Abstract:
Objective To evaluate the characteristics of left ventricular systolic longitudinal strain in uremic patients and its relationship with dialysis time using three-dimensional speckle tracking echocardiography (3D-STE).Methods Forty-six uremic patients were divided into three groups according dialysis time (ranged 0-5 years):group A (≤1 year),group B (1 year＞time ≤3 years),group C (3 years ＞time≤5 years),group D was control group.The dynamic images of apical four chamber view were displayed and apical full-volume images were obtained and saved in all subjects using a full volume matrix probe.The original data was recorded and was analyzed by using off-line 3DT analysis software (TomTec 4D MV-Assessment).The longitudinal peak systolic strain and 16 segment systolic strains and strain mean value in 16 segment of left ventricular were acquired and compared.Results The peak strain of apical segment was lower than that of the basal segment and the middle segment and it had an increasing trend from the apical segment to the basal segment in three uremia groups.Instead,it had a decreasing trend from the apical segment to the basal segment in control group.But the differences were not statistically significant.The longitudinal peak systolic strain value,16 segment strain value and mean value of 16 segment strain all were lower in three uremic groups than those of control group.Every segment of 16 segment stain value in group A was higher than those of group B and C.There was no difference in every segment between B and C group in addition to basal and middle segment of anterior septum.Conclusions 3D-STE could evaluate the left ventricular systolic function in uremic patients and the cardiac function could be partly protected by regular dialysis treatment.
