Abstract:
OBJECTIVE:To analyze the characteristics of left ventricular rotation and twist in patients with essential hypertension (EH) of different left ventricular configurations by 3-dimensional speckle tracking echocardiography (3D-STE).
METHODS:A total of 106 EH patients were divided into 4 groups: a left ventricular normal configuration (LVN) group (n=30), a concentric remodeling (CCR) group (n=31), a concentric hypertrophy (CCH) group (n=29), an eccentric hypertrophy (ECH) group (n=16), and a control group of 30 healthy subjects. The parameters of LVEF, peak basal rotation (Prot-B), peak apical rotation (Prot-A), left ventricular peak apical rotation (LV-rot), and left ventricular peak apical twist (LV-tw) were compared.
RESULTS:The left ventricular mass index in the EH groups, which kept increasing, was higher than that in the normal control group (P<0.05). Compared with the normal control group, LVN and ECH group, the left ventricular posterior wall thickness, interventricular septum at end-diastole, and relative wall thickness significantly increased in the CCH and CCR group (P<0.05). LVEF showed no significant difference among the normal control, LVN, CCR and CCH group (P>0.05), but LVEF was lower in the ECH group than in other groups (P<0.05). Compared with the normal control group, Prot-B, Prot-A, LVrot and LVtw were significantly higher in the LVN, CCR and CCH group (P<0.05), but decreased in the ECH group (P<0.05).
CONCLUSION:3D-STE can evaluate the left ventricular rotation and twist in EH patients with different configurations, and reflect changes in the left ventricular systolic function in EH of different configurations.
