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.
Abstract
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 ven-tricular 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)mea-sured 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 sys-tolic function and this may contribute to early intervention in clinical.
