Trends in ventricular fibrillation/flutter mortality in US population, 1999 to 2019

Abstract

AbstractBackgroundThe Ventricular fibrillation and flutter (VF/VFL)‐related mortality trends in the United States (US) population have not yet been investigated. We aimed to assess the trends of VT/VFL‐related mortality from 1999 to 2019 among subjects aged more than 15 years old in the US.MethodsData derived from the Centers for Disease Control and Prevention's (CDC) WONDER were analyzed between 1999 and 2019 for VF/VFL‐related mortality in subjects aged more than 15 years of age. Adjusted mortality rates (AAMRs) per 100,000 people by year, sex, race and urban‐rural status with relative confidence intervals (CIs) were determined. Both the average annual percent change (AAPC) and the annual percent change (APC) with 95% Cis were calculated.ResultsBetween 1999 and 2019, 242,125 VT/VFL‐related deaths occurred in the US. The overall AAMR steadily declined [AAPC −4.4% (95% CI: −4.7 to −4.0, p < .0001)]. Women showed a more pronounced AAMRs decline [AAPC: −4.8% (95% CI: −5.3 to −4.3, p < .0001). AAMR steadily declined in white subjects and in those of other races [AAPC: −4.5 (95% CI: −4.7 to −4.2, p < .0001) and AAPC: −4.3 (95% CI: −5.1 to −3.5, p < .001), respectively]. Conversely, African Americans showed a steadily AMMR decline between 1999 and 2007 [APC: −8.3 (95% CI: −9.2 to −7.3, p < .0001)], followed by a period of stability from 2007 to 2019 (p = .73). A similar decline was observed for the AAMR among subjects living in urban and rural areas.ConclusionsVT/VFL‐related mortality steadily decreased between 1999 and 2019 in US. Despite the encouraging results, further efforts are needed to prevent VF/VFL‐related mortality in US subjects.
