Insights
Calcific aortic valve disease (CAVD) cases are rising globally, with increasing prevalence and incidence but declining mortality rates. Targeted prevention strategies are crucial due to age, sex, and regional disparities in CAVD burden.
Area of Science:
- Cardiology
- Public Health
- Epidemiology
Background:
- Calcific aortic valve disease (CAVD) is a leading nonrheumatic valvular heart condition.
- It imposes a significant global health burden, necessitating an understanding of its trends.
Purpose of the Study:
- To analyze global CAVD trends from 1992 to 2021.
- To provide insights for developing effective CAVD prevention strategies.
- To project future CAVD trends through 2036.
Main Methods:
- Utilized Global Burden of Disease Study 2021 (GBD 2021) data.
- Analyzed age-standardized prevalence, incidence, mortality, and DALYs.
- Examined age- and sex-specific patterns, contributing factors, and regional disparities.
Main Results:
- Global CAVD cases increased from 4.97 to 13.32 million (1992-2021).
- Age-standardized prevalence and incidence rates rose, while mortality and DALY rates declined.
- CAVD burden increased with age, showed higher rates in males, but higher mortality in females over 85.
- Burden correlated positively with Sociodemographic Index (SDI), with widening gaps between High and Low SDI regions.
Conclusions:
- Population growth and aging are key drivers of increasing CAVD burden.
- Epidemiological transitions reduced mortality/DALYs in High SDI regions.
- Projections indicate declining rates in High/High-middle SDI regions by 2036, but rising prevalence/incidence elsewhere.
- Targeted strategies are needed to address demographic and regional disparities in CAVD.
Abstract:
Calcific aortic valve disease (CAVD) is among the most prevalent forms of nonrheumatic valvular heart disease, imposing a substantial global health burden. This study examined CAVD trends to provide insights for the development of effective prevention strategies. Using Global Burden of Disease Study 2021 (GBD 2021) data, we analyzed the age-standardized prevalence, incidence, mortality, and disability-adjusted life years (DALYs) of CAVD, along with trends, age- and sex-specific patterns, contributing factors, and projections through 2036. From 1992 to 2021, the number of global CAVD cases rose from 4.97 to 13.32 million and the age-standardized prevalence rate (ASPR) increased from 130.82 to 158.35 per 100,000 people. While both the ASPR and age-standardized incidence rate (ASIR) steadily increased, the age-standardized mortality rate (ASMR) and age-standardized DALYs rate (ASDR) declined. The burden of CAVD progressively worsened with age. Males generally had higher prevalence and incidence rates compared with females. However, in individuals > 85 years, females exhibited significantly higher mortality and DALY burdens. The CAVD burden was positively correlated with the sociodemographic index (SDI); the correlation was stronger in High SDI regions compared with Low SDI regions, and this gap widened over the last three decades. Population growth and aging were the primary contributors to the increasing burden, while epidemiological transitions helped reduce the ASMR and ASDR in regions with a high SDI. By 2036, the ASPR, ASIR, ASMR, and ASDR of CAVD are projected to decline in the High and High-middle SDI regions. In contrast, the ASPR and ASIR are expected to continue to increase, whereas the ASMR and ASDR are anticipated to remain relatively stable in other SDI regions. Although significant progress has been made globally in the prevention and treatment of CAVD, the complex demographic and regional disparities underscore the need for targeted prevention and treatment strategies to further alleviate the burden and enhance patient outcomes.
