左心室厚度的声学超声造影评估效果分析

Analysis of the Effect of Acoustic Contrast-enhanced Ultrasound on Left Ventricular Thickness Measuring

本文探究了声学超声造影评估左心室厚度的效果,旨在提高临床测量室壁厚度的准确度。选取2018年1月~2019年5月我院心内科患者94例为研究对象,按照随机数表法将患者分为两组,对照组47例,接受二维超声心动图检测,观察组47例,接受左心声学造影检测。将左心室室壁划分为18节段,比较两组患者检测结果的准确度差异。比较两组患者心尖两腔(A2CH)切面舒张期全部阶段以及收缩期3、6、15、18阶段室壁厚度,差异具有统计学意义(P<0.05);两组患者心尖三腔(A3CH)切面舒张期4、10、13、16阶段以及收缩期4、10、16阶段室壁厚度比较,差异具有统计学意义(P<0.05);两组患者心尖四腔切面(A4CH)切面舒张期5、14、17阶段以及收缩期5、17阶段室壁厚度比较,差异具有统计学意义(P<0.05)。二维超声心动图检测在舒张期1、2、7、8、11节段以及收缩期1、2、7、8、9、11、12、13、14节段的测量结果准确可靠,而左心声学造影检测能提供更为准确的左心室厚度指标,对提高临床对左心室室壁厚度检测的准确度具有重要意义。

In order to explore the effect of acoustic contrast-enhanced evaluation on left ventricular thickness and improve the accuracy of clinical measurement of wall thickness,94 patients with cardiology were selected as subjects from January 2018 to May 2019.The patients were divided into two groups according to the random number table method.The control group(47 cases)received two-dimensional echocardiography.The observation group(47 cases)received left heart contrast echocardiography.The left ventricular wall was divided into 18 segments,and the difference in accuracy between the two groups was compared.There were significant differences in the wall thickness between the two groups in the apical two-chamber(A2CH)section and the 3rd,6th,15th,and 18th stages of systolic phase(P<0.05).There were significant differences between the two groups in the wall thickness of the 4th,10th,13th and 16th stages of apical period and the 4th,10th and 16th stages of systolic phase in the apical three-chamber(A3CH)section(P<0.05).There were significant differences in the wall thickness of the 5th,14th stages of the apical period of the apical four-chamber view(A4CH)and the 5th,17th stages of the systolic phase between the two groups(P<0.05).Two-dimensional echocardiography has accurate and reliable measurements in the 1st,2nd,7th,8th,and 11th segments of the diastolic phase and the 1st,2nd,7th,8th,9th,11th,12th,13th,and 14th segments of the systolic phase,while the left cardiac echocardiography can provide a more accurate left ventricular thickness index,which is of great significance to improve the accuracy of clinical detection of left ventricular wall thickness.
