OBJECTIVES: To investigate the duration of atrial electromechanical delay (EMD) and left atrial mechanical function in patients with preeclampsia. MATERIALS AND METHODS: This study included 26 pregnant women with preeclampsia and 24 age-matched pregnant women without preeclampsia (control group). Atrial electromechanical coupling (PA) and intra-atrial and interatrial EMD were measured using tissue Doppler echocardiography. P-wave dispersion (PWD) was measured via 12-lead electrocardiography. All data were analyzed using SPSS v.15.0 for Windows (SPSS, Inc., Chicago, Ill., USA). Differences in continuous variables between groups were examined using a nonparametric Mann-Whitney U test. Correlation analysis was performed using Spearman's coefficient of correlation. Categorical values were compared using a χ2 test. RESULTS: PA lateral and PA septal durations were significantly longer in the preeclampsia group than in the control group [74.6 ± 8.1 vs. 62.3 ± 5.3 ms (p < 0.001) and 59.7 ± 5.3 vs. 56.2 ± 4.9 ms (p = 0.005), respectively]. The duration of interatrial EMD and intra-atrial EMD in the preeclampsia group was significantly longer than in the control group [25.4 ± 4.6 vs. 13.2 ± 3.9 ms (p < 0.001) and 10.5 ± 1.9 vs. 7.1 ± 1.2 ms (p < 0.001), respectively]. PWD was significantly higher in patients with preeclampsia (43.1 ± 9.1 ms) than in the controls (37.6 ± 7.9 ms; p = 0.008). There was a significant correlation between PWD and interatrial EMD and intra-atrial EMD [r = 0.46 (p < 0.001) and r = 0.39 (p < 0.001), respectively]. CONCLUSION: The duration of atrial EMD and PWD was prolonged in patients with preeclampsia.
