【摘要】：目的分析尿毒症患者血液透析前、后左室内、中、外三层及整体全层心肌收缩期纵向峰值应变,探讨eSie VVI技术评价血液透析短时间内对尿毒症患者左室心肌收缩功能改变的价值。方法选取2015年10月-2016年12月在我院维持性血液透析的尿毒症患者35例,血液透析前、后1h内行超声心动图检查。常规测量LAD、LVEF、LVIDd、LVIDs、ESV、EDV、SV。声像学采集动态图像。eSie VVI软件分析获得左室17个节段收缩期纵向峰值分层应变、整体全层应变,以Excel表格形式将分析结果导出。对尿毒症患者血液透析前、后收缩期纵向峰值分层应变结果进行统计分析。结果1尿毒症患者透析后与透析前常规超声心动图参数比较LAD、LVIDd、LVIDs、ESV、EDV、SV减小差异有统计学意义(P0.05),LVEF差异无统计学意义(P0.05)。2尿毒症患者透析后与透析前分层应变参数比较血液透析后1h患者左室整体全层、内层,基底段全层、内层、中层、外层,中段全层、内层心肌收缩期纵向峰值应变均较透析前减低,差异有统计学意义(P0.05);整体中层、外层,中段中层、外层,心尖段全层、内中外三层心肌收缩期纵向峰值应变差异无统计学意义(P0.05)。结论1血液透析短时间内对左室心肌收缩功能有一定负面影响,因此需要密切观察血液透析后尿毒症患者的心脏功能情况,必要时应进行相应监测,在完成血液透析的同时,减少突发性心血管事件的发生。2 eSie VVI技术可更敏感、准确的评价尿毒症患者血液透析后左室心肌整体及局部收缩功能的改变,具有一定的临床应用价值。
[Abstract]:Objective to analyze the longitudinal peak strain of myocardial contraction in uremic patients before and after hemodialysis.To evaluate the value of eSie VVI technique in evaluating left ventricular systolic function in uremic patients in a short period of time after hemodialysis.Methods from October 2015 to December 2016, 35 patients with uremia undergoing maintenance hemodialysis in our hospital were examined by echocardiography within 1 hour before and after hemodialysis.LVEF, LVIDdN, ESVV, EDV and SVS were measured by routine method.Dynamic images. ESie VVI software was used to analyze 17 segments of left ventricular systolic peak longitudinal delamination strain and whole layer strain. The results were derived by Excel table.The stratified strain results of longitudinal peak systolic period before and after hemodialysis in uremic patients were statistically analyzed.One hour after analysis, the whole left ventricular layer of the patients was analyzed.The longitudinal peak strain of the inner layer, basal segment, inner layer, middle layer, outer layer, middle layer and inner layer were all lower than that before dialysis, the difference was statistically significant (P 0.05), the whole middle layer, outer layer, middle segment middle layer, outer layer, apical segment whole layer,There was no significant difference in the longitudinal peak strain between the three layers of myocardial contraction.Conclusion (1) the left ventricular systolic function is negatively affected by hemodialysis in a short period of time, so it is necessary to observe closely the cardiac function of uremic patients after hemodialysis, and to monitor the cardiac function when necessary, so as to complete hemodialysis at the same time.The technique of reducing the occurrence of sudden cardiovascular events by using 2. 2 eSie VVI technique is more sensitive and accurate in evaluating the global and local systolic function of left ventricle after hemodialysis in patients with uremia, which has certain clinical application value.
