High blood pressure during pregnancy could dramatically raise a woman’s lifetime risk of stroke, according to a study presented today at the Canadian Stroke Congress.
“We’ve found that women who had high blood pressure during pregnancy could be at higher risk of stroke, particularly if they had pre-eclampsia, which is a more severe form of high blood pressure,” says Dr. Aravind Ganesh, a neurology resident at the University of Calgary. “The elevated risk of stroke could be as high as 40 per cent.”
Dr. Ganesh, along with Neha Sarna (medical student), Dr. Rahul Mehta (internal medicine resident) and senior author Dr. Eric Smith (stroke neurologist), conducted a systematic review — basically, a study of studies.
Nine studies specifically looked at hypertension (high blood pressure) during pregnancy and its relationship to future risk of stroke.
The studies followed women for anywhere from one to 32 years after a pregnancy, and found consistent evidence that those with a history of hypertension in pregnancy are more likely to experience stroke in later life.
