Tissue Doppler imaging in the evaluation of cardiac function in fetuses with intrauterine growth retardation / 中南大学学报(医学版)

ABSTRACT

OBJECTIVE@#To evaluate the cardiac function of fetuses with intrauterine growth retardation (IUGR) by using tissue Doppler imaging (TDI).@*METHODS@#Peak velocity in early (E) and late (A) diastole were measured by pulsed-wave Doppler, and the peak annular velocities in systole (S'), early (E') and late (A') diastole were measured by TDI. Isovolumetric contraction time (ICT), ejection time (ET), isovolumetric relaxation time (IRT) were recorded. The ratios E/A, E'/A', E/E', E/(E'× S') and myocardial performance index (MPI) were calculated.@*RESULTS@#Compared with the control group, E', A', S' and E'/A' were obviously lower (P0.05).@*CONCLUSION@#Both diastolic and systolic heart function were jeopardized in IUGR fetuses.
