masses who experiencemigrainesmay be more probable to develop cardiovascular problem , a new study from Denmark finds .
These headaches were affiliate with an increased risk for several heart problem , including centre attack , stroke , atrial fibrillation ( a type of temporary heart rhythm ) and blood coagulum that get in a person ’s veins , according to the study , which was published today ( Jan. 31 ) in the journalThe BMJ .
sick headache are primarily considered a headache upset ( as oppose to a center issue ) , with symptoms such as an acute pulsing or pounding infliction , sickness , and sensibility to light and sound . However , this is not the first study to link up migraine cephalalgia and spunk problems , said written report lead author Dr. Kasper Adelborg , a cardiologist at Aarhus University Hospital in Denmark . former studies have suggest a link betweenmigraines and the risk of throw and heart attack , particularly among cleaning woman , he said .
The new study confirmed this link and also found that megrim were associated with an increase danger of other bosom problems , such as stock clots and atrial fibrillation , Adelborg told Live Science . In addition , because the new analysis admit a bombastic number of people , the determination can provide research worker with clues about how migraines strike cardiovascular problems at a universe level , Adelborg said .

In the study , the researchers looked at information from about 51,000 people in Denmark who had migraines and about 510,000 masses who did not . People in the migraine group had been first diagnose by age 35 , on average , and 71 pct of them were women , according to the findings .
After 19 year of follow - up , the field determined that people with migraines had a 1.5 - fold increased risk of heart attack and a treble increasedrisk of stroke , compared with mass who did not have the headache , Adelborg read . The work also find that for people with migraines , the risk of blood clots was 1.6 clip bully and the risk of atrial fibrillation was 1.3 times groovy , compared with people who were migraine - free .
In addition , researcher found that the association between sick headache and several of the cardiovascular problems were substantial in women than in man . The association was also stronger in people who hadmigraines with an " aura,“a phenomonen that can precede the concern and that let in visual disturbances such as seeing flash lights or take blind smear in one eye .
The head-heart connection?
There are several ground why megrim may be link to cardiovascular problem , the researcher said . One potential mechanics may involve the sudden constriction ofblood vessels in the brainthat is consider to lead to migraines ; this may also make a person more vulnerable to stroke , Adelborg said . ( When blood vessels suddenly constrict , it is more hard for blood to flow , which could lead to a lack of blood in parts of the encephalon . )
Another possible explanation may be that masses who have hemicrania are less alive and need to repose when installment strike , which could increase the risk of blood clots , he said .
Though the exact mechanisms for the connection continue indecipherable , a mounting body of evidence supports considering megrim to be strong and persistent risk factors for mostcardiovascular diseasesin both men and charwoman , Adelborg said . Although the risk of nitty-gritty problem among people with migraines in the study was low at an individual level , this still translates into a substantial increase in heart disease risk of exposure at a population level , because migraine is a very common condition , he said .
One limit of the inquiry is that the average eld of the field of study population was 35 , which is young for heart - link up problems , even though the conform to - up period last nearly two decades , Adelborg state . Future research will need to find whetherprevention strategies for migrainescan also reduce the risk of cardiovascular disease , he say .
