Summary
Patients with abdominal aortic aneurysms (AAA) have higher rates of co-morbidity, including myocardial infarction and claudication. This increased comorbidity may impact surgical outcomes and long-term survival in AAA patients.
Area of Science:
- Vascular Surgery
- Epidemiology
- Diagnostic Imaging
Background:
- Abdominal aortic aneurysm (AAA) management involves risk assessment comparing surgical risks with rupture risks.
- Co-morbidity levels in patients with AAA are not fully understood and may influence treatment decisions.
Purpose of the Study:
- To assess co-morbidity levels in individuals screened for abdominal aortic aneurysms (AAA).
- To determine if co-morbidity differs between individuals with and without AAA detected via ultrasound.
Main Methods:
- A two-year screening of 5392 individuals aged 65-80 using B-mode linear ultrasound.
- Questionnaires collected data on angina, stroke, claudication, myocardial infarction, respiratory problems, and diabetes.
- Logistic regression analysis adjusted for co-morbidities, smoking, sex, and age.
Main Results:
- 218 individuals had AAA (≥3 cm).
- Myocardial infarction (OR 1.66) and claudication (OR 1.68) were significantly associated with AAA in both sexes.
- Stroke showed a significant association only in women (OR 3.71).
- Angina association was of borderline significance (OR 1.52).
Conclusions:
- Individuals with ultrasound-detected AAA exhibit significantly higher co-morbidity.
- These co-morbidities may influence surgical outcomes and long-term survival in AAA patients.
