Global, regional, and national burden of atrial fibrillation/flutter related to metabolic risks over three decades: estimates from the global burden of disease study 2019

Aims Atrial fibrillation/atrial flutter (AF/AFL) remains a significant public health concern on a global scale, with metabolic risks playing an increasingly prominent role. This study aimed to investigate comprehensive epidemiological data and trends concerning the metabolic risks related-AF/AFL burden based on the data from the Global Burden of Disease study in 2019.Methods and Results The analysis of disease burden focused on numbers, age-standardized rates of deaths, disability-adjusted life years (DALYs), and estimated annual percentage change, while considering factors of age, sex, sociodemographic index (SDI), and locations. In 2019, there was a culmination of 137 179 deaths and 4 099 146 DALYs caused by metabolic risks related-AF/AFL worldwide, with an increase of 162.95% and 120.30%, respectively from 1990. High and high-middle SDI regions predominantly carried the burden of AF/AFL associated with metabolic risks, while a shift towards lower SDI regions had been occurring. Montenegro had the highest recorded death rate (7.6 per 100 000) and DALYs rate (146.3 per 100 000). An asymmetrically inverted V-shaped correlation was found between SDI and deaths/DALYs rates. Moreover, females and the elderly exhibited higher AF/AFL burdens, and young adults (over 40 years old) also experienced an annual increase.Conclusion The global AF/AFL burden related to metabolic risks has significantly increased over the past three decades, with considerable spatiotemporal, gender-based, and age-related heterogeneity. These findings shed valuable light on the trends in the burden of metabolic risks related-AF/AFL and offered insights into corresponding strategies.
