Evaluation of Left Ventricular Function by Three-Dimensional
Speckle-Tracking Echocardiography in Patients with Chronic Kidney
Objective To establish a quantitative evaluation of the left ventricle’s
systolic function in patients with chronic kidney failure (CKF) by
three-dimensional speckle-tracking echocardiography(3D-STE). Methods
Two-dimensional transthoracic echocardiography and three-dimensional
transthoracic echocardiography were performed on 30 patients with CKF.
The ejection fraction (EF), mass and global peak longitudinal strain
(GL), global circumferential strain (GC), global area strain (GA), and
global radial strain (GR) of the left ventricle were calculated. Results
(1) EF, GL, GC, GA, and GR in the CKF group were significantly lower
than in the control group. Meanwhile, GL, GC, GA, and GR were well
correlated with EF. (2) For patients with normal EF in the CKF group,
GL, GC, GA, and GR were lower than in the control group, while the left
ventricular mass was significantly higher than in the control group. (3)
For patients with hypertension in the CKF group, EF, GL, GC, GA, and GR
calculated using three-dimensional echocardiography were significantly
lower than in patients with normal blood pressure; however, the
myocardial mass was higher. Conclusions Parameters calculated using
three-dimensional speckle-tracking software were lower in the CKF group.
Simultaneously, the left ventricular mass was higher than in the control
group, showing that the myocardial contraction function was impaired and
that myocardial reconstruction occurred.
