Over the course of the study, the 1,500 men with migraines had a combined total of 2,236 major cardiovascular events, including heart attack and stroke. In fact, these men were found to have a 42 percent increased risk of having a heart attack than the men without migraines.
Kurth’s previous study found that women who had migraines with an aura also had this increased risk of heart attack. An aura is a sensation of flashing lights, blurry vision or blind spots that may precede or appear along with a migraine. While the men in this study were not asked about aura symptoms, Kurth believes this link may hold true for his current study as well.
“Since this migraine and cardiovascular disease association was only apparent from migraine with aura in women,” said Kurth, “this difference may be explained by the missing information on migraine aura in men.”
It is unclear why a migraine may increase one’s risk of cardiovascular disease, but Kurth believes that migraine may increase the risk of blood clots or particular levels of an amino acid that are both linked to heart disease risk.
“Further research is needed to understand why migraine is associated with cardiovascular disease before potential preventative strategies can be developed,” said Kurth.
People who suffer from migraines, therefore, should speak with their doctors about ways they can lower their risk of heart disease. This may include improving diet to lower cholesterol levels, taking medicines to lower blood pressure, exercise and eliminating smoking.
