High Blood Pressure During Pregnancy Tied to Later Heart Trouble11/28/12
TUESDAY, Nov. 27 (HealthDay News) -- Single-child mothers who
develop preeclampsia during their pregnancy are more likely to die
from heart disease later in life than mothers with multiple
children who developed the blood pressure condition during their
first pregnancy, a large, new study suggests.
The study was published online Nov. 27 in the journal
This is the first time that this increased risk among
single-child mothers has been reported and suggests that these
women require special monitoring, according to a journal news
Preeclampsia is a serious condition in which high blood pressure
and protein in the mother's urine develop in the second half of
Researchers looked at data from more than 836,000 Norwegian
women who gave birth to their first child between 1967 and 2009. By
2009, nearly 3,900 of the women had died from heart disease.
Overall, women with preeclampsia in their first pregnancy had a
higher risk of heart-disease-related death than women who did not
have preeclampsia. But the risk was up to nine times higher among
women who had one child, compared with 2.4 times higher among those
who had more children.
The vast majority of women with preeclampsia can expect a normal
lifespan, according to Rolv Skjaerven, a professor at the
University of Bergen in Norway, and colleagues.
Although current guidelines say all women with preeclampsia are
candidates for special monitoring, these findings suggest that
further consideration should be given to single-child mothers, the
Women may only have a single child because of underlying health
problems such as diabetes -- that discourage or prevent further
pregnancies rather than due to preeclampsia itself, the authors
Although the study found an association among preeclampsia,
having one child and maternal death from heart disease, it did not
prove a cause-and-effect relationship.
