摘　　要：目的 比较不同部位的冠状动脉病变患者心磁图参数。方法 采用上海MEDI仪器有限公司生产的心磁图仪对99名单支冠状动脉病变患者进行心磁图检查,以91名非冠心病患者为对照组。选择T峰磁场角度、TT角度最大值、TT角度最小值、TT角度变化值、TT距离变化值、T峰最大最小比值、T峰最大电流角度、TT电流角度最大值、TT电流角度最小值、TT电流角度变化值作为参数进行分析,比较左前降支(LAD)组(n=44),左回旋支(LCX)组(n=25),右冠状动脉(RCA)组(n=30)和对照组(n=91)的心磁图结果。结果 与对照组比较,LAD组T峰磁场角度显著高于对照组(P<0.01)。LCX组T峰磁场角度、TT电流角度最大值和TT电流角度变化值均显著高于对照组(均P<0.01)。RCA组TT角度最小值和TT距离变化值显著低于对照组(均P<0.01),而TT电流角度最大值和TT电流角度变化值显著高于对照组(均P<0.01)。LCX组T峰磁场角度高于LAD组和RCA组(分别P<0.01;P<0.05)。RCA组TT距离变化值显著低于LAD组(P<0.01)。结论 不同部位冠状动脉病变的心磁图部分参数有显著差异。AIM To investigate the change of magnetocardiography(MCG)parameters in patients with lesions in different coronary arteries.METHODS 99 CHD patients with monovascular lesion were recruited to test the diagnostic accuracy of 10 MCG parameters(Map angle on T peak,TT_Map angle maximum,TT_Map angle minimum,TT_Map angle dynamics,TT_Distance dynamics,Maximum-tominimum ratio on T peak,Current angle at T peak,TT_Current angle maximum,TT_Current angle minimum and TT_Current angle dynamics),with 91 non-CHD patients serving as a control group.CHD Patients were divided into a LAD group(n=44),a LCX group(n=25),and a RCA group(n=30).RESULTS Compared to the control group,Map angle on T peak was significantly higher in the LAD group(P<0.05)and the LCX group(P<0.01).TT_Map angle maximum and TT_Map angle dynamics were also higher in the LCX group,compared to the control group(all P<0.01).In the RCA group,TT_Map angle minimum and TT_Distance dynamics were significantly lower(all P<0.01),whereas TT_Current angle maximum and TT_Current angle dynamics were higher(all P<0.01),compared to the control group.Map angle on T peak was significantly lower in the LAD group and the RCA group,compared with the LCX group(respectively,P<0.01,P<0.05).TT_Distance dynamics was lower in the RCA group,compared to the LAD group(P<0.01).CONCLUSION There were numerous parameters altered in patients with lesions in different coronary arteries.
