# The burden of atrial fibrillation/atrial flutter in Europe from 1990 to 2021, with a forecast of incidence through 2044

## TL;DR

This study examines how the health impact of atrial fibrillation and flutter has changed in Europe from 1990 to 2021 and predicts future trends.

## Contribution

The study provides updated and region-specific estimates of AF/AFL burden and forecasts future incidence in Europe.

## Key findings

- AF/AFL caused over 1 million new cases and nearly 100,000 deaths in Europe in 2021.
- Western Europe and the EU-28 had higher age-standardized rates of AF/AFL burden compared to other regions.
- The number of AF/AFL cases is projected to rise across all European subregions through 2044.

## Abstract

The objective of this analysis was to assess the impact of atrial fibrillation (AF)/atrial flutter (AFL) across various European regions and countries from 1990 to 2021.

Using the global burden disease 2021 analytical tools, this study evaluated the incidence, prevalence, disability-adjusted life years (DALYs) and death associated with AF/AFL across the European Region, as defined by the World Health Organization, which includes 53 member countries (EU-53), as well as the European Union, as defined in 2019, consisting of 28 member countries (EU-28) from 1990 to 2021.

The EU-53, in 2021, there were 957,812 incident cases [95% uncertainty interval (UI): 773,898 to 1,178,186], 103,043 deaths (95% UI: 86,887 to 111,924), and 2,196,895 DALYs (95% UI: 1,847,967 to 2 596 530) attributed to AF/AFL. The age-standardized rates (ASRs) of incidence, prevalence, death, and DALYs were respectively 1.16, 1.14, 1.06, and 1.10 times higher in the EU-28 compared to the EU-53. The absolute number of AF/AFL incidents is projected to increase from 2021 to 2044 across Western Europe (from 600,735 to 723,218), Eastern Europe (from 176,794 to 190,803), and Central Europe (from 122,625 to 135,877).

Despite substantial efforts to manage AF/AFL in Europe, it remains a significant public health challenge. The burden of AF/AFL varies considerably across European countries and subregions, as well as between different EU classifications (EU-28 vs. EU-53). In Western Europe and the EU-28, which include many developed nations, higher ASRs of deaths, DALYs, prevalence, and incidence have been reported.
