Women with heart rhythm disorder experience faster cognitive decline compared to men

Women with atrial fibrillation were three times more likely to have mild cognitive impairment or MCI and dementia at baseline compared to women without atrial fibrillation. During a median follow-up of four years, 30% of participants progressed to a worse stage of cognitive impairment and 21% developed dementia. Women with atrial fibrillation had a higher risk of progressing to a worse stage of cognitive impairment compared to women without atrial fibrillation. Regarding progression to each stage, compared to women without atrial fibrillation, women with the condition were more likely to transition from normal cognition to MCI and from MCI to vascular dementia. The associations between atrial fibrillation and more rapid cognition decline were not statistically significant in men.
