The Risk of Adverse Pregnancy Outcomes for Long-term Exposure to Air Pollution in Pregnant Patients With Pulmonary Hypertension

China1,200 participantsStarted 2013-01-01

Plain-language 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.
