Abstract 4146016: Trend-Analysis of Atrial Fibrillation and Atrial Flutter Related Mortality from 1999 to 2022: A CDC-Wonder Database Study

Introduction: Atrial Fibrillation is the most common arrhythmia, causing an irregular and rapid heart rate. This occurs due to electric and structural remodeling of the atria, which creates the rapidly discharging foci. Aims: This study aims to explore the national mortality trends resulting from Atrial Fibrillation and Flutter in the United States from 1999-2022 while also studying the discrepancies among the various socio- demographic groups. Methods: The death certificate data from the Centers for Disease Control and Prevention’s Wide-Ranging Online Data for Epidemiological Research (CDC Wonder) database were explored to investigate the Atrial fibrillation and flutter mortality from 1999 to 2022, focusing on the Age-Adjusted Mortality Rate (AAMR) per 1,000,000 individuals. We employed Joinpoint Regression Analysis to compute Annual Percent Changes (APC) with a 95% Confidence Interval. The data was further stratified into epidemiological groups of age, gender, ethnicity, and census region. Results: There was a steady rise in mortality from 1999 to 2017 (APC: 2.96), followed by a rapid surge in mortality trends from 2017 to 2022 (APC: 7.35). The mortality rate rose fairly equally among both genders over the years, with males having a slightly steeper incline (Male AAPC: 4.27, Female AAPC: 3.43). African Americans had the greatest number of deaths due to atrial fibrillation and flutter and the greatest rise was during recent years from 2017 to 2022 (APC: 9.64). The atrial fibrillation and flutter related mortality was the greatest among 25-34-year-olds, with the mortality decreasing among the older populations. All US Census regions had similar mortality rates and trends. Conclusion: This study reveals an overall rise in mortality associated with atrial fibrillation and flutter. It also highlighted disparities across gender, age, and geographic regions. These findings emphasize the need for further research and the development of targeted interventions to reduce mortality and alleviate the burden of this debilitating condition.
