title: Frequency of abdominal aortic aneurysm in patients undergoing coronary artery bypass grafting.
abstract: The aims of this study were to clarify the prevalence and the risk factors for unsuspected abdominal aortic aneurysm (AAA) in patients who underwent coronary artery bypass grafting for severe coronary artery disease and to identify the most at risk patients for AAA. Among 217 patients (189 men, mean age 64 +/- 11 years), asymptomatic AAAs, as prospectively identified by echocardiography, were found in 15 patients (6.9%). All patients with AAAs were men and smokers or past smokers. Factors significantly associated by univariate analysis with asymptomatic AAA presence were smoking (p = 0.003), symptomatic peripheral artery disease (p = 0.006), significant carotid artery stenosis (p = 0.007), and larger femoral and popliteal diameters (p = 0.008 and p = 0.0012, respectively). The other classic demographic, clinical, and biologic features were equally distributed among patients. In conclusion, in patients who underwent coronary artery bypass grafting who were men and aged <75 years with smoking histories, the prevalence of AAA was as high as 24% when they had concomitant peripheral arterial disease and/or carotid artery stenosis (vs 4.4% in the absence of either condition, p = 0.007), justifying consideration of AAA screening in this subgroup of in-hospital patients.
