摘 要:目的探讨全容积三维超声心动图(FV3DE)评价正常妊娠左室收缩功能的应用价值。方法选取55例健康孕妇,其中早孕期18例(早孕组),中孕期18例(中孕组)、晚孕期19例(晚孕组),另选取20例健康未孕妇女(对照组),应用FV3DE测定四组左室收缩功能参数及一般血流动力学指标。结果FV3DE成像满意率:对照组为100.0%(20/20),早孕组为100.0%(18/18),中孕组为88.9%(16/18)、晚孕组为78.9%(15/19)。与对照组比较,早、中、晚孕组心率明显增高(P〈0.05),总外周阻力(TPR)逐渐降低(P〈0.05),左室心肌质量(LVM)、左室心肌质量指数(LVMI)、左室舒张末期容积(LVEDV)、左室每搏量(LVSV)、左室心输出量(LVCO)逐渐递增(P〈0.05),四组平均动脉压(MAP)、左室射血分数(LVEF)、峰值射血率(PER)比较差异无统计学意义(P〉0.05)。健康孕妇LVCO与TPR呈负相关(P〈0.01),与心率、LVM、LVMI、LVEDV、LVSV、LVEF、PER呈正相关(P〈0.01),PER与LVEF呈正相关(P〈0.01)。结论FV3DE在早期评估正常妊娠左室收缩功能中具有重要临床价值。Objective To investigate the value of full-volume three-dimensional echocardiography (FV3DE) in evaluating left ventricular systolic function in normal pregnancy. Methods Fifty-five healthy pregnant women,including 18 cases in first trimester (first trimester group), 18 cases in second trimester (second trimester group) and 19 cases in third trimester (third trimester group), and 20 healthy nonpregnant women (control group) were chosen. The hemodynamic indexes and left ventricular systolic function parameters were detected by FV3DE. Results The imaging satisfactory rates of FV3DE of control group, first trimester group,second trimester group and third trimester group were 100.0% (20/20),100.0% (18/18), 88.9%(16/18) and 78.9%(15/19) respectively. Compared with control group,heart rates (HR) of first,second and third trimester groups were significantly quicker (P 〈 0.05);total peripheral resistance (TPR)declined gradually (P 〈 0.05 ) ; LVM, LVMI, LVEDV, LVSV and LVCO increased gradually (P 〈 0.05 ) ; MAP, LVEF, PER of four groups had no significant differences (P 〉 0.05 ). LVCO in healthy pregnant women had negative correlation with TPR (P 〈 0.01 ),and positive correlation with HR,LVM,LVMI, LVEDV, LVSV, LVEF and PER (P 〈 0.01 ), PER had positive correlation with LVEF. Conclusion The application of FV3DE has significant clinical value in early evaluation of left ventricular systolic function in normal pregnancy.
