Abstract:
Objective:To explore the clinical value of 2D-STI and RT-3DE in evaluation of left ventricular longitudinal systolic function and synchrony in hyperthyroidism patients.Methods:From July 2018 to August 2019, 93 patients with hyperthyroidism were selected as hyperthyroidism group, and 93 healthy volunteers were selected as control group at the same time.2D-STI and RT-3DE were performed to obtain the parameters of left ventricular longitudinal systolic function and synchrony, and the differences between the two groups were compared.Results:There were no statistically significant differences in left atrial diameter(LAD), left ventricular end systolic diameter(LVEDS), diastolic diameter of left ventricle(LVEDD), interventricular septum thickness(IVST) and left ventricular ejection fraction(LVEF) between the two groups (all P>0.05).2D-STI showed that the longitudinal systolic peak of multiple segments of left ventricle in the hyperthyroidism group was significantly earlier than that in the control group[posterior basal segment: (15.27±3.21)% vs.(20.38±4.19)%, t=9.336, P<0.001; lateral basal segment: (16.54±4.68)% vs.(21.26±5.65)%, t=6.204, P<0.001; anterior septal basal segment: (12.84±5.26)% vs.(18.43±6.06)%, t=6.718, P<0.001; posterior middle segment: (16.44±5.13)% vs.(22.75±6.06)%, t=7.664, P<0.001; middle anterior septum: (12.03±4.41)% vs.(19.25±5.16)%, t=10.257, P<0.001; apical inferior wall: (14.36±5.06)% vs.(21.46±6.28)%, t=8.489, P<0.001; apical cap: (9.43±5.28)% vs.(12.35±6.43)%, t=3.384, P<0.001]. Compared with the control group, the 2D-STI synchronization parameter Tls-16-SD of the hyperthyroidism group was significantly longer[(82.45±15.25)%, (52.45±10.65)%, t=15.553, P<0.001]. RT-3DE showed that the peak longitudinal contraction of multiple segments of left ventricle in hyperthyroidism group was significantly lower than that in the control group[front wall basal segment: (11.48±5.33)% vs.(19.17±6.49)%, t=8.830, P<0.001; side wall basal segment: (15.62±3.77)% vs.(22.08±4.56)%, t=10.529, P<0.001; the middle section of the bottom wall: (15.65±3.37)% vs.(18.39±4.25)%, t=4.871, P<0.001; the middle section of the posterior interval: (14.39±5.36)% vs.(19.62±3.38)%, t=7.959, P<0.001; the apex of the front wall segment: (11.17±5.54)% vs.(18.29±6.24)%, t=8.228, P<0.001; apical segment of ventricular septum: (14.67±5.38)% vs.(20.53±4.34)%, t=8.175, P<0.001]. RT-3DE synchronization parameter Tmsv-16-SD in the hyperthyroidism group was significantly longer than that in the control group[(84.36±16.08)%, (55.27±11.17)%, t=14.328, P<0.001]. Conclusion:2D-STI and RT-3DE can objectively evaluate left ventricular longitudinal systolic function and synchrony in patients with early hyperthyroidism.
