ABSTRACT
There are a paucity of data regarding the role of gender and atrial fibrillation (AF) on cognitive decline and incidence of dementia. Such data may provide insight into the disproportionate incidence of dementia in women and may help identify high-risk characteristics to target for prevention. We examined patients who underwent coronary angiography at an Intermountain Healthcare Medical Center and enrolled in a prospective cardiovascular database. To be included, patients could not have a previous diagnosis of AF or dementia and had to have 5years of follow-up. Endpoints included incident AF and dementia. Study cohort consisted of 35,608 patients without a previous history of AF or dementia, with 14,377 (40.4%) being woman. Women had lower rates of hypertension, diabetes, coronary artery disease, and prior myocardial infarction, but higher rates of prior stroke. Men had a higher incidence of 5-year and long-term AF. However, women trended toward a higher incidence of 5-year and long-term dementia and stroke compared with men. In all groups of patients with and without AF, prior stroke predicted cognitive decline. In patients without a history of or development of AF, diabetes significantly increased risk of dementia. Women have higher rates of dementia over time than men, driven by higher baseline stroke rates and nontraditional cardiovascular risk factors. The higher dementia rates were in the setting of lower AF rates. However, in both men and women who develop AF, dementia rates are increased and do not show gender-based differences in risk.
