  •   AIM  To evaluate the clinical value of left atrial function in patients with preeclampsia by two-dimensional speckle tracking technique.   METHODS  A total of 33 patients with preeclampsia admitted to Air Force Medical University Tangdu hospital were included in the study group and other 35 age and gestational week matched normal pregnant women served as the control group. The conventional ultrasound parameters were measured by Esaote MyLab Twice Color Doppler Ultrasonography. The original data were imported into the machine with original format of Archive and the left atrial strain was analyzed.   RESULTS  Compared with those in the healthy control group, the left ventricular end- diastolicdiameter and E(P<0.05), left atrial volume index and E/ e’ were significantly increased in patients with preeclampsia (P<0.01). However, no significant difference was observed in the left ventricular end- systolicdiameter, ejection fraction and E/A between the two groups. Moreover, compared with those in the healthy control group, the left atrial strain reserve function (54±18)% vs. (76±21)%, P<0.01), conduit function (26±19)% vs. (39±19) %, P<0.05) and pump function (28±11)% vs.( 37±19)%,P<0.05) were significantly reduced in patients with preeclampsia, indicating a significant difference.   CONCLUSION  Two-dimensional speckle tracking technology can be used to assess the reserve function, channel function and pump function of left atrial strain in patients with preeclampsia at early stage, which has important clinical application value for the evaluation of left atrial function changes.
