【摘要】：目的探讨应用组织多普勒成像技术(TDI)评价扩张型心肌病(DCM)患者右室功能的临床价值。方法 DCM患者84例,根据心室的大小,分为左心型、右心型及全心型三组。健康对照组50例,取标准心尖四腔心切面,应用TDI定量分析三尖瓣前叶及隔叶瓣环处的组织运动速度。结果与正常组比较,三组DCM患者三尖瓣环处组织运动VS、VE、VE/VA均明显减低,差异有统计学意义(P0.05),并以全心型组最为显著。三组DCM患者间两两比较,全心型后间隔瓣环处VS高于右心型,左心型侧壁瓣环处VE/VA与全心型比较差异无统计学意义(P0.05),余VS、VE、VE/VA表现为全心型右心型左心型,差异有统计学意义(P0.05)。结论 TDI速度指标VS能快速评价DCM患者右室收缩功能,而VE、VE/VA能快速评价DCM患者右室舒张功能,具有重要的临床价值。
[Abstract]:Objective to evaluate the clinical value of tissue Doppler imaging (TDI) in evaluating right ventricular function in patients with dilated cardiomyopathy (DCM). Methods 84 patients with DCM were divided into three groups according to ventricular size: left heart type, right heart type and whole heart type. TDI was used to analyze the tissue motion velocity of anterior and septal annulus of tricuspid valve in 50 cases of healthy control group. Results compared with the normal group, the VS,VE,VE/VA of tricuspid annulus was significantly decreased in the three groups of DCM patients (P0.05), especially in the whole heart type group. The VS at the posterior septal annulus of the whole heart type was higher than that of the right heart type (P0.05), while the VE/VA at the left ventricular type was not significantly different from that of the whole heart type (P0.05), while the remaining VS,VE,VE/VA showed the left heart type of the right heart type (P0.05). Conclusion TDI velocity index VS can quickly evaluate right ventricular systolic function in DCM patients, while VE,VE/VA can quickly evaluate right ventricular diastolic function in DCM patients, which has important clinical value.
