Abstract
The study aim is to determine factors affecting the long-term survival of subjects with Aortic Aneurysm (AA). The sample included 294 Korean patients aged ≥ 30 years who were hospitalized from 1994 through 2004. Diagnosis was confirmed in 294 AA subjects (18.4% in affected Coronary Artery Disease (CAD); 75.8% with abdominal only AA (AAA) and 24.2% with Thoracic AA (TAA)) by computed tomography angiography in Samsung Medical Center, Seoul, Korea. AA repair direct operation or percutaneous endovascular AA repair (Revascularized group) was performed for 60.3% of the patients. Death data were obtained from all participants between 1994 and 2009. The mean age of AA subjects was 68.7 (±8.1) years. The proportion of males was 82%. Five- and 10-year survival rates were 89.8% and 82.6%, respectively. The 5-and 10-year survival rates were 92.3% and 84.9% in revascularized group and 86.4% and 79.5% in non-revascularized group, respectively. Adjusted hazard ratios were 1.14 (95% Confidence Interval (CI) 1.06-1.22) in ages and 2.94 (95% CI 1.23-7.38) in smoking for AA. Age and smoking contributed to death in Korean AA patients. And the 10-year survival rate for AA patients in Korea was over 80%. Revascularized group shows higher survival rate than non-revascularized group.
