Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Little is known about the status of maternal, obstetric and neonatal complications and the potential predictors of developing heart failure (HF) in the mothers with pulmonary hypertension in China. Eligible samples were screened from January, 2012 to December, 2021. Maternal clinical characteristics and in-and-out hospital outcomes were collected and compared in women with and without pulmonary hypertension.

The main aims of this study are as follows:

1. To investigate the perinatal diagnosis and treatment of pregnant women with pulmonary hypertension in China over the past 10 years and the maternal and infant outcomes.
2. To explore risk factors that affect the outcome of pregnant women with pulmonary hypertension in mothers and infants.
3. To summarise effective risk stratification management protocols and construct standardised strategies for the management of pulmonary hypertension in pregnancy.
4. To establish a clinical database, biobank and follow-up cohort for pregnant women with pulmonary hypertension across China.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Pulmonary hypertension is a malignant disease with a high mortality rate, difficult to diagnose at an early stage and has posed a huge economic burden on patients and society. Pregnancy with pulmonary hypertension is associated with high maternal mortality (25% - 56% ) and a high incidence of fetal complications such as preterm birth (85% - 100%), fetal growth restriction (3% - 33%) and severe outcomes such as fetal/neonatal loss (7% - 13%). A high maternal mortality rate of 30%-56% for pregnancy-related pulmonary hypertension for women and 11-28% for infants has been reported.

However, despite national and international guidelines recommending avoidance of pregnancy, some women with pulmonary hypertension persist in their pregnancies or have unplanned pregnancies, and some pregnant women are diagnosed with pulmonary hypertension only after symptoms such as heart failure have worsened. Although with the development of pulmonary arterial hypertension(PAH)-targeted drugs, the mortality rate for pregnancy-associated PAH has declined but remains relatively high. The high maternal and infant mortality rates and complication rates make it a critical condition that seriously endangers the lives of both mother and child.

Limited data in China reported the outcome, prognosis and management measures of combined pulmonary hypertension in pregnancy, and there is a lack of overall description and analysis of pregnancy with pulmonary hypertension in a multi-centre setting. The current status of high risk factors, efficacy of multidisciplinary consultation and management of maternal and fetal mortality and complications is unclear.

Therefore, the aim of this study was to retrospectively analyse the current status of the management of pregnant women with pulmonary hypertension in a multicenter setting across China, and try to summarise effective risk stratification management protocols and construct standardised strategies for the management of pulmonary hypertension in pregnancy to reduce maternal and infant mortality and adverse events and improve the prognosis of mothers and infants.
