Assessing progression from mild to severe preeclampsia in expectantly managed preterm parturients

Highlights • Systolic blood pressure > 160 mmHg on admission was associated with a three-fold increased risk for delivery within seven days of diagnosis. • Among subjects with latency greater than seven days, mean latency was prolonged by greater than three weeks. • There may exist a subset of subjects in whom expectant management of preeclampsia without severe features remote from term may be feasible.
