Abstract Background Ventricular arrhythmias (VAs) are a proximate mechanism of sudden cardiac death, yet national patterns in place of death (POD) and their determinants remain sparsely described. We quantified 25-year trends and factors associated with POD among UAs decedents in the United States. Methods We analyzed CDC WONDER Multiple Cause of Death data (1999–2024) for adults ≥25 years with ventricular arrhythmias (ICD-10 I47.2, I49.0) as underlying cause. POD was categorized as inpatient, outpatient/emergency department (ED), home, hospice/nursing, or other/unknown. Covariates included age, sex, race, Hispanic origin, and urbanization. We calculated Annual and Average Annual Percent Changes (AAPCs and APC) using Age-Adjusted Mortality Rates (AAMRs), and fit multinomial logistic regression (reference = inpatient) to obtain adjusted odds ratios (ORs, 95% CIs). Results Among 433,988 ventricular arrhythmia (VA) deaths, POD was inpatient 62.0%, outpatient/ED 18.1%, home 11.1%, hospice/nursing 5.8%, other 3.1%. Inpatient deaths increased from 57.8% (1999) to 66.1% (2024). AAMRs declined sharply from 13.3 per 100,000 in 1999 to 6.3–6.5 during 2010–2019, then rose to 7.4 in 2021 and fell to 6.8 in 2024. In home vs inpatient: ≥85 years, medium/small metropolitan counties and rural counties had higher odds of VA deaths, whereas younger age groups, females, Black, American Indian, Asian/Pacific Islander individuals and Hispanic individuals had lower odds. In outpatient/ED vs inpatient: 25–44 years, 45–64 years, males, Black, American Indian and Asian/Pacific Islander individuals had higher odds, whereas ≥85 years and females had lower odds. In hospice/nursing facilities: ≥85 years, females, Whites, non-Hispanic individuals, medium/small metropolitan counties and rural counties had higher odds of VA deaths, whereas younger age groups, Black, American Indian, Asian/Pacific Islander individuals and Hispanic individuals had markedly lower odds. Conclusion From 1999–2024, VA deaths shifted toward hospitals. Persistent disparities by age, sex, race/ethnicity, and rurality highlight the need to expand equitable advance care planning and device deactivation discussions.

ABSTRACT Background Atrial fibrillation (AF) is a prevalent arrhythmia that frequently coexists with cardiomyopathy, leading to deteriorated cardiovascular outcomes. Analyzing the trends associated with these conditions is essential for improving prevention strategies and management practices. Methods CDC WONDER (1999–2023) data were analyzed to assess AF with cardiomyopathy‐related mortality in patients aged ≥ 25. Using Joinpoint regression analysis, we calculated age‐adjusted mortality rates (AAMRs) per 100,000 patients and average annual percentage changes (AAPCs) to analyze mortality trends. Results AF with cardiomyopathy is responsible for 126,377 deaths among adults aged 25 and older. Alarmingly, AAMRs have surged from 1.8 per 100,000 in 1999 to 3.0 in 2023 (AAPC: 2.11, p < 0.001). The upward trend remains pronounced, particularly between 2016 and 2021, with an annual percentage change of 6.17 ( p = 0.02). Disparities in mortality rates are striking. Men face a higher AAMR than women (3.1 vs. 1.5), and Black individuals bear the heaviest burden at 2.4, closely followed by Whites at 2.3. Regionally, Vermont stands out with the highest AAMR at 3.6, while New York reports the lowest at 1.3. Both rural and urban areas maintain equal AAMRs of 2.1, yet the increase in rural regions is particularly concerning, reflecting an AAPC of 2.44 compared to 1.78 in urban settings. Conclusion The rising mortality rates from AF with cardiomyopathy in patients, particularly among men, Black individuals, and rural residents, demand urgent action. These concerning trends underscore a public health crisis that must be addressed.
