Migraines increase risk of heart attack, says study
Zee Media Bureau
Berlin: Scientists have found that women who suffer from migraines have higher risk of developing cardiovascular diseases. The new study has claimed that such people are more prone to die from these conditions than people who do not have migraine.
Researchers of the study said that the findings add to evidence that migraines should be considered an important risk marker for heart attack and stroke.
Though few studies have shown an association of migraine with cardiovascular diseases and mortality, but it has been consistently linked with an increased risk of heart disease.
A large prospective study has been carried out by the researchers from Institute of Public Health in Germany and Harvard T H Chan School of Public Health in the US to evaluate associations between migraine, cardiovascular disease and mortality.
The findings analysed data from 115,541 women. The participants were aged 25-42 years, free from angina and cardiovascular disease, and followed from 1989-2011 for cardiovascular events, diseases and mortality.
Overall, 17,531 (15.2 per cent) women reported a physician's diagnosis of migraine at baseline. Over 20 years of follow-up, 1,329 total cardiovascular disease events occurred and 223 women died due to cardiovascular disease, researchers said.
When compared to women who did not have migraines, these results show that women who reported a migraine had a greater risk for major cardiovascular disease, including heart attacks, strokes and angina/coronary revascularisation procedures, they said.
These associations remained after adjusting for other factors that may have increased the risk for these diseases.
Migraine was associated with a higher risk for cardiovascular mortality. This association was similar across subgroups of women, including by age, smoking status, hypertension, postmenopausal hormone therapy, and oral contraceptive use, researchers said.
"These results further add to the evidence that migraine should be considered an important risk marker for cardiovascular disease, at least in women. There is no reason why the findings cannot be applicable to men," they said.
The findings were published in the BMJ.
