Preeclampsia Clinical Trial
Official title:
Determining the Risk Elevation After Maternity
Evaluating the long term cardiovascular risks of those mothers who have been diagnosed with preeclampsia in pregnancy.
Preeclampsia is a complication of pregnancy that happens in about 5-7% of all births. It is
diagnosed when a mother has high blood pressure in pregnancy combined with protein in the
urine which is sign that the kidneys are not functioning properly. When a mother has
preeclampsia, the placenta makes abnormal amounts of several important proteins that damage
the lining of the mother's blood vessels. The blood vessel damage that occurs places women at
up to 10 times higher risk of having a heart attack or stroke at a younger age than women who
did not have preeclampsia. It usually takes between 8 and 15 years after preeclampsia is
diagnosed for the first heart attack or stroke to occur.
Unfortunately, this blood vessel damage is usually silent, meaning that women and their
doctors are not aware of it. This makes it hard to predict which women are at highest risk of
a heart attack or stroke and therefore need extra medical care to prevent it. Abnormal levels
of the placenta proteins in the blood (right after delivery and at three and six months after
delivery) as well as abnormalities of the placenta itself may be the earliest way to predict
which women with preeclampsia are at risk of premature heart disease or stroke.
The purpose of this study is to collect blood and placentas from women with preeclampsia and
without preeclampsia to measure and compare the levels of proteins in the blood and find
abnormalities of the placentas that are associated with preeclampsia. We will then see if
these tests can predict which women will go on to develop high blood pressure and ultimately
be at higher risk of premature heart attack or stroke after pregnancy.
