Clinical value of speckle tracking imaging on left ventricular prolate axis portrait change of hypertension patients

Objective To investigate the clinical application of speckle tracking imaging(STI) in estimating left ventricular remodeling of hypertension.Methods High frame rate images were recorded from the LV apical two-,three-and four-chamber view.Peak systolic strain of each segment was acquired,average strain value of three consecutive cardiac cycles was calculated as the peak systolic strain.The average strain values of the three LV long axis levels were calculated as the LV global LS.Results There was no significant difference between group A and N on average LS values of long axis levels(P 0.05),but above indexes in group B to D were larger than those of group N and consecutive decrement from group A to D(all P0.05).Conclusions STI has the potentiality to be used to evaluate the LV systolic function in hypertension patients with different patterns of left ventricular hypertrophic geometric models,which provides important theory evidence for clinical treatment and prevention,and has considerable substantial clinical values.
