Correlation Between Age and Ventricular Diastolic Function Measured by Tissue Doppler Imaging

Objective To explore the correlation between age and left and right ventricular diastolic function indexes measured by tissue Doppler imaging in normal individuals.Methods Fifty and seven healthy participants aged from 16 to 74 years were included in the study.Each participant underwent pulsed wave Doppler examination of mitral inflow,tricuspid inflow,then underwent tissue Doppler imaging of the mitral,tricuspid annulus.Results There was good correlation between age and ventricular diastolic function indexes measured by tissue Doppler imaging(r=-0.73,P0.001).Conclusion This study shows that age has important influence on ventricular diastolic function indexes measured by tissue Doppler imaging in normal individuals and should be considered in the evaluation of left and right ventricular diastolic function
