Migraines Linked To Heart Attack Risk

Friday, February 12th, 2010

According to a new study the incidence of heart attacks in people with migraine is almost double that of people who don’t suffer the headaches.  Researchers note that the exact reason why the two conditions are linked is still unclear.

The report in this week’s online edition of Neurology compared 6,102 people with migraine and 5,243 without the headaches.  The research found a 4.1 percent incidence of heart attacks in the migraine patients, compared with 1.9 percent in those without the debilitating headaches.

Previous studies have found an association between migraine and cardiovascular problems including heart problems and stroke according to the American Association for Critical Illness Insurance, an educational organization that tracks heart disease and cancer information. One study, which looked at only women, found an increased incidence of stroke, especially for migraine with the visual disturbances called aura (women are up to four times more likely than men to have migraines). Another study, which looked only at men, found an increased risk of heart disease.

The new study did find a higher incidence of heart attack for migraine with aura — three times that of the migraine-free group. It also found that people with migraine were more likely to have the classic risk factors for heart attack, stroke and other cardiovascular problems: diabetes (12.6 percent versus 9.4 percent), high blood pressure (33.1 percent versus 27.5 percent) and high cholesterol (32.7 percent versus 25.6 percent). 

Cardiovascular risk reduction is important for everybody. If you have migraine, it might be more important for you than for the general population. They should be particularly vigilant about controlling body weight, keeping blood pressure low, modifying all the risk factors that are within their control. 

The majority of people who have migraines are women, often young women according to some medical experts. This is a marker that might help prevent cardiac disease. There have been several large population studies that show women with migraines have an increased risk of cardiovascular events. These are the women we should be intervening with. If they use oral contraceptives there should be a concern, because they can form blood clots, particularly if they smoke.
