Summary

This study found that 9.9% of patients over 65 with chronic obstructive airways disease (COPD) had abdominal aortic aneurysms (AAA). Severe emphysema and smoking were linked to higher AAA prevalence in COPD patients.

Area of Science:

  • Vascular Surgery
  • Pulmonology
  • Geriatrics

Background:

  • Chronic obstructive airways disease (COPD) is a common condition in older adults.
  • Abdominal aortic aneurysm (AAA) is a serious vascular condition with significant morbidity and mortality.
  • Screening for AAA in at-risk populations can aid early detection and intervention.

Purpose of the Study:

  • To determine the prevalence of abdominal aortic aneurysm (AAA) in elderly patients with chronic obstructive airways disease (COPD).
  • To investigate the association between COPD severity, smoking, and other risk factors with AAA prevalence.

Main Methods:

  • Prospective screening of 362 outpatients aged over 65 with COPD using ultrasonography.
  • Collection of data on pulmonary function tests, cardiovascular risk factors, and medication use.

  • Statistical analysis to compare AAA prevalence based on COPD severity and risk factors.

    • Main Results:

    • A prevalence of 9.9% for abdominal aortic aneurysm (AAA) (diameter >= 30 mm) was observed in the COPD patient cohort.
    • Patients with severe emphysema (FEV/VC < 55%) showed a significantly higher prevalence of AAA compared to those with mild/moderate COPD.
    • A significantly higher proportion of smokers were identified in the group with AAA compared to those without.

    Conclusions:

    • Elderly patients with COPD have a notable prevalence of abdominal aortic aneurysm (AAA).
    • Severe emphysema and a history of smoking are associated with an increased risk of AAA in COPD patients.
    • Ultrasonographic screening for AAA in COPD patients, particularly those with severe emphysema and smoking history, is warranted.
