| Objective: To explore the value of real-time three-dimensional echocardiography(real-time 3D echocardiography RT-3DE)technology and application value in the left ventricular systolic function in patients with chronic renal function evaluation and synchronicity,clinical diagnosis,diagnosis and treatment of chronic renal insufficiency in patients with myocardial damage and provide a convenient and objective.Methods: on the West Coast Medical Center Affiliated Hospital of Qiingdao University of patients,including mild patients with chronic renal insufficiency(CKD2-3),26 cases of severe patients with chronic renal insufficiency(CKD4-5)in 20 patients and 20 healthy volunteers.Two-dimensional echocardiography with ECG,practical M ultrasound,end diastolic thickness in ECG QRS wave starting point of interventricular septum(IVSTd),left ventricular end diastolic posterior wall thickness(LVPWTd),and compare the two indicators.At the same time for real-time three-dimensional echocardiography(RT-3DE),access to image,get offline analysis and compare the various indicators: left ventricular end diastolic volume(3D-LVEDV),left ventricular end systolic volume(3D-LVESV),left ventricular ejection fraction D(3D-LVEF),left ventricular systolic synchrony parameters,Tmsv16-SD%,msv16-Dif,Tmsv16-SD Tmsv16-Dif%,Tmsv12-SD,Tmsv12-SD%,Tmsv12-Dif,Tmsv12-Dif%,Tmsv6-SD,Tmsv6-SD%,Tmsv6-Dif,Tmsv6-Dif% and systolic dyssynchrony index(SDI).Results: 1 compared with the control group,CKD2-3 group IVSTd increased(t=6.035),left ventricular ejection fraction D(3D-LVEF),left ventricular end diastolic posterior wall thickness(LVPWTd),left ventricular end diastolic volume(3D-LVEDV),left ventricular end systolic volume(3D-LVESV)had no statistical significance,left ventricular systolic synchronization Tmsv16-SD,Tmsv16-SD%,msv16-Dif parameters,Tmsv16-Dif%,Tmsv12-SD,Tmsv12-SD%,Tmsv12-Dif,Tmsv12-Dif%,Tmsv6-SD,Tmsv6-SD%,Tmsv6-Dif,Tmsv6-Dif% and systolic dyssynchrony index(SDI)compared with the control group,there is significant difference(t=21.35,7.35,9.65,12.43,8.69,8.73,11.63,6.44,12.43,5.50,9.02.10.36);compared with the control group,CKD4-5 group,IVSTd end diastolic left ventricular posterior wall thickness(LVPWTd)increased(t=7.35,5.50),left ventricular end diastolic volume(3D-LVEDV),left ventricular end systolic volume(3D-LVESV)increased(t=6.44,5.35),left ventricular ejection fraction of three-dimensional(3D-LVEF)decreased(t=-5.15),left ventricular systolic synchrony parameters Tmsv16-SD,Tmsv16-SD%,msv16-Dif,Tmsv16-Dif%,Tmsv12-SD,Tmsv12-SD%,Tmsv12-Dif,Tmsv12-Dif%,Tmsv6-SD,Tmsv6-SD%,Tmsv6-Dif,Tmsv6-Dif% and systolic non synchronization index(SDI)compared with the control group,there were significant differences(t=20.21,8.45,7.45,11.34,6.59,6.73,10.83,5.64,11.73,4.56,8.42,12.35);compared with CKD2-3 group,CKD4-5 group,IVSTd end diastolic left ventricular posterior wall thickness(LVPWTd),t=4.035(.5.614),left ventricular end diastolic volume(3D-LVEDV),left ventricular end systolic volume(3D-LVESV)increased(t=5.041,6.321),left ventricular ejection fraction D(3D-LVEF)decreased(t=-4.63),left ventricular systolic synchrony parameters Tmsv16-SD,Tmsv16-SD%,msv16-Dif,Tmsv16-Dif%,Tmsv12-SD,Tmsv12-SD%,Tmsv12-Dif,Tmsv12-Dif%,Tmsv6-SD,Tmsv6-SD%,Tmsv6-Dif and Tmsv6-Dif% compared with the control group there were significant differences(t=15.21,7.65,6.55,10.44,6.79,7.75,8.83,4.68,13.83,5.56.6.43,11.85).Conclusion: the early stage of chronic renal insufficiency in patients with left ventricular ejection fraction while normal,but the synchronization parameters showed that the left ventricular systolic function was impaired,and as the disease progresses,there are already signs of cardiac remodeling,ejectionfraction and impaired heart function;real-time three-dimensional echocardiography can accurately and conveniently and quickly evaluate changes in different stages of chronic renal insufficiency patients with left ventricular systolic function. |
