3-dimensional speckle tracking echocardiography for left ventricular rotation and twist in patients with hypertension / 中南大学学报(医学版)

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 (P0.05), 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.
