Men's Migraines Up Heart Attack Risk
Study Shows Middle-Aged Men Who Have Migraines More Likely to Have Heart Attacks

Nov. 15, 2006 -- Middle-aged men who suffer from migraine headaches are 42%
more likely to have a heart attack when compared with nonsufferers, according
to a new analysis of the 20,084 men participating in the Physicians' Health
"Until we understand more about the association between migraines and
disease, patients with migraines should think about how to mitigate
other known heart disease risk factors such as high blood
pressure, diabetes, high
cholesterol levels, smoking, and obesity," says
researcher Tobias Kurth, MD, assistant professor of medicine at Brigham and
Women's Hospital and Harvard Medical School.
The study comes on the heels of other research by Kurth and colleagues that
showed that older women with migraines -- especially those accompanied by
neurologic visual disturbances known as aura -- had a higher risk of heart
attacks and cardiovascular disease.
In the current study, the researchers did not have information on whether
the men had auras. But Kurth says he believes the "findings in women are
probably generalizable to men."
An aura occurs before the onset of a migraine. Aura symptoms can include,
but are not limited to, light flashes, blind spots, blurred vision, and the
formation of dazzling zigzag lines during the migraine. Aura can also include
changes in sensation and smell.
About one-third to one-fifth of sufferers of either sex typically have aura
As in the women's study, it is not clear if the heart risks apply to younger
people, as they were not studied.

The study, presented at the American Heart Association's Scientific Sessions
2006, included 20,084 men participating in the Physicians' Health Study.
The men were aged 56 on average when they joined the study, and none had a
history of cardiovascular disease or angina at the start of the
study. They were followed for an average of 15.7 years.
Of the total, 1,449 (7.2%) men were classified as being migraine sufferers,
having reported they suffered them during the first five years of the
At the start of the study, men with migraines were slightly more likely to
have high blood pressure or elevated cholesterol levels, compared with men who
didn't have migraines. But even after these factors were taken into account,
there was still a significant association between migraines and heart
