1387-P: Risk of Perinatal Complications across Gestational Blood Pressure Levels in Women with and without Gestational Diabetes (GDM)

Hypertensive disorders in pregnancy and GDM are among the leading causes of maternal and perinatal morbidity. In 2017, the American College of Cardiology/American Heart Association released a new guideline for hypertension: systolic/diastolic blood pressure (SBP/DBP) ≥130/80 vs. previous 140/90 mmHg. However, these new cut-points have not been applied to pregnant women due to the lack of evidence on its impact on perinatal outcomes. We examined in women with and without GDM whether the risk of perinatal complications increased across SBP/DBP levels: normal ( Disclosure Y. Zhu: None. J. Feng: None. A. Ngo: None. C.
