Abstract Background While cardiac implantable electronic devices (CIED) are increasingly used, real-world data on the mortality rate due to mechanical complications of CIED is scarce. Objective This study aimed to determine longitudinal trends in mortality attributed to mechanical complications of CIED. Methods We queried the Centers for Disease Control and Prevention’s Wide-Ranging Online Data for Epidemiologic Research and performed serial cross-sectional analyses of national death certificate data for mechanical complications of CIED-related mortality among the United States population aged ≥ 35 years from 1999 to 2020. Cardiovascular disease (ICD-10: I00–I99) was listed as the underlying cause of death, and mechanical complication of the cardiac electronic device (ICD-10: T82.1) was stated as the contributing cause of death. We calculated age-adjusted mortality rates (AAMRs) per 1,000,000 individuals. Linear regression was used to calculate for the significance of the annual percent of changes in AAMRs. Results 1237 cardiovascular deaths related to mechanical complications of CIED were identified between 1999 and 2020. The AAMR dropped significantly from 0.45 per 1,000,000 individuals in 1999 to 0.21 per 1,000,000 individuals in 2020 (p < 0.01). Cumulative AAMRs were higher in males than females (0.39 per 1,000,000 individuals vs. 0.26 per 1,000,000 individuals, p < 0.01), higher in White populations than African American populations (0.32 per 1,000,000 individuals vs. 0.30 per 1,000,000 individuals, p < 0.01), and higher in the rural areas than in the urban areas (0.50 per 1,000,000 individuals vs. 0.27 per 1,000,000 individuals, p < 0.01). Conclusion While the cardiovascular deaths related to mechanical complications of CIED were decreasing over the past decades, disparities in the AAMRs across sex, races and geographical region still present.
