Abstract To evaluate the value of tissue Doppler for diagnosing fetal heart function of pregnant women with gestational diabetes mellitus (GDM) in plateau section. Methods: 50 pregnant women with GDM from plateau section were selected in study group, and 80 normal pregnant women with the same age and gestational weeks were selected in control group. The myocardial movement velocity (Ea,Aa,Sa peak) and Tei index of the second and tricuspid annulus of fetus were measured by tissue Doppler, and the diastolic and systolic functions of left and right ventricle of fetus were analyzed. Results: The values of movement velocity Ea, Aa, and Sa of tricuspid annulus of fetus was significant higher than that of mitral annular of fetus in both groups (P＜0.05). The values of movement velocity Ea and Aa of tricuspid annulus and mitral annular of fetus with different gestational weeks had significant different (P＜0.01), but Sa value of fetus had no significant different (P＞0.05). The values of movement velocity Ea, Aa, and Sa of tricuspid annulus and mitral annular of fetus in the study group were significant lower than those of fetus in the control group, but the value of myocardium comprehensive index of fetus in the study group was significant higher (P＜0.05). Conclusion: The systolic and diastolic function of left and right ventricle of fetus of pregnant women with GDM may be damaged. Tissue Doppler has good application value for evaluating heart function of fetus.
