Hypertension in pregnancy is a frequent complication that
has substantial adverse perinatal outcomes. Hypertension
may be preexisting (chronic) essential or secondary hypertension;
a second entity is pregnancy induced (gestational
hypertension, preeclampsia). Recent advances have identified
newer markers for pregnancy hypertension: several potential
candidate genes may explain the apparent family inheritance
of preeclampsia, and some thrombophilic markers hav
been associated with the condition. Management options
for mild to moderate hypertension include a short hospital
stay to exclude ongoing severe hypertension and to ascertain
fetal well-being. Outpatient care with appropriate materna
and fetal surveillance, including umbilical artery dopple
velocimetry, is recommended for better perinatal outcomes.
Acute care for severe hypertension includes the use of
magnesium sulfate to prevent eclampsia and antihypertensiv
medication. Expeditious delivery is recommended when
the maternal or fetal states cannot be stabilized. Follow-up
after delivery allows the uncovering of any other coexisting
hypertensive or cardiovascular disorder.
