Abstract 12877: National Trends of Atrial Fibrillation/Atrial Flutter Mortality in the United States From 1999 to 2019: Regional, Racial, and Gender Variations

Abstract

Introduction: There is an emerging need to evaluate Atrial Fibrillation/Atrial Flutter (AF/AFL) mortality trends in different races and genders in different regions across the US. Methods: In an observational study utilizing the CDC WONDER database, age-adjusted mortality rates (AAMR) per 100,000 people for AF/AFL between 1999 and 2019 were investigated. Trends in AAMR were determined by evaluating average annual percentage changes (AAPC)s with Joinpoint regression analysis. Results: In the total US population from 1999 to 2019, AAMR due to AF/AFL has increased from 3.1 to 6.5 per 100,000 population. AF/AFL-related mortality rates have nearly doubled in all racial groups, ranging from an 84% increase in Black males (2.5 to 4.6 per 100,000) to a 123% increase in White males (3.1 to 6.9 per 100,000). AF/AFL-related mortality relative increase was highest in the West (140%) followed by Midwest (124%) and South (103%) while North East (81%) came last. Comparing white race mortality rates in different census regions, West demonstrated the highest increase in AAMR in the white population [170% in males, 138% in females]. Meanwhile, Midwest had the highest increase in the Black/African American population with a 111% increase in Females and 130% increase in Males. The Northeast showed the least increase in AAMR in both blacks and whites. Joinpoint analysis demonstrated that AF/AFL-related mortality rate has plateaued for black females and white males since 2017; the same plateau occurrence can be seen for white females since 2015 (Figure 1). Conclusion: The greatest increases in mortality occurred among white men and women and in Western states. AAMR increase has plateaued recently in white males as well as black and white females. AAPCs demonstrate that the rates of increases in AF mortality are greatest in Caucasians, followed by Asian and Black Americans.
