探讨妊娠合并心力衰竭孕妇的分娩方式及其对妊娠结局的影响。

选取2017年1月至2018年1月胶州市人民医院收治的100例妊娠合并心力衰竭孕妇作为研究对象，评估其心功能分级，并统计所有孕妇分娩方式(阴道分娩和剖宫产)与不良妊娠结局(新生儿窒息、足月低体质量、早产、围生儿死亡)发生率。

100例孕妇中，心功能NYHA分级Ⅰ级10例、Ⅱ级49例、Ⅲ级29例、Ⅳ级12例。Ⅰ＋Ⅱ级孕妇阴道分娩率为52.54%(31/59)，Ⅲ＋Ⅳ级孕妇阴道分娩率为26.83%(11/41)，差异有统计学意义(P<0.05)。Ⅰ＋Ⅱ级孕妇新生儿窒息、足月低体质量、早产、围生儿死亡发生率均低于对照组，差异有统计学意义(均P<0.05)。

妊娠合并心力衰竭孕妇心功能状态可对分娩方式及妊娠结局产生显著影响，且心功能分级越高，剖宫产率与不良妊娠结局发生风险越高。

To investigate the delivery mode and pregnancy outcome in pregnant women with heart failure.

A total of 100 pregnant women with heart failure admitted to Jiaozhou People's Hospital from January 2017 to January 2018 were selected as the research objects, and the incidence of delivery modes (vaginal delivery and cesarean section) and adverse pregnancy outcomes (neonatal asphyxia, full-term low body mass, premature birth, perinatal death) were counted.

Of the 100 pregnant women, 10 were NYHA grade Ⅰ, 49 were NYHA grade Ⅱ, 29 were NYHA grade Ⅲ and 12 were NYHA grade Ⅳ. The vaginal delivery rate of grade Ⅰ+ Ⅱ pregnant women was 52.54% (31/59), and that of grade Ⅲ+ Ⅳ pregnant women was 26.83% (11/41), and the difference was statistically significant (P<0.05). The incidence of neonatal asphyxia, full-term low body mass, premature delivery and perinatal mortality of grade Ⅰ+ Ⅱ pregnant women were lower than those of the control group, and the difference was statistically significant (P<0.05).

Heart function status of pregnant women with heart failure can have a significant impact on delivery mode and pregnancy outcomes. The higher the cardiac function classification, the higher the risk of cesarean section rate and adverse pregnancy outcomes.
