People who suffer from a migraine may be at an increased risk of developing cardiovascular diseases including heart attacks, stroke, blood clot and an irregular heart rate, researchers say.<\/p>\n
Around one billion people worldwide are affected by a migraine. It has a considerable impact on quality of life and imposes a substantial burden on society.<\/p>\n
Although the absolute risks were low, the findings suggest that \u201ca migraine should be considered a potent and persistent risk factor for most cardiovascular diseases in both men and women\u201d, said researchers from Aarhus University Hospital, Denmark and Stanford University, US.<\/p>\n
Migraine\u2019s association with cardiovascular disease risk can be attributed to the increased use of anti-inflammatory drugs, by the patients suffering from the headache disorder.<\/p>\n
Anti-inflammatory drugs are associated with increased risks of heart problems, while immobilisation related to migraine attacks may be behind the increase in the risk of blood clot.<\/p>\n
Current guidelines do not recommend the use of anti-clotting drugs such as aspirin to treat a migraine, but clinicians need to \u201cconsider whether patients at particularly high risk of heart disease would benefit from anticoagulant treatment\u201d, the researchers said, in a paper published in the journal The BMJ.<\/p>\n
For the study, the team compared data from over 51,000 Danish people who had been diagnosed with a migraine with over 510,000 Danes who were a migraine-free over a 19 year period, from 1995 to 2013.<\/p>\n
While a link between a migraine, stroke and heart attacks, have been previously established, the new study showed that a migraine also was positively associated with a blood clot and irregular heart rate.<\/p>\n
For example, for every 1,000 patients, 25 patients with a migraine had a heart attack compared with 17 a migraine-free patient while 45 patients with a migraine had an ischaemic stroke (blood clot in the brain) compared with 25 a migraine free patients, the study showed.<\/p>\n","protected":false},"excerpt":{"rendered":"
