[Effect of a 2-year pulmonary rehabilitation on the 7-year prognosis in patients with advanced chronic obstructive pulmonary disease].
Pulmonary rehabilitation (PR) improve the quality of life in COPD patients, however, little has been known whether it may improve the survival. We assessed 7-year prognosis in 46 patients with advanced COPD, 27 of which completed successfully 2-year course of PR whereas 19 COPD patients made a control (C) group. At the end of 7-year observation 41.3% of total number of patients survived, among them 12 (42.8%) PR patients and 7 (38%) C patients. COPD progression was the main (80%) reason of mortality in both groups. The survivors had better results of baseline FVC, FEV1 and treadmill exercise test. They did not differ from non-survivors with age, baseline results of the weight, PaO2, PaCO2 and the number of PR patients. The Cox proportional hazard analysis showed that neither of baseline parameters influenced significantly the 7-year prognosis in this group of COPD patients. In conclusion, PR failed to improve 7-year prognosis in the studied group of patients with advanced COPD.
