Speckle tracking imaging evaluation of left ventricular long- axis systolic and diastolic function in patients with essential hypertension

Objective To assess left ventricular long- axis function in patients with essential hypertension using speckle tracking imaging. Methods According to the left ventricle mass index( LVMI),60 patients with essential hypertension were enrolled to divide into the left ventricular hypertrophy group( n = 30) and the non- left ventricular hypertrophy group( n = 30). The systolic peak longitudinal strain( SLs),systolic peak longitudinal strain rate( SrLs),early diastolic peak longitudinal strain rate( SrLe) of 18 segments of left ventricular four- chamber view,apical two- chamber view and apical long- axis view were obtained by 2D- speckle tracking soft in QLBA 8. 1 workstation. 40 health individuals were chosen to be the control group. Results Compared with the control group,SLs,SrLs and SrLe of left ventricular segments in essential hypertension group decreased the differences were statistically significant( P 0. 05); Compared with the non- left ventricular hypertrophy group,SLs,SrLs and SrLe of left ventricular segments decreased in hypertrophy group,and the differences were statistically significant( P 0. 05). Conclusion Speckle tracking imaging can assess left ventricular long- axis systolic and diastolic function in patients with essential hypertension.
