The global age-standardized mortality rate for aortic aneurysm declined from 2.54 to 1.86 per 100,000 population between 1990 and 2021, though pronounced regional differences persist, and improved behavioral and metabolic risk management could substantially reduce rates to 0.84 by 2050.
Key Findings
Results
In 2021, there were an estimated 153.93 thousand deaths globally due to aortic aneurysm.
Data were drawn from the Global Burden of Disease Study 2021, encompassing 204 countries and territories
Aortic aneurysm was defined as a full-thickness dilation of the aorta, including both abdominal and thoracic types
Results
The global age-standardized mortality rate (ASMR) for aortic aneurysm declined from 1990 to 2021.
ASMR decreased from 2.54 (95% UI, 2.35–2.69) in 1990 to 1.86 (95% UI, 1.67–2.00) per 100,000 population in 2021
Age-standardized years of life lost (YLL) rates declined from 48.79 (95% UI, 46.01–51.80) to 36.54 (95% UI, 33.52–39.46) per 100,000 population over the same period
The study period covered 1990 to 2021 across 204 countries and territories
Results
Regional disparities in aortic aneurysm burden persist, with high-SDI regions still carrying a significant mortality burden while lower-SDI regions show an increasing trend.
High SDI areas had an ASMR of 2.87 (95% UI, 2.51–3.06) per 100,000 population
High-middle SDI areas had an ASMR of 1.79 (95% UI, 1.66–1.92) per 100,000 population
Regions with higher SDI exhibited a sharp decline in burden, whereas regions with lower SDI demonstrated an increasing trend
The burden was stratified by geographical region, age, year, sex, and Socio-demographic Index (SDI)
Results
Males consistently exhibited a higher aortic aneurysm burden than females, and burden increased with age.
Sex-based stratification was applied across the full study period (1990–2021)
Tobacco use was identified as a more significant risk factor in males
High systolic blood pressure was identified as a more prominent risk factor in females
Burden increased with advancing age across both sexes
Results
Tobacco use and high systolic blood pressure were the predominant risk factors for aortic aneurysm-related mortality.
Attributable risk factor analysis was conducted as part of the GBD 2021 framework
Tobacco use was the dominant risk factor in males
High systolic blood pressure was the dominant risk factor in females
These two risk factors were identified as predominant across the global population
Results
Projections suggest the global ASMR for aortic aneurysm will remain relatively stable under a reference scenario but could be substantially reduced with improved risk management by 2050.
Under the reference scenario, projected ASMR was 1.87 (95% UI, 1.67–2.02) in 2022 and 1.44 (95% UI, 1.23–1.70) in 2050
Improved behavioral and metabolic risk management—modeling elimination of smoking, dietary risks, and high BMI—could reduce ASMR to 0.84 (95% UI, 0.71–0.99) by 2050
This represents a reduction of approximately 42% compared to the reference scenario projection for 2050
Scenario modelling was used to evaluate the potential impact of eliminating smoking, dietary risks, and high body mass index among adults
What This Means
This research suggests that deaths from aortic aneurysms—dangerous bulges in the body's main artery that can burst without warning—have declined globally over the past three decades, but the problem remains significant and varies widely by region. Between 1990 and 2021, the age-adjusted death rate dropped from about 2.54 to 1.86 per 100,000 people worldwide. However, wealthier regions saw the steepest improvements, while lower-income regions actually experienced an increasing burden, highlighting that not all populations have benefited equally from advances in detection and treatment.
The study also identified key risk factors driving aortic aneurysm deaths: smoking is the leading risk factor for men, while high blood pressure is the leading risk factor for women. Men overall face a higher burden than women, and risk increases substantially with age. These findings point to clear targets for prevention efforts tailored by sex and region.
Looking ahead to 2050, this research suggests that without major changes, death rates will only modestly decline. However, if societies successfully reduce smoking, improve diet, and control obesity at a population level, the death rate could be cut nearly in half compared to doing nothing extra. This underscores that aortic aneurysm is a largely preventable condition, and that investments in public health measures targeting lifestyle and metabolic risk factors could have a major impact on future deaths from this silent but deadly disease.
