Regional and Demographic Disparities in Atrial Fibrillation Mortality in the USA.

Background: Despite the burden of atrial fibrillation/flutter (AF/AFL) in the USA, an assessment of contemporary mortality trends is scarce in the literature. This study aimed to assess the temporal trends in AF/AFL deaths among US adults by age, sex, race/ethnicity, and census region from 1999 to 2020.

Methods: National mortality data was abstracted from the National Center for Health Statistics to identify decedents whose underlying cause of death was cardiovascular disease and multiple cause of death, AF/AFL.
