超声心动图检查在诊断孕晚期妊娠期高血压疾病患者心脏形态及功能异常中的应用价值

Application value of echocardiography in the diagnosis of cardiac morphol ogy and function abnormalities in patients with hypertensive disease during the third trimester of pregnancy

目的:探讨超声心动图检查在诊断孕晚期妊娠期高血压疾病患者心脏形态及功能异常中的应用价值。方法:选取150例孕晚期妊娠期高血压疾病患者作为研究对象。将其作为妊娠期高血压疾病组,并根据病情的不同对其进行再分组。另选取同期在该院接受产检的健康孕妇50例作为对照组。然后对比各组孕妇超声心动图心脏形态学指标及功能性指标的差异。结果:1)妊娠期高血压疾病组患者、A组患者、B组患者、C组患者的SBP、DBP均高于对照组孕妇,P<0.05。C组患者的SBP、DBP均高于A组患者、B组患者,P<0.05。2)妊娠期高血压疾病组患者的室间隔舒张末期厚度(IVSTd)、左心室后壁舒张期厚度(LVPWTd)、左室舒张末期内径(LVDd)、左房前后径(LAD)、左心室质量指数(LVMI)、左心室壁相对厚度(RWT)均高于对照组孕妇,P<0.05。C组患者的IVSTd、LVPWTd、LVDd、LAD、LVMI均高于A组患者,其LVDd高于B组患者,P<0.05。3)妊娠期高血压疾病组患者超声心动图的A峰高于对照组孕妇,其超声心动图E峰与A峰的比值(E/A)、舒张早期快速充盈分数(RFF)均低于对照组孕妇,P<0.05。与A组患者相比,C组患者的超声心动图A峰更高,其E/A、RFF均更低,P<0.05。4)妊娠期高血压疾病组患者产后出血、新生儿窒息、早产等不良妊娠结局的发生率及剖宫产率均高于对照组孕妇,P<0.05。结论:超声心动图检查在诊断孕晚期妊娠期高血压疾病患者心脏形态及功能异常中的应用价值较高。

Objective:To explore the value of echocardiography in the diagnosis of cardiac morphology and functional abnormalities in patients with hypertension during the third trimester of pregnancy.Methods:150 patients with hypertension during the third trimester of pregnancy were selected as subjects.They were classified as hypertensive disorders during pregnancy,and they were subdivided according to their condition.In addition,50 healthy pregnant women were selected as the control group.Then the differences of morphological and functional indexes of echocardiography in pregnant women of each group were compared.Results:1)The SBP and DBP of hypertensive disease group,group A,group B and group C during pregnancy were higher than those of control group,P<0.05.The SBP and DBP of group C were higher than those of group A and B,P<0.05.2)The end-diastolic ventricular septal thickness(IVSTd),posterior diastolic left ventricular wall thickness(LVPWTd),end-diastolic left ventricular diameter(LVDd),anterior posterior diameter(LAD),left ventricular mass index(LVMI)and relative thickness of left ventricular wall(RWT)in the gestational hypertension group were all higher than those in the control group(P<0.05).IVSTd,LVPWTd,LVDd,LAD and LVMI in group C were higher than those in group A,and LVDd was higher than that in group B,P<0.05.3)Peak A of echocardiography in hypertensive disease group during pregnancy was higher than that in control group,and the ratio of peak E to peak A(E/A)and early diastolic rapid filling fraction(RFF)of echocardiography in hypertensive disease group during pregnancy were lower than those in control group(P<0.05).Compared with group A,group C had A higher echocardiogram PEAK A,and A lower E/A and RFF(P<0.05).4)The incidence of adverse pregnancy outcomes such as postpartum hemorrhage,neonatal asphyxia and preterm birth and the rate of cesarean s ection in the hypertensive disease group during pregnancy were higher than those in the control group(P<0.05).Conclusion:Echocardiography is of high application value in the diagnosis of cardiac morphology and functional abnormalities in patients with hypertension during the third trimester of pregnancy.
