[Risk factors for mortality in chronic obstructive pulmonary disease].
Although the factors predictive of survival in patients with chronic obstructive pulmonary disease (COPD) have been widely studied, full consensus has yet to be reached. The objective of this study was to further clarify how lung function parameters, exercise tolerance, and quality of life influence survival in patients with COPD. ⋯ Our findings show that peak exercise tolerance is the best predictor of survival in patients with COPD.
