Abstract:
Objective To investigate the left ventricular (LV) performance in patients with essential hypertension(EH) by global performance index (GPI) based on three-dimensional speckle tracking imaging (3D-STI).Methods A total of 164 EH patients were enrolled and divided into four subgroups according to LV configuration:LV normal group (LVN,n =67),concentric cardiac remodeling group (CCR,n =49),concentric cardiac hypertrophy group (CCH,n =28) and eccentric cardiac hypertrophy group (ECH,n =20).Thirty age and sex matched healthy volunteers were enrolled as controls.3D-STI was performed to assess LV 3D global strain and LV torsion,then LV systolic dyssynchrony index (SDI) and global performance index (GPI) were calculated.Global strain parameters were investigated among the groups,and correlations with GPI were studied.Results GPI,global longitudinal strain(GLS),global area strain(GAS),global radial strain(GRS) and global 3D strain(G3DS) in EH groups were respectively lower than those in the normal controls,and there were statistical differences among the respective parameters (P ＜0.05,respectively).SDI in group CCH and ECH were significantly higher than that in normal controls (P ＜ 0.05,respectively).In multivariate stepwise regression analysis,GAS was the most influential to GPI.Conclusions GPI based on 3D-STI may accurately reflect LV performance in patients with EH,and has potential applications in clinical practice.
