Evaluation Of Left Ventricular Function In Patients With Uremia With Different Dialysis Time By Two-dimensional Speckle Tracking Technique

Objective:To evaluate the left ventricular systolic function in patients with uremia with different dialysis times.Methods:30 patients with uremia who underwent maintenance hemodialysis were divided into three groups according to different dialysis time:(1)dialysis time <1 year(group A)10cases;1 year ? dialysis time ? 3 years(group B)10 cases;dialysis time> 3 years(C group)in 10 cases.30 cases of healthy volunteers were selected as the normal control group(N group),and the clear three-lobe,apical three-chamber,apical two-chamber and left ventricular short-axis mitral valve level,papillary muscle level and apical level were collected and stored Two-dimensional dynamic images were used to analyze and measure the longitudinal,radial and circumferential strain peaks of systolic length of left ventricular septum.Results:Compared with the control group,there was no significant difference between the A group and the B group(P> 0.05).The peak value of the whole circumferential strain was significantly lower than that of the control group(P> 0.05)There was no significant difference between group B and control group and group C(P> 0.05).There was no significant difference between the two groups(P> 0.05).Conclusion:Two-dimensional speckle tracking technique can accurately evaluate the left ventricular systolic function in patients with uremia at different dialysis times,and help the clinicians to make early intervention and treatment for patients with left ventricular dysfunction caused by prolonged dialysis.
