Value of Quantitative Echocardiography in Analyzing Cardiac Structure and Function in Patients with Renal Failure Undergoing Maintenance Dialysis
Objective:To analyze the value of quantitative echocardiography in assessing cardiac struc-ture and function in patients with renal failure undergoing maintenance dialysis.Methods:A total of 122 renal failure patients receiving maintenance dialysis at our hospital from November 2021 to March 2024 were select-ed as the study group,and 143 renal failure patients who had not undergone maintenance dialysis during the same period were selected as the control group.All subjects underwent quantitative echocardiography to obtain cardiac structure and function parameters,and these parameters were compared between the two groups.Re-sults:The study group had higher aortic root diameter(AAo),left ventricular posterior wall thickness(LVPW),and interventricular septal thickness(IVS)compared to the control group(P<0.05).There were no statistically significant differences in aortic root diameter(AARd),left atrial anteroposterior diameter(LA),left ventricular end-diastolic diameter(LVDd),or left ventricular end-systolic diameter(LVDs)be-tween the two groups(P>0.05).The study group had higher values for right ventricular outflow tract velocity time integral(VTI),early diastolic pulmonary regurgitation velocity,late diastolic pulmonary regurgitation ve-locity,right ventricular ejection time(ET),right ventricular acceleration time(AT),tricuspid annular plane systolic excursion(TAPSE),fractional shortening(FS),left ventricular ejection fraction(LVEF),aortic ve-locity,pulmonary artery velocity,E peak,and A peak compared to the control group(P<0.05).There was no significant difference between the two groups in terms of maximum tricuspid regurgitation velocity(TRv-max)or left ventricular end-diastolic volume(LVEDV)(P>0.05).The E/A ratio,left ventricular end-systolic volume(LVESV),and pulmonary vascular resistance(PVR)were lower in the study group than in the control group(P<0.05).Conclusion:Quantitative echocardiography can provide comprehensive cardiac structure and function parameters,enabling accurate assessment of cardiac function and structure in patients with renal failure undergoing maintenance dialysis.
