Abstract:
Objective To assess left ventricular (LV) global systolic function in patients with essential hypertension with normal geometric LV by 3-dimensional ultrasound speckle tracking imaging(3D-STI). Methods Fifty patients with essential hypertension were enrolled in this study, 29 normal subjects matched with age and sex were selected as control groups. LV global longitudinal peak systolic strain (GLS), radial peak systolic strain (GRS), circumferential peak systolic strain (GCS), LV global 3-dimentional radial peak systolic strain (3DGRS) were measured in all subjects by 3D-STI from the apical full-volume image and compared between groups. LV ejection fraction (LVEF) was acquired from 3D-STI.Results Compared with controls, LV GLS, GRS, GCS and 3DGRS were significantly reduced in patients with hypertension ( P ＜ 0.05 for all). A Pearson correlate revealed that LV GCS, GLS and GRS corresponded with LVEF( r1 =0.930, P1 ＜0.001; r2 = 0.705, P2 ＜0.001; r3 =0.474, P3 =0.001,respectively) in patients with hypertension, and LV GCS, GLS correlated with LVEF( r1 = 0. 838, P1 ＜0. 001; r2 = 0. 697, P2 ＜ 0. 001, respectively) in normal subjects. Conclusions LV global 3D strain decreases in patients with hypertension in the early period,3D-STI could evaluate the early change of heart function in patients with hypertension. LV circumferential movement plays a major role in the LV 3D movement and impacts on LVEF.
