Abstract

Background Sudden cardiac death (SCD) mortality is on the decline in the United States. This study explores SCD trends from 1999 to 2020, using age-adjusted mortality rates (AAMR) to identify disparities within specific epidemiological groups. Methods We analyzed SCD mortality trends using the Centers for Disease Control and Prevention's Wide-Ranging Online Data for Epidemiological Research database. AAMR per 100,000 people and annual percent changes (APC) with 95% confidence intervals were calculated. Joinpoint regression analysis was used to assess overall trends and variations among key demographic (gender, race, age, urban/rural), and regional groups. Results Between 1999 and 2020, 281,330 sudden cardiac deaths were reported. The overall AAMR for SCD decreased from 4.5 in 1999 to 3.6 in 2020. Higher mortality rates were observed in males, African Americans, individuals over 85 years old and residents of nonmetropolitan areas. From 1999 to 2018, the AAMR decreased significantly with an annual percent change (APC) of -1.92. However, an increase occurred between 2018 (AAMR 3.1) and 2020 (AAMR 3.6) with an APC of 4.16. Conclusion Over the past two decades, SCD mortality has declined in the United States, but recent data suggests a concerning upturn. Persistent demographic and geographic disparities in SCD mortality underscore the need for further investigation and intervention. [Formula presented]
