Previous research established an association between CAD and migraine, especially migraine with aura, but new study data suggest that gene variants may not be the cause. In fact, genetic variants shared by migraine without aura and CAD were protective against CVD, researchers reported.
“Surprisingly, when we looked for shared gene variants that might help explain part of the link between migraine and heart disease, we found no shared gene variations between migraine with aura and heart disease,” Aarno Palotie, MD, from Massachusetts General Hospital and the Broad Institute of the Massachusetts Institute of Technology and Harvard University, said in a press release. “This is surprising because the evidence is stronger that people with migraine with aura have an increased risk of heart disease than people with migraine without aura.”
