The management of hypertensive disease in pregnancy is currently guided by practice recommendations based largely on observational data from a half century ago and has changed only superficially since that time. These recommendations are both narrowly prescriptive (women without traditional features of severe disease should all be delivered at exactly 37 weeks and 0 days,) and at the same time frustratingly ambiguous (the presence of epigastric pain unresponsive to repeat analgesics precludes expectant management at any gestational age, regardless of laboratory studies.) Guidelines which ignore recent data from the obstetric, pediatric and internal medicine literature too often lead practitioners to be more aggressive than necessary in the delivery of very premature pregnancies, and, conversely, more complacent than patient safety would support in prolonging pregnancy with advanced fetal maturity. We present here an alternative, organ-specific based approach to the management of gestational hypertension which allows and encourages practitioners to formulate a management plan based on a thoughtful and, when possible, evidence- based synthesis of the continuous variables of blood pressure, degree of organ dysfunction and response to treatment, gestational age, and patient balancing of maternal and fetal/neonatal risks. Such clinical care is more complex and nuanced than simply basing life-altering critical management decisions, including timing of delivery, on whether the patient does, or does not have any one of the conditions described by box 4 of the current American College of Obstetricians and Gynecologists practice guidelines. Nonetheless, we believe this approach will not only improve care but will also open the door to useful investigations into prevention and management of the various entities traditionally considered as the same disease process.
