【摘要】：目的应用速度向量成像技术(VVI)检测中晚孕期正常妊娠者和妊娠期高血压综合征(妊高征)病人左心室收缩功能。方法选择30例正常中晚期妊娠(20~38周)妇女作为正常妊娠组,26例中晚期妊娠的妊高征妇女作为妊高征组,另选择健康未孕妇女30例作为对照组。应用VVI分别测量各组左心室整体收缩期纵向峰值速度、峰值应变、峰值应变率。结果与对照组比较,正常妊娠组收缩期纵向峰值速度未见明显改变(P0.05),收缩期纵向峰值应变和应变率均减低,差异有显著性(F=28.43~44.24,q=6.76~8.92,P0.01);妊高征组收缩期纵向峰值速度、峰值应变和应变率均明显减低,差异有显著性(F=3.36~44.24,q=3.61~12.94,P0.05)。与正常妊娠组比较,妊高征组收缩期纵向峰值速度未见明显差异(P0.05),但纵向峰值应变、峰值应变率均减低,差异有统计学意义(q=3.97~4.35,P0.01)。结论妊高征妇女左心室心肌纵向收缩功能受损,VVI能够显示正常妊娠及妊高征孕妇左心室收缩功能的早期损伤。
[Abstract]:Objective to detect left ventricular systolic function in normal pregnant women and patients with pregnancy induced hypertension syndrome (PIH) by velocity vector imaging (VVI). Methods Thirty normal women with intermediate and late pregnancy (20 ~ 38 weeks) were selected as normal pregnancy group and 26 women with pregnancy induced hypertension syndrome (PIH) as control group, and 30 healthy non-pregnant women as control group. The longitudinal peak systolic velocity and peak strain rate of left ventricle were measured by VVI. Results compared with the control group, the peak systolic velocity in normal pregnancy group was not significantly changed (P0.05), but the longitudinal peak strain and strain rate in normal pregnancy group were decreased, the difference was significant (F < 28.43 / 44.24), and the peak systolic velocity in pregnancy induced hypertension group was 6.768.92 / P0.01, respectively. The peak strain and strain rate were significantly decreased (FN 3.36 ~ 44.24) and strain rate was 3.61 / 12.94 (P0.05). Compared with normal pregnancy group, there was no significant difference in peak systolic velocity in PIH group (P0.05), but the longitudinal peak strain and peak strain rate were all decreased, the difference was statistically significant (QP0.01). Conclusion VVI can show the early injury of left ventricular systolic function in normal pregnancy and pregnant women with PIH.
