Overview
Abdominal aortic aneurysm is the 13th leading cause of death in the US.
Epidemiology and Demographics
Age
- Abdominal aortic aneurysms (AAA) is a disease of the elderly, and is the 10th leading cause of death in older men in the United States.
- An individual's risk of AAA increases by 6% per decade of life
- Rupture of the AAA occurs in 1-3% of men aged 65 or more with an associated mortality rate of 70-95%[1].
- AAA tends to cluster in families, therefore affecting younger members of families in the absence of traditional acquired risk factors.
Gender
- The frequency rate varies strongly between males and females.
- The peak incidence is among males around 70 years of age, the prevalence among males over 60 years totals 2-6%.
- Other risk factors include hypertension and male sex.[2]
- The prevalence is 2-5 times higher in men and 2-3 times higher in women with other cardiovascular risk factors or atherosclerotic cardiovascular diseases, than in control groups without risk factors.
Race
- The disease tends to affect older Caucasian males.
Developed Countries
- In the US, the incidence of AAA is 2-4% in the adult population.
Developing Countries
- AAA is uncommon in individuals of African, African American, Asian and Hispanic heritage.
Other
- The frequency is much higher in smokers than in non-smokers (8:1)
