Pregnancy outcome analysis of 94 patients with pulmonary arterial hypertension during pregnancy.

Abstract

The aim of the study was to analyze the pregnancy outcomes of patients with pulmonary arterial hypertension to provide a reference for clinical diagnosis and treatment. Clinical data of 94 patients with a pregnancy complicated by pulmonary hypertension were retrospectively analyzed. The means and percentages of the pregnancy outcomes were calculated, and the analysis of variance, Chi-square test, and Fisher's exact test were applied for comparison. The pregnancy outcomes were less favorable in the severe pulmonary arterial hypertension group compared to the mild and moderate groups. The more severe the pulmonary arterial hypertension, the worse the heart function. A poorer heart function was associated with a poorer prognosis across different pregnancy outcomes. A pregnancy with more severe pulmonary arterial hypertension and worse cardiac function has a poorer maternal and infant prognosis and pregnancy outcome. Cesarean section is the preferred delivery method for patients with severe pulmonary arterial hypertension, whereas vaginal delivery is preferred for patients with mild or moderate pulmonary arterial hypertension and good cardiac function.
