Pregnancy outcomes among patients with stage 1 chronic hypertension.

ABSTRACT

In recent years, the American College of Cardiology and the American Heart Association have reduced the thresholds for a hypertension diagnosis among nonpregnant adults. This change has led to more individuals with reproductive potential to be labeled as being chronically hypertensive, and some were started on antihypertensive medications. When these individuals become pregnant, the obstetrical care provider will have to decide whether to manage them as individuals with chronic hypertensive when only a few years ago they would have been managed as normotensive individuals and when the evidence regarding treatment of these patients during pregnancy is limited. If implemented widely, the management of patients with stage 1 hypertension similar to the traditional chronic hypertension will likely lead to additional maternal and fetal testing, to an increase in hospital admissions, and potentially to unnecessary interventions, such as preterm birth. Our goal was to compile the existing evidence regarding the pregnancy outcomes among patients with stage 1 hypertension to assist providers in their diagnosis and management of this patient group.
