【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481例正常孕妇,32例心血管疾病孕妇以及100例正常产妇纳入本研究。根据孕周分为28~31+6周、32~34+6周、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(P0.05);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(P0.05);正常孕妇HR和S1/S2呈正相关(r=0.295,P=0.000);HR和D/S呈负相关(r=-0.393,P=0.000);S1/S2和D/S呈负相关(r=-0.406,P=0.000)。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(100%,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。
[Abstract]:Objective: to investigate the value of cardiac phonogram test (PCGTT) in the detection of CCR in late pregnant women. Methods: 481 normal pregnant women at week 2841 6 were selected. Thirty-two pregnant women with cardiovascular disease and 100 normal pregnant women were included in this study. According to the gestational age, they were divided into 2831.6 weeks and 3234.6 weeks. The changes of HRS _ 1 / S _ 2 and D / S in pregnant and parturient women and the relationship between them were analyzed by measuring PCGT in 4 groups at the 6th week and postpartum. According to the CCR index test data of normal pregnant women, 95% reference values of different gestational weeks of normal pregnant women were obtained. Results: there was no significant difference in HRS1 / S2D- S between normal pregnant women with different gestational weeks (P 0.05). Compared with postpartum women, the HR of normal pregnant women with different gestational weeks was significantly higher than that of postpartum women, and S 1 / S 2 increased and D / S decreased, and the difference was statistically significant (P 0.05). There was a positive correlation between HR and S _ 1 / S _ 2 in normal pregnant women. There was a negative correlation between HR and D / S. S _ 1 / S _ 2 and D / S were negatively correlated with r-0.406. PCGT was used to measure the CCR index of normal pregnant women. The reference value range of 95% for different gestational weeks of pregnant women in the third trimester of pregnancy was the normal standard. The abnormal rate of HR in pregnant women with cardiovascular disease was 28.60.The abnormal rates of S 1 / S 2 and D / S were 63.6% and 85.7% respectively, and the CCR was completely normal in 6 cases (18.75%). The cardiac function of 26 patients with abnormal CCR index was 81.25%, and the cardiac function grade 鈪，
