Assessment of diastolic function in hypertension patients without left ventricular hypertrophy by tissue Doppler imaging

Objective To assess the left ventricular diastolic function in hypertension patients without left ventricular hypertrophy by using tissue Doppler imaging(TDI).Methods 23 hypertension patients without left ventricular hypertrophy were enrolled.The early diastolic velocity(Ea),the late diastolic velocity(Aa) and systolic velocity(Sa) were observed with TDI.The peak early(E) and late(A) transmitral filling velocities,their ratio(E/A),isovolumic relaxation time(IVRT) and deceleration time(DT) were measured with PDI.All the data were compared with those in nineteen normal controls.Results As compared to the control group,t here was significantly statistical difference between E,A,E/A,IVRT,DT,Ea and Ea/Aa(P0.001).Conclusion TDI were reliable methods to assess left ventricular diastolic function in hypertension patients.
