Global, regional, and national burden of heart failure and its underlying causes, 1990–2021: results from the global burden of disease study 2021

Heart failure (HF) remains a significant public health challenge globally. This study aims to systematically analyze the global HF disease burden from 1990 to 2021 across temporal, spatial, and demographic dimensions to provide evidence for targeted prevention and control strategies.

Using data from the Global Burden of Disease (GBD) 2021 study, we analyzed the global HF burden through prevalent cases, years lived with disability (YLDs), and age-standardized rates per 100,000 population. Temporal trends were evaluated using estimated annual percentage change (EAPC) and joinpoint regression analysis. The relationship between the Socio-demographic Index (SDI) and disease burden was explored through Pearson correlation analysis, while attribution analysis identified the main causes of HF. When appropriate, analyses were stratified by 5 SDI regions, 21 GBD regions, 204 countries and territories, 20 age groups, and both sexes.
