目的:探讨高龄孕妇心力储备功能的变化情况,为降低孕期并发症,提高围产保健质量提供依据。方法:收集2012年9月~2013年5月在郑州大学第三附属医院做围产保健的高龄孕妇85例及正常育龄期孕妇115例的相关资料,在静息状态下获取孕妇心音图并测量D/S值(舒张期时限/收缩期时限)。结果:①不同年龄组D/S值分别为1.50±0.09、1.47±0.17、1.44±0.13、1.36±0.11、1.28±0.11,各年龄组D/S值比较存在统计学差异(χ2=40.747,P=0.00);②高龄组与对照组在28~31+6周、32~35+6周、≥36周D/S比值有统计学差异(P<0.05),<28周时,两组D/S值无统计学差异(P﹥0.05)。结论:①随着年龄的增加,孕妇的心脏储备功能下降;②高龄孕妇的心脏储备功能明显低于正常育龄期孕妇。
Objective: To investigate the changes of heart function in elderly pregnant women, and to provide basis for reducing the complications during pregnancy and improving the quality of perinatal care. Methods: From September 2012 to May 2013, 85 cases of elderly pregnant women and 115 normal pregnant women were enrolled in the Third Affiliated Hospital of Zhengzhou University. The pregnant women’s phonocardiogram was collected at rest and measured D / S value (diastolic time / systolic time limit). Results: ①The D / S values of different age groups were 1.50 ± 0.09,1.47 ± 0.17,1.44 ± 0.13,1.36 ± 0.11,1.28 ± 0.11 respectively, there was significant difference in D / S value among all age groups (χ2 = 40.747, P = 0.00). ② The D / S ratio of the elderly group and the control group at 28-31 + 6 weeks, 32-35 + 6 weeks, and ≥36 weeks had statistical significance (P <0.05) / S value was no significant difference (P> 0.05). Conclusion: ①With the increase of age, pregnant women’s cardiac reserve function decreased; ② elderly pregnant women’s cardiac reserve function was significantly lower than that of normal pregnant women.
