摘要
目的:探讨孕晚期孕妇心音图试验(PCGT)检测心力储备(CCR)的价值。
方法:选择孕28~41+6周例正常孕妇,32例心血管疾病孕妇以及例正常产妇纳入本研究。根据孕周分为28~31+6、32~34+6、35~41+6周和产后4个组。PCGT测量、分析孕产妇HR、S1/S2和D/S的变化趋势以及各指标之间的关系,根据正常孕妇的CCR指标测试数据得出正常孕妇孕晚期不同孕周各指标的95%参考值范围,分析心血管疾病孕妇的CCR指标异常情况。
结果:不同孕周正常孕妇之间HR、S1/S2、D/S比较,差异均无统计学意义(P>0.05);不同孕周正常孕妇与产后妇女相比,HR增快,S1/S2增大,D/S降低,差异均有统计学意义(P<0.05);正常孕妇HR和S1/S2呈正相关(r=0.,P=0.);和D/S呈负相关(r=-0.,P=0.);S1/S2和D/S呈负相关(r=-0.,P=0.)。以PCGT测量CCR指标的正常孕妇孕晚期不同孕周各指标的95%参考值范围为正常标准,心血管疾病孕妇HR的异常率28.6%~45.5%,S1/S2和D/S的异常率63.6%~85.7%,CCR完全正常者6例(18.75%),心功能均为I级(%,6/6),CCR指标异常患者26例(81.25%),心功能I级3例(11.5%,3/26)。
结论:PCGT检测CCR作为一种无创、低廉、简单的孕晚期心脏病筛查方法具有一定价值,孕晚期孕妇PCGT检测HR、S1/S2、D/S超过参考值范围者,需考虑孕妇可能存在心血管疾病或患病隐患,但对于心功能I级的心血管疾病孕妇,PCGT检测可能出现漏诊的情况。

在我国,孕产妇死亡顺位中,妊娠合并心脏病高居第2位,位居非直接产科死因的首位[1]。除去器质性心脏疾病,妊娠相关心血管系统改变,如血容量、心率(HR)、心排出量增加可能使妊娠前无症状的心脏病患者病情加重,危及母婴安全,甚至导致许多孕产妇死于心力衰竭[2,3]。因此,精确评估孕产妇的心脏功能是产科医师和妇幼保健工作者值得北京治疗白癜风的比较专业的医院治疗白癜风哪里最好
