Abstract: 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 63 cases of patients with essential hypertension(EH) were enrolled, who were classified into the left ventricular hypertrophy group (n=33) and the non left ventricular hypertrophy group (n=30), 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(P<0.01); the peak systolic radial strain of three segments of hytension group A increased significantly composed with control group(P<0.01), but RS of group B slightly decreased compared with the control group and group A (P<0.01); the peak systolic circumferential strain of three segments of group B were slight lower than the control group and group A( P<0.05); Conclusion Speckle tracking imaging can assess left ventricular systolic function in gloal or local regiong of essential hypertention with different model, which were regard as a new method to evaluate early the left ventricular systolic function with essential hypertention.
