Abstract:
Objective To evaluate the value of strain rate imaging(SRl) in quantitatively detecting regional right ventricular function in hypertension(HBP) patients with different mode of left ventricle.Methods Thirty-eight patients with HBP were divided into left ventricular nermal (LVN) and left ventricular remodeling(LVR) groups according to left ventricular mass index(LVMI) and relative wall thickness(RWT).Twenty-three controls were performed echocradiography examination.Tissue velocity imagings of all the patients and controls were accepted in apical four chamber views.The indies included:peak systolic velocity(Vs),peak early diastolic velocity(Ve),peak late diastolic velocity(Va) and Ve/Va of triscular annulus,peak systolic strain rate(SRs),peak early diastolic strain rate (SRe),peak late diastolic strain rate(SRa) and SRe/SRa of right ventricular free wall.Results Compared with controls,Ve/Va of LVN group decreased significantly,but there were no difference in Vs and Ve.Compared with LVN group and controls,Ve and Ve/Va of LVR group decreased significantly,but there were no significantly difference in Vs.Compared with controls,Ss,SRe and SRe/SRa of LVN and LVR group decreased significantly,but there was no significantly difference in SRs;compared with LVN group,Ss,SRe and SRe/SRa of LVR group decreased significantly,but there was no significantly difference in SRs.Conclusions The systolic and diastolic function of RV in patients with HBP damaged with or without left ventricular remodeling.SRI can evaluated regional right ventricular funciton in these patients accurately.
