1145: Evaluation of Right Ventricular Function in Essential Hypertension Patients with Different Mode of Left Ventricle by Strain Rate Imaging

To evaluate the value of strain rate imaging (SRI) in quantitatively detecting right ventricular function in hypertension (HBP) patients with different mode of left ventricle. Thirty-eitht patients with HBP were divided into 2 groups by left ventricular mass index (LVMI) and relative wall thickness (RWT); twenty-three controls were performed echo 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), strain rate (SRa) and SRe /SRa of right ventricular free wall,. Compared with controls, Ve /Va of group LVN decreased significantly, but there were no difference in Vs and Ve; compared with group LVN and controls, Ve and Ve /Va of group LVR decreased significantly, but there were no significantly difference in Vs; compared with controls, Ss,SRe and SRe/ SRa of group LVN and LVR decreased significantly, but there were no significantly difference in SRs; compared with group LVN, Ss,SRe and SRe/ SRa of group LVR decreased significantly, but there were no significantly difference in SRs. The systolic and diastolic function of RV in patients with HBP damaged with or without reconstruction; SRI can evaluated RV funciton in these patients accurately.
