智能超声定量技术评价冠心病患者左室功能

Evaluation of Left Ventricular Function in Patients with Coronary Heart Disease by lntelligent Acoustic Quantification

目的：检验智能超声定量（ＡＱｉ）技术定量诊断的准确性及其在冠心病中的应用价值。方法：应用ＡＱｉ技术对冠心病组（ＣＨＤ）和正常组（ＮＳ）各３０例受试者的左心功能进行检测，并与二维超声心动图、核素心肌灌注断层显像的研究结果对比。结果：３种方法对两组同一对象同一观察指标所测结果无显著差别（Ｐ＞０．０５）；３种方法测量的ＬＶＥＦ值高度相关（ｒ＝０．８３～０．９０）。ＣＨＤ组左室ＥＤＶ、ＥＳＶ大于ＮＳ组；ＰＦＲ、ＰＥＲ、ＬＶＥＦ均小于ＮＳ组；ＴＰＦＲ较ＮＳ组延长。两组间差异有显著性（Ｐ＜０．０５）。结论：ＡＱｉ法是实时动态评价心功能的新方法。

Abstract Objective: We studied the accuracy of quantitative diagnosis by intelligent acoustic quantification (AQi) technique and its application value for coronary heart disease. Methods: We applied
