[A three years longitudinal follow-up study of pulmonary function changes in patients with chronic obstructive pulmonary disease].
To investigate the characteristics and the risk factors of pulmonary function in patients with chronic obstructive pulmonary disease (COPD) for a 3 year follow-up. ⋯ The changes of pulmonary function in patients with COPD are heterogeneous, although most patients are treated in a standard way. Nearly 80% patients still represent deterioration of pulmonary function. Decline of FEV1 is closely related to the initial pulmonary function and bronchodilator reversibility.
