A new study published in the online journal of Neurology found that high blood pressure, particularly high diastolic blood pressure, was associated with a slightly higher likelihood of ever having migraines in women. Diastolic pressure occurs when the heart relaxes between beats. However, the study did not find an increased risk between other cardiovascular risk factors and migraine.
“Previous research shows that migraine is linked to a higher risk of cardiovascular events such as stroke, heart disease and myocardial infarction (heart attack), but less is known about how the risk factors for cardiovascular events are linked to migrate,” study author Antoinette. Maassen van den Brink, from the Erasmus Medical Center at the University of Rotterdam, the Netherlands, said in a press release from the American Academy of Neurology (AAN). News.ro.
The study looked at known risk factors for cardiovascular disease, such as diabetes, smoking, obesity and high cholesterol, and found that migraine was only more likely in female participants with high blood pressure higher diastolic.
The study included 7,266 men and women with an average age of 67, and 15% were migrants.
All participants were physically examined and provided blood samples. They were also asked questions about migraine, including whether they had ever had a headache with severe pain that affected their daily activities.
After adjusting for several cardiovascular risk factors, such as physical activity as well as education level, the researchers found that female participants with higher diastolic blood pressure were 16% more likely to have migraines on a standard deviation increase in diastolic blood pressure.
Elevation per standard deviation is a measure to compare diastolic blood pressure with other cardiovascular risk factors.
No association was found for systolic blood pressure.
Experts say that this adds to the theory that migraine is related to the work of a little less small blood vessels rather than the work of less large blood vessels.
There was no association for female participants with high cholesterol or obesity, and current smoking was associated with a 28% less chance of migraine and diabetes with a 26% less chance of migraine.
“These results should be interpreted with caution, as they do not prove that smoking causes a lower risk of migraine. On the other hand, smoking may trigger migraine attacks, so people who choose to smoke are less likely to suffer from migraines,” said Maassen van den Brink.
For male participants, the researchers found no association between cardiovascular risk factors and migraine.
“Our study suggests that, in general, migraine is not directly related to traditional risk factors for cardiovascular disease,” concluded Maassen van den Brink.
“Because we looked at people who were middle-aged and older, future studies are needed in younger groups of people who are followed for longer periods of time,” she said.
A limitation of the study was the small number of male participants with migraine. Maassen van den Brink said this may explain why an association between cardiovascular risk factors and migraine was not identified for male participants.
