Women with severe migraine with aura have a higher risk for atrial fibrillation


Key clinical point: Severe migraine without aura increased the long-term risk for atrial fibrillation (AF) by 16%-21% in both men and women. The risk for future AF was highest in women with severe migraine with aura but not significant in male counterparts.

Major finding: Men (adjusted hazard ratio [aHR] 1.21; 95% CI 1.12-1.31) and women (aHR 1.16; 95% CI 1.09-1.22) with severe migraine without aura had a modest but significantly higher risk for AF. The risk was most prominent in women with severe migraine with aura (aHR 1.48; 95% CI 1.18-1.85), but was not significant in men.

Study details: Findings are from a large-scale population-based study including 4,020,488 participants without AF, of which 4986 and 105,029 had migraine with and without aura, respectively.

Disclosures: This study was supported by a Korea Medical Device Development Fund grant funded by the Korea Government. E-K Choi and GYH Lip reported receiving research grants or speaking fees or serving as consultants or speakers for various sources.
