ClinicalTrials.gov Identifier: | NCT00759278 |
This is a prospective case-control study to evaluate women who are pregnant and take antihypertensive medication for fetal hemodynamics (middle cerebral artery peak systolic flow and umbilical artery Doppler systolic to diastolic ratio) compared to a control group of pregnant women not taking these kinds of medications. The hypothesis is that the investigators expect to observe little to no difference in the comparison between the medication group and the control group.

1
Group of 30 women who are pregnant as subjects that take antihypertensive medication
|
Procedure: ultrasound evaluation in pregnancy
Subjects enrolled will have a series of ultrasound evaluations to assess parameters in the study. Ultrasound is a non-invasive technique for creating images that does not use radiation and is routine in obstetrical practice
