摘要
目的:探讨在冠心病中应用超声实时三维斑点追踪技术(3DST)诊断的临床价值,对冠心病患者早期缺血心肌功能进行评估。方法:采用冠状动脉造影技术选取疑似冠心病患者60例,按照冠状造影结果将入选对象分为冠心病组40例和正常对照组20例,评估对冠心病患者采用3DST的灵敏度、特异度。结果:经3DST技术扫描分析结果显示,冠心病患者的左心室整体GLS、AGS绝对值与对照组间存在明显差异性(P<0.05);经ROC曲线分析显示GLS、AGS在AUC都在0.75~0.95间,而GLS诊断冠心病的灵敏度为85%,特异度为64%;AGS诊断冠心病的灵敏度为50%,特异度为77%,组间比较无明显差异性(P>0.05)。结论:在冠心病诊断中3DST可准确评估左心室三维病变,可定量评价早期冠心病心肌缺血致室壁功能异常状态,以评估冠心病病变发展程度。
Objective：To evaluate the clinical value of real time three dimensional speckle tracking technology in the diagnosis of coronary heart disease,and to evaluate the myocardial function of coronary heart disease patients with early myocardial ischemia.Methods：60cases of patients with suspected coronary heart disease were selected and divided into coronary heart disease group（40cases）and normal control group（20cases）according to coronary angiography results.Then evaluated the sensitivity and specificity of 3DST employed on patients with coronary heart disease（CHD）.Results：The analysis result of 3DST scanning technology showed that the absolute value of left ventricular overall GLS,AGS of coronary heart disease group and normal control group had a significant difference（P〈0.05）;The ROC curve analysis showed that both of GLS and AGS in AUC were in 0.75-0.95,the sensitivity and specificity of GLS in the diagnosis of coronary artery disease was 85%and 64%,and the sensitivity and specificity of AGS in the diagnosis of coronary artery disease was 50%and 77%,with no significant difference（P〉0.05）.Conclusion：In the diagnosis of coronary heart disease,3DST can accurately assess the three-dimensional lesions of left ventricle,which can quantitatively evaluate the abnormal state of ventricular wall function caused by early myocardial ischemia in patients with coronary heart disease,in order to evaluate the lesion development degree of coronary artery disease.
