Global burden of rheumatic heart disease and its association with socioeconomic development status, 1990-2019.

Rheumatic heart disease (RHD) remains an important health issue, yet global attention to RHD is diminishing. This study aimed to investigate the global burden of RHD and its relationship with socioeconomic development status. Data were obtained from the Global Burden of Disease (GBD) 2019 database. Incidence, prevalence, disability-adjusted life years (DALYs), and mortality numbers and rates for RHD were extracted and stratified by sex, level of socio-demographic index (SDI), country, and territory. In addition, the burden of RHD was compared across age groups. From 1990 to 2019, the age-standardized incidence and prevalence rates of RHD increased by 14.4% (11.2-17.0%) and 13.8% (11.0-16.0%), respectively. Incidence and prevalence rates showed an increasing trend in low SDI and low-middle SDI locations, while high-middle SDI and high SDI locations showed a decreasing trend. The age-standardized DALYs and mortality rates of RHD decreased by 53.1% (46.4-60.0) and 56.9% (49.8-64.7%), and this downward trend was more prominent in high-middle SDI and middle SDI locations. In addition, the age of incidence and prevalence rates were concentrated between 5-24 years and 15-49 years, predominantly in poor regions, and RHD appeared to be more common in women than in men. The burden of RHD is negatively correlated with socioeconomic development status. In particular, the burden of RHD among children, adolescents, and women of childbearing age in poorer regions requires more attention. Policymakers should use the 2019 GBD data to guide cost-effective interventions and resource allocation for RHD.

Spatiotemporal trends in global burden of rheumatic heart disease and associated risk factors from 1990 to 2019.

The aim of this study was to estimate the burden of rheumatic heart disease (RHD) and its trends in different countries, regions, genders and age groups globally. Data were obtained from the Global Burden of Disease 2019 study. Age-standardized rates (ASRs) and the estimated annual percentage changes (EAPCs) in the ASRs were used to describe the burden of disease and its trends. Pearson's correlation was used to evaluate the correlation between sociodemographic index (SDI) values and the observed trends. In 2019, the ASRs of the incidence, prevalence, mortality and disability-adjusted life years (DALYs) of RHD were 37.39/105 (95%UI, 28.59/105 to 46.74/105), 513.68/105 (95%UI, 405.01/105 to 636.25/105), 3.85/105 (95%UI, 4.29/105 to 3.29/105) and 132.88/105 (95%UI, 115.02/105 to 150.34/105), respectively. From 1990 to 2019, the incidence and prevalence of RHD showed upward trends and the mortality and DALYs showed downward trends. Countries or regions in Africa, South America and South Asia had a greater burden of RHD. The burden of RHD was greater in women, where as men showed more obvious increasing trends in the incidence and prevalence. The incidence of RHD was highest in adolescents, and the prevalence was highest in young and middle-aged. The mortality and DALYs rate associated with RHD increased with age. The EAPCs in the ASRs were negatively correlated with the SDI value. Although the ASRs of mortality and DALYs attributable to RHD are decreasing globally, RHD remains an important public health problem that needs to be addressed urgently, especially in certain low- and middle-income countries and regions.

Analysis and comparison of the trends in burden of rheumatic heart disease in China and worldwide from 1990 to 2019.

This study aimed to describe the temporal trends in age and gender burdens of rheumatic heart disease (RHD) in China from 1990 to 2019, including incidence, prevalence, mortality, and disability-adjusted life years (DALYs), and to compare them with the global burden of the disease. Using open data from the Global Burden of Disease (GBD) database from 1990 to 2019, this study analyzed the characteristics of RHD burden in China and worldwide, including changes in incidence, prevalence, mortality, and DALYs. Joinpoint was used to calculate the average annual percentage change (AAPC) and the corresponding 95% confidence interval (95% CI) to reflect the trends in the burden of RHD. A comprehensive comparative analysis of the differences in RHD burden between China and the rest of the world was conducted from multiple dimensions, including age, gender, and time periods. From 1990 to 2019, the age-standardized incidence rate (ASIR) of RHD in China decreased from 29.62/100,000 to 23.95/100,000, while the global ASIR increased from 32.69/100,000 to 37.40/100,000. The age-standardized prevalence rate (ASPR) in China decreased from 446.15/100,000 to 390.24/100,000, while the global ASPR increased from 451.56/100,000 to 513.68/100,000. The age-standardized rates of mortality (ASMR) in China decreased from 18.11/100,000 to 4.04/100,000, while the global ASMR decreased from 8.94/100,000 to 3.85/100,000. The age-standardized DALY rate (ASDR) in China decreased from 431.45/100,000 to 93.73/100,000, while the global ASDR decreased from 283.30/100,000 to 132.88/100,000. The AAPC of ASIR, ASPR, ASMR, and ASDR in China was - 0.73%, -0.47%, -5.10%, and - 5.21%, respectively, while the AAPC of the global burden of RHD was 0.48%, 0.45%, -2.87%, and - 2.58%, respectively. The effects of age and gender on the burden of RHD were different. ASIR generally decreased with increasing age, while ASPR increased first and then decreased. ASMR and ASDR increased with increasing age. Women had higher incidence and mortality rates of RHD than men. From 1990 to 2019, the incidence, prevalence, mortality, and DALYs of RHD in China decreased, indicating a relative reduction in the burden of RHD in China. The burden of RHD is age-related, with a higher prevalence observed in the younger population, a peak incidence among young adults, and a higher mortality rate among the elderly population. Women are more susceptible to RHD and have a higher risk of mortality than men. Given China's large population and aging population, RHD remains a significant public health challenge in China.
