Left ventricular myocardial strain in hypertension patient with different geometric patterns using speckle tracking imaging

Objective To assess left ventricular systolic function with the peak systolic strain of longitudinal、radial and circumferential in patients with essential hypertension by using speckle tracking imaging.Methods Sixty-three cases of patients with essential hypertension(EH) were enrolled,who were classified into the left ventricular hypertrophy group(n = 30) and the non left ventricular hypertrophy group(n = 33),according to the left ventricle mass index(LVMI).The peak systolic longitudinal strain(LS) 、the peak systolic radial strain(RS) and circumferential strain(CS) were measurened in left ventricular long-axis and short-axis views by STI software.Results The peak systolis longitudinal strain of segments and global of left ventricular of group B decreased compared with the control group and group A(P0.01);the peak systolic radial strain of three segments of hytension group A increased significantly composed with control group(P0.01),but RS of group B slightly decreased compared with the control group and group A(P0.01);the peak systolic circumferential strain of three segments of group B were slight lower than the control group and group A(P0.05);Conclusions Speckle tracking imaging can assess left ventricular systolic function in gloal or local regiong of essential hypertention,which have important clical significance to evaluate early the left ventricular systolic function with essential hypertention.
