Abstract
Objective
The aim of this study was to analyze the long-term survival of subjects with peripheral artery disease (PAD).
Methods
The data included 415 Korean PAD patients aged ≥20 years hospitalized from 1994 through 2004 at a single tertiary center in Korea. Death data were obtained from all participants between 1994 and 2009.
Results
The mean of age was 64.4±9.3 years in PAD. The proportion of peripheral vascular bypass operation (re-vascularized) was about 50%. The proportion of males was 90.6% in PAD. Five- and 10-year survival rates were 79.2% and 60.5% in PAD, respectively. The 5- and 10- year survival rates were 83.0% and 64.1% in re-vascularized group, and 75.5% and 56.3% in non-revascularized group (p<0.05). For PAD, the adjusted hazard ratios (HRs) were 1.75 (95% confidence interval (CI) 1.17-2.68) in over 65 years, 1.53 (95% CI 1.05-2.27) in diabetes, and 2.21 (95% CI 1.51-3.23) in chronic kidney disease (CKD). Interestingly, HRs in PAD were 0.55 (95% CI 0.34-0.84) in overweight and 0.45 (95% CI 0.25-0.76) in obesity.
