ABDOMINAL AORTIC ANEURYSM IN THE BRAZILIAN PUBLIC HEALTH SYSTEM: HOSPITAL MORTALITY AND AGE DISTRIBUTION

Abstract

Abdominal aortic aneurysm and abdominal aortic dissection are severe vascular conditions associated with high morbidity and mortality, especially in older age groups. This study aimed to analyze the distribution of deaths from abdominal aortic aneurysm and dissection in Brazil according to age group from 2015 to 2024. This was an epidemiological, ecological, retrospective, descriptive, and quantitative study based on secondary public-domain data. Deaths were assessed across the following age groups: 20 to 29, 30 to 39, 40 to 49, 50 to 59, 60 to 69, 70 to 79, and over 80 years. During the study period, 77,318 deaths were recorded, with a progressive increase in the absolute number of deaths as age advanced. The lowest frequencies were observed among individuals aged 20 to 29 years, with 547 deaths, and 30 to 39 years, with 1,658 deaths. In contrast, the highest values were concentrated in the 70 to 79 age group, with 23,290 deaths, followed by those older than 80 years, with 19,946. Individuals aged 60 years or older accounted for 79.6% of all deaths observed. It was concluded that mortality from abdominal aortic aneurysm and dissection in Brazil was strongly concentrated among older adults, highlighting age as an important epidemiological marker and reinforcing the need for early diagnosis and timely follow-up.
