Migraines linked to heart attack risk (USA)

"People who suffer from migraine headaches may be much more likely to have a heart attack as well as a host of risk factors for heart disease, according to a new study. Although the overall risk was small, researchers found that people who have migraines were twice as likely to have a heart attack, and people who have migraines with aura were nearly three times more likely to have a heart attack, than others. Migraines with aura are preceded by sensations such as seeing flashing lights. The study also shows that people with migraines are more likely to have major risk factors for heart disease, such as high blood pressure, diabetes, and high cholesterol, which may partially explain this increased risk of heart attack. "Our results provide another reason for people with migraine to reduce other risk factors for heart disease, such as high blood pressure and obesity," says researcher Marcelo E. Bigal, MD, PhD, of Merck Research Laboratories and the Albert Einstein College of Medicine in Bronx, N.Y., in a news release. However, even after adjusting for these underlying risk factors for heart disease, researchers found people with migraines were still more likely to have a heart attack, stroke, or evidence of peripheral artery disease (a buildup of plaque in the arteries usually in the legs or arms). The study compared the risk of heart attack, stroke, and other risk factors for heart disease among 6,102 people with migraine headaches and a comparison group of 5,243 people without headaches who were surveyed about their health. The results, published in Neurology, showed that 4.1% people who had migraines had a heart attack compared with 1.9% of the rest. The risk of heart attack was nearly three times greater for people who experienced migraine with aura than for people without migraines" - WebMD
