Early Pregnancy Systolic Blood Pressure Patterns Predict Early‐ and Later‐Onset Preeclampsia and Gestational Hypertension Among Ostensibly Low‐to‐Moderate Risk Groups

Background Clinical risk factors, a single blood pressure (BP) measurement, current biomarkers, and biophysical parameters can effectively identify risk of early‐onset preeclampsia but have limited ability to predict later‐onset preeclampsia and gestational hypertension. Clinical BP patterns hold promise to improve early risk stratification for hypertensive disorders of pregnancy. Methods and Results After excluding preexisting hypertension, heart, kidney, or liver disease, or prior preeclampsia, the retrospective cohort (n=249 892) all had systolic BP
