Women With Certain Types Of Migraines Have Higher Risk Of Heart Disease
Women who have migraines with visual problems have increased risk for heart disease, according to a study published on Wednesday in the Journal of the American Medical Association, Long Island Newsday reports. For the study, researchers at the Harvard School of Public Health and Brigham and Women's Hospital analyzed the records of 27,800 women older than age 45 who participated in the Women's Health Initiative. None of the women had heart disease when they entered the study between 1992 and 1995. Researchers focused on the records of 5,125 women who had a history of migraines. According to the study, participants who had migraines with migraine aura had more than twice the normal risk for major cardiovascular events. Migraine aura "is a visual sensation -- like lights flashing or lines zigzagging, with some reports of temporary blindness" -- that often lasts for 20 minutes to one hour before migraines begin, Newsday reports. Women who had migraines without migraine aura did not have an increased risk for major cardiovascular events, the study finds. Lead study author Tobias Kurth said that researchers did not determine the cause of the link between migraine aura and heart disease and that the increased risk was small, with about 18 additional cases of heart disease per 10,000 women with migraine aura. Mark Gudesblatt, a neurologist at South Shore Neurologic Associates, said, "It's an important study because it tells you not to take these things lightly" (Talan, Long Island Newsday, 7/19).
