Global, Regional, and National Burden of Nonrheumatic Valvular Heart Disease and Its Attributable Risk Factors in 204 Countries and Territories, 1990 to 2019: Results From the Global Burden of Disease Study 2019.

BACKGROUND

Nonrheumatic valvular heart disease (NRVD) is increasingly becoming a significant public health concern, particularly among older people. In the context of population aging, a detailed report on the epidemiological trends of NRVD is crucial for policymakers to effectively allocate health care resources. This study aimed to explore these trends using data from the GBD (Global Burden of Disease) 2019 study.

METHODS AND RESULTS

We assessed the changing trends of the incidence, mortality, and disability-adjusted life years rates for NRVD by calculating the estimated annual percentage change for each. Additionally, we examined the impact of a region's level of social development on NRVD epidemiological trends and identified key risk factors contributing to NRVD-related deaths. Between 1990 and 2019, the global incidence of NRVD showed a gradual increase, with an estimated annual percentage change of 0.39 (95% CI, 0.30-0.48). The data revealed that women and older people are more likely to develop NRVD. High-sociodemographic index countries exhibited higher age-standardized incidence and mortality rates compared with low- and middle-sociodemographic index countries. The most significant risk factor for NRVD-related mortality was identified as high systolic blood pressure.

CONCLUSIONS

Over the past 3 decades, the burden of NRVD has intensified, indicating a need for more health care resources to address this issue, which is closely associated with an aging population. Currently, high-sociodemographic index countries report the highest incidences and deaths due to NRVD. However, low- and middle-sociodemographic index countries should also implement measures to manage the rapidly increasing burden of NRVD.
