Scientists from the Duke University, Durham, North Carolina found a link between migraine headaches in pregnancy and vascular events such as heart attacks and strokes.

They reported that women with persistent migraine during pregnancy should be aware of their risk factors that include high blood pressure, high cholesterol, diabetes, history of blood clots, heart disease, and stroke. They also found a link between pregnancy migraines and preeclampsia, which is the most common and dangerous complication of pregnancy.

From 17 million women with a pregnancy-related discharge from US hospitals around 34,000 were treated for migraine during their pregnancy. Women over 35 were more likely to have migraines than younger women.
Women with migraines during pregnancy were found to be 19 times more likely to suffer a stroke, five times more likely to suffer a heart attack and more than twice as likely to have heart disease, blood clots and other vascular problems. They were also more likely to develop preeclampsia or high blood pressure during their pregnancy.

Disorders that represent risk factors for vascular disease such as diabetes, high blood pressure and smoking have been linked to experiencing migraine headache during pregnancy. Earlier research showed a connection between stroke and cardiovascular disease in older women and the new one included pregnant women as well.
