HealthDay News — Several factors raise the risk of pregnancy-related stroke in women with preeclampsia, according to a study published online in Stroke.

Researchers looked at data for 88,857 women who developed preeclampsia between 2003 and 2012. Of those, 197 had a pregnancy-related stroke.

The researchers found that women who had a pregnancy-related stroke were 7 times more likely to have severe preeclampsia or eclampsia (odds ratio [OR]: 7.2). They were also 3 times more likely to arrive at the hospital with infections (OR: 3.0), chronic hypertension (OR: 3.2), prothrombotic states (OR: 3.5), and coagulopathies (OR: 3.1).

“Preeclampsia is a very common disorder, and a lot of people are not aware of its association with stroke,” lead author Eliza Miller, MD, of the New York-Presbyterian Hospital/Columbia University Medical Center in New York City, said in a journal news release. “Women with preeclampsia should take any neurological symptoms, such as severe headache, very seriously, especially during the postpartum period. This needs to be a major focus of future stroke research in women.”
