應用組織多普勒成像評價擴張型心肌病右室功能
[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.
