Some men with migraine are at increased AF risk

Autonomic dysfunction may be the cause

Migraine with visual aura is associated with an increased risk of developing atrial fibrillation (AF), according to results from the Atherosclerosis Risk in Communities (ARIC) study.

"Migraine with visual aura (MA) has been associated with an increased risk of stroke, specifically cardioembolic ischemic stroke," said Dr Souvik Sen of the University of South Carolina School of Medicine, in Columbia.

"Among various pathophysiological mechanisms postulated for the association between MA and incident AF, autonomic dysfunction among the population with MA may play a key role. This association has not been studied in any large cohort study," he said by email.

Dr Sen and colleagues used ARIC data from more than 1,500 patients with migraine 426 of whom had MA and more than 9,400 patients without headache to evaluate the potential association between migraine with visual aura and incident AF.
