Abstract
- BACKGROUND Aortic aneurysm (AA) is an enlargement of the aorta to greater than 1.5 times normal size. Although the US guideline recommends ultrasound screening for abdominal AA (AAA) in men older than 65 years regardless of symptoms, limited data describe the prevalence of AAA in Korea. In this study, we screened patients for AAA during transthoracic echocardiographic examination (TTE). METHODS We screened for AAA in all consecutive subjects older than 60 years who underwent TTE. We defined AAA as an abdominal aorta with the diameter greater than 30 mm. RESULTS We analyzed 5,679 persons (2,272 females, 74 ± 8 years old). The mean size of the abdominal aorta was 19.0 ± 6.1 mm. The prevalence of AAA was 2.9% (165/5,679) and was significantly higher in males (4.7% vs. 1.1%, p < 0.001). AAA was significantly associated with male sex (odds ratio [OR] = 3.098, 95% confidence interval [CI] = 1.971-4.870, p < 0.001), older age (OR = 1.074, 95% CI = 1.050-1.097, p < 0.001), non-diabetes (OR = 1.886, 95% CI = 1.264-2.813, p < 0.001), dyslipidemia (OR = 1.475, 95% CI = 1.019-2.135, p = 0.040), ever-smoker (OR = 2.090, 95% CI = 1.448-3.015, p < 0.001), chronic kidney disease (CKD, OR = 1.757, 95% CI = 1.182-2.612, p = 0.005), and coronary artery disease (CAD, OR = 2.452, 95% CI = 1.742-3.451, p < 0.001). A prediction score with a multivariate model (range: 3.34-10.51) detected AAA with a sensitivity of 79.4% and a specificity of 66.8% with a reference value > 6.8 (area under the curve = 0.799). CONCLUSIONS In Korea, the prevalence of AAA was 2.9% in subjects older than 60 years during TTE, and AAA was significantly associated with older age, male sex, non-diabetes, dyslipidemia, ever-smoker, CKD, and CAD. Prediction score (> 6.8%) detected AAA with a sensitivity of 79.4% and a specificity of 66.8%.
