Annual FEV1 Loss in Patients with Noncystic Fibrosis Bronchiectasis and Affecting Factors.
Bronchiectasis is a chronic respiratory disease characterized by sputum production, cough, and several bronchial infections. Lung function is an important parameter to evaluate and study in patients with bronchiectasis. This study aimed to evaluate the annual changes in forced expiratory volume in one second (FEV1) and related factors in patients with with noncystic fibrosis bronchiectasis. ⋯ An annual mean FEV1 loss of 39 mL was found in adult patients with noncystic fibrosis bronchiectasis. The annual mean FEV1 decline was found to be associated with the baseline FEV1 value. Physicians should exercise caution in this regard in patients with bronchiectasis with low FEV1 values.
