Objective: 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.
Methods: 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,.
Results: 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.
Conclusions: 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.
