Abstract:
Objective To explore the relationship among left ventricular(LV) peak systolic strain rate,the mitral annular motive amplitude(MAMA) and left ventricular ejection fraction(LVEF) in essential hypertension patients with different left ventricular patterns.Methods According to level of LV mass index and relative wall thickness,40 patients with hypertension were divided into patterns of normal geometric LV(LVN) and remodeling LV(LVR),20 normal patients were on control group. The apical views were used to determine MAMA and peak systolic strain rate(SSR).MAMA was determined by anatomic M-mode(AMM) and strain rate imaging was applied for obtaining SSR of LV basal and middle segments.LVEF was determined by Simpson rule.The LV systolic function was evaluated by mean of MAMA,SSR and LVEF. Results In all subjects,mean SSR by strain rate imaging of LV wall correlated negatively with mean MAMA(r=(-0.91),P(0.05)).Conclusions Strain rate imaging provides a sensitive,simple and trust tool to assess globle LV function in patients with essential hypertension.
