Abstract

Background: Hypertensive disorders of pregnancy complicate up to 10% of pregnancies and represent a significant cause of maternal and perinatal morbidity and mortality. The aim of this study was to evaluate blood pressure (BP) variability and right ventricular (RV) remodeling in women with gestational HTN (GH) and PE, as well as their association. Methods: This observational comparative study included 40 female patients with pregnancy-related hypertensive disorders (Group A) and 20 healthy pregnant women as a control group (Group B) at Aswan University hospital. Results: At three-month follow-up, systolic/diastolic BP, RV dimensions, and RV strain remained significantly higher in the cases group, whereas SD of systolic BP and S' were lower (P<0.05). RV structure and function were similar between preeclampsia and gestational hypertension groups, except for higher RAVI, global RV, and free wall RV strain in preeclampsia (P<0.05). Maternal and fetal complications showed no significant difference between groups.
Conclusions: BP variability significantly impacts RV remodeling in pregnant women with GH and PE. Despite similar maternal and fetal complication rates between groups, the persistence of elevated BP and RV abnormalities postpartum underscores the need for ongoing cardiovascular monitoring and management.
