Abstract
Results: The 3- and 5-year survival rates were 98% and 83%, respectively. The median survival time was 78 months. The median survival time was 55 months in 322 patients with one or more acute exacerbations. The 3- and 5-year survival rates were significantly lower in the 322 patients with one or more acute exacerbations than in those without any. The mortality rate was significantly higher in patients with CRP ＞3 mg/L than in those with CRP ≤3 mg/L (p＜0.005); it was significantly higher in patients with pulmonary hypertension than in those without it (p＜0.01). Conclusion: Because the 5-year survival rate is 83% in Korean patients with COPD, the management of stable patients with COPD should focus on the prevention of acute exacerbations.
