AB Hypertensive  disorders  seriously  complicate  approximately  2%  to  8%  of  all  pregnancies.1  Indeed,  19%  of  pregnancy-related  maternal  mortality  is  due  to  complications  related  to  hypertensive  disorders.2  Hypertensive  disorders  during  pregnancy  involve  a  variety  of  clinical  entities,  including  gestational  hypertension,  preeclampsia,  eclampsia,  chronic  hypertension,  superimposed  preeclampsia  on  chronic  hypertension,  and  hemolysis,  elevated  liver  enzymes,  low  platelets  (HELLP)  syndrome.3  The  normal  physiologic  changes  of  pregnancy  result  in  a  net  reduction  of  systolic,  diastolic,  and  mean  arterial  blood  pressure  by  midpregnancy  because  of  decreased  systemic  vascular  resistance  and  the  presence  of  a  low  resistance  to  flow  placenta.  At  the  end  of  term  pregnancy,  the  blood  pressure  returns  to  baseline  prepregnant  level.4
