The burden of VHD-related HF is increasing in G20 countries, driven by rheumatic VHD-related HF, highlighting a growing public health challenge.
BACKGROUND: The aim of this study was to characterize the burden of valvular heart disease (VHD)-related heart failure (HF) in Group of 20 (G20) countries. METHODS AND RESULTS: Using data from the 2019 Global Burden of Disease Study, we estimated VHD-related HF burdens (cases, age-standardized prevalence rates, and years lived with disabilities rates) in G20 countries from 1990 to 2019 by age, sex, and sociodemographic index. The burden of VHD-related HF increased in G20 countries from 1990 to 2019, exhibiting heterogeneity across VHD subtypes. In 2019, Italy, the United States, and the Russian Federation had the highest age-standardized prevalence rates of nonrheumatic VHD-related HF, whereas India, Brazil, and Mexico had the lowest. Rheumatic VHD-related HF was most prevalent in China, India, and Italy, whereas the Republic of Korea, Brazil, and Turkey had the lowest. Nonrheumatic VHD-related HF prevalence peaked among G20 countries in individuals ≥85 years of age, whereas rheumatic VHD-related HF peaked in those 75 to 84 years of age in several countries, including China, India, the Russian Federation, Mexico, Argentina, and Turkey. Age-standardized prevalence rates of nonrheumatic VHD-related HF showed a decreasing trend, more pronounced in women, whereas rheumatic VHD-related HF increased in both sexes, with a lower increase in men. Nonrheumatic VHD-related HF burden correlated with age and sociodemographic index, whereas rheumatic VHD-related HF burden was highest in middle sociodemographic index countries for those <75 years of age. Years lived with disabilities rates for VHD-related HF represented about 9.0% of the overall burden across populations. CONCLUSIONS: The increasing burden of VHD-related HF in G20 countries highlights the need for timely interventions to mitigate this growing public health challenge.
