Summary

With economic development and rapid urbanization, air pollution has become an increasingly severe public health concern. The risk of adverse pregnancy outcomes is significantly elevated for pregnant women complicated by pulmonary hypertension. However, no studies to date have specifically examined the impact of environmental factors on pulmonary hypertension in pregnant women, nor their subsequent birth outcomes. Therefore, investigating the correlation between them holds substantial clinical and public health significance.

Detailed description

The purpose of the research is preliminary found that the correlation between air pollution and maternal outcomes in pregnant women with pulmonary arterial hypertension and provide useful information for managment of pregnant women in special ambient conditions.
