Abstract Purpose of Review Hypertensive disorders of pregnancy (HDP)—gestational hypertension, preeclampsia, and eclampsia—are a leading cause of adverse maternal and perinatal outcomes internationally. Prevention, timely diagnosis, and prompt management can reduce associated morbidity. The purpose of this review is to compare international guidelines pertaining to HDP. Recent Findings Fourteen HDP guidelines were compared relative to guidelines for the United States (US) where the authors practice. Aspirin is universally recommended for high-risk women to reduce preeclampsia risk. Recommended dose and gestational age at initiation vary. Diagnoses of chronic hypertension, gestational hypertension, and preeclampsia in pregnant women are similar, although blood pressure (BP) thresholds for antihypertensive medication initiation and treatment targets vary due to the limitations in high-quality evidence. Summary There are differences among international HDP guidelines related to dose and timing of aspirin initiation, thresholds for antihypertensive medication initiation, and BP targets. However, all guidelines acknowledge the significant morbidity associated with HDP and advocate for timely diagnosis and management to reduce associated morbidity and mortality. More research is needed to understand optimal BP thresholds at which to initiate antihypertensive medication regimens and BP targets in pregnancy. Keywords Chronic hypertension . Eclampsia .

Globally, hypertensive disorders of pregnancy (HDP) are a leading cause of morbidity, mortality, hospitalization, and resource utilization for both mothers and their neonates [1–5]. In developed countries, HDP are often diagnosed at routine prenatal care visits, as many women are asymptomatic at the time of diagnosis. Prenatal care affords the opportunity of preven
