摘　　要：目的探讨超声心动图鉴别诊断扩张型心肌病(DCM)与心室肌致密化不全(NVM)的临床应用效果。方法回顾性分析,抽取2017年3月至2019年6月于我院确诊的34例DCM患者作为DCM组及同期确诊的30例NVM患者作为NVM组,所有患者均进行超声心动图检查,观察分析2组的超声心动图检查结果。结果DCM组与NVM组的左室射血分数(LVEF)对比,差异无统计学意义(P>0.05);NVM组的左室扩大、室壁厚度、心内膜层最大厚度与致密化的心外膜层厚度比值(N/C)均较DCM组高,差异有统计学意义(P<0.05);将2组超声心动图表现比较有差异的变量作为检验变量,将DCM作为状态变量,绘制ROC曲线得到各检验变量(左室扩大、室壁厚度、N/C)鉴别诊断DCM的曲线下面积分别为:0.784、0.827、0.803,均>0.7,鉴别诊断效能高。结论超声心动图可有效鉴别诊断DCM与NVM,具有较高的临床应用价值。Objective To explore the clinical effect of echocardiography in differential diagnosis of dilated cardiomyopathy(DCM)and ventricular insufficiency of densification(NVM).Methods Retrospective analysis,34 DCM patients confirmed in our hospital from March 2017 to June 2019 were selected as DCM group and 30 NVM patients confirmed in the same period as NVM group.All patients were examined by echocardiography,and the results of echocardiography in the two groups were observed and analyzed.Results There was no significant difference in left ventricular ejection fraction(LVEF)between DCM group and NVM group(P>0.05);the ratio of left ventricular enlargement,wall thickness,maximum endocardial layer thickness to dense epicardial layer thickness(n/C)in NVM group was higher than that in DCM group.The area under the curve of DCM was 0.784,0.827 and 0.803 respectively,all of which were>0.7.The efficiency of differential diagnosis was high.Conclusion Echocardiography can effectively differentiate DCM from NVM,and has high clinical value.
