摘要
目的:运用实时三维超声心动图(RT-3DE)和二维斑点追踪技术(2D-STI)评估高龄孕晚期孕妇左心室收缩功能。方法:选取20~45岁孕晚期孕妇为研究对象,另纳入年龄匹配的健康查体女性102例作为对照组。对所有纳入对象用辛普森双平面法、2D-STI及RT-3DE进行检查分析,采用t检验或Mann-Whitney U检验对比高龄孕妇与对照组受试者左室收缩功能的差异。结果:三种方法测量的左室射血分数(LVEF)组间均无统计学差异(P>0.05)。高龄孕妇较高龄对照受试者左室LSapi减低,Tmsv-16-SD%及Tmsv-16-Dif%增高(P<0.05),高龄孕妇较适龄孕妇LSbas增加(P<0.05)。结论:高龄孕妇孕晚期LVEF处于正常水平,但可能已经存在左室壁局部纵向应变减低和心肌运动同步性减低,RT-3DE及2D-STI均可早期评价左室收缩功能改变,提示临床给予早期干预。
Objective:To evaluate the left ventricular systolic function of elderly pregnant women in late pregnancy using real-time three-dimensional echocardiography(RT-3DE) and two-dimensional speckle tracking technology(2D-STI).Methods:The pregnant women in late pregnancy aged 20~45 years were selected as the study subjects,and 102 age-matched healthy women were included as the control group.Simpson biplane method,2D-STI and RT-3DE were used to evaluate the left ventricular systolic function of all subjects in our study.Differences of the left ventricular systolic function between senile gravida and control subjects were compared by t test or Mann-Whitney U test.Results:Left ventricular ejection fraction(LVEF) measured by the three methods had no statistical difference between groups(P>0.05).Compared with the older control subjects,the pregnant women showed a decrease in left ventricular LSapi,with an increase in Tmsv-16-SD% and Tmsv-16-Dif%(P<0.05).LSbas was increased in older pregnant women compared to the right-age pregnant women(P<0.05).Conclusion:The LVEF of elderly pregnant women in the late pregnancy is at a normal level,but there may already be a decrease in local longitudinal strain of the left ventricular wall and a decrease in myocardial motion.RT-3DE and 2D-STI can early evaluate the LV systolic function and this may contribute to early intervention in clinical.
