Effects of long-term bronchodilators in bronchiectasis patients with airflow limitation based on bronchodilator response at baseline

Abstract

Positive BDR at baseline was independently associated with responsiveness to long-term bronchodilator therapy in bronchiectasis patients with airflow limitation. However, FEV₁ improvement was also evident in bronchiectasis patients without positive BDR at baseline, suggesting that these patients can benefit from long-term bronchodilator therapy.
