnosis of CAD and evaluating the effect of PCI.更多还原
