摘要/Abstract

摘要： 本文对超声心动图（UCG）结合心电图（ECG）在鉴别扩张性心肌病（DCM）和缺血性心肌病（ICM）中的应用价值进行了分析。研究对象为回顾性选取2015年12月~2018年12月本院DCM组和ICM组患者各80例，两组均给予UCG和ECG检查并分析比较其表现。结果显示，DCM组室壁节段性运动障碍、左室心尖圆而薄、左室圆拱门形、室壁矛盾运动发生率明显低于ICM组，DCM组弥漫性室壁运动障碍、左室球形发生率明显高于ICM组，差异有统计学意义（P<0.05）；DCM组左心房内径、左心室舒张期内径、左心室收缩期内径、右心室内径、二尖瓣E点至室间隔间距、E/A、RV6、RV6/RMAX明显高于ICM组，DCM组主动脉、左心室射血分数、每搏量明显低于ICM组，差异有统计学意义（P<0.05）；DCM组主动脉瓣、二尖瓣、三尖瓣反流程度明显高于ICM组，差异有统计学意义（P<0.05）；四格表法结果显示，UCG结合ECG鉴别DCM和ICM的敏感度、特异度、准确度为97.50%、96.25%和96.88%，与实际结果基本相同，差异无统计学意义（P>0.05）。本文证实了UCG结合ECG监测可为鉴别DCM和ICM提供重要的参考依据，可作为鉴别DCM和ICM的重要手段。

Abstract: The application of echocardiography (UCG) combined with electrocardiogram (ECG) in the differential diagnosis of dilated cardiomyopathy (DCM) and ischemic cardiomyopathy (ICM) was analyzed. 80 cases of DCM (group DCM) and ICM (group ICM) in our hospital were selected as the subjects of study from December 2015 to December 2018. The two groups were examined by UCG and ECG and analyzed and compared. The results showed that the incidence of ventricular wall segmental dyskinesia, left ventricular apical round and thin, left ventricular circular arch, and ventricular wall motion of DCM group was significantly lower than ICM group, the incidence of diffuse ventricular wall movement disorder and left ventricle sphericity of group DCM was significantly higher than that ICM group, the difference was statistically significant (P<0.05). The left atrial diameter, left ventricular diastolic diameter, left ventricular systolic diameter, right ventricular diameter, mitral valve E point to interventricular septum spacing, E/A, RV6 and RV6/RMAX of DCM group were significantly higher than those in ICM group, the aorta, left ventricular ejection fraction and stroke volume of DCM group were significantly lower than that in group ICM, the difference was statistically significant (P<0.05). The degree of reflux of aortic valve, mitral valve and three tips of DCM group was significantly higher than that ICM group, the difference was statistically significant (P<0.05). Table four showed that the sensitivity, specificity and accuracy of UCG combined with ECG to identify DCM and ICM were 97.50%, 96.25% and 96.88%, respectively. The results were basically the same as the actual results, the difference was not statistically significant (P>0.05). This study confirms that UCG combined with ECG monitoring can provide important reference for the identification of DCM and ICM, and can be used as an important means to identify DCM and ICM, which is worth for further clinical promotion.
