Extract
The underlying pathophysiological determinants of asthma and chronic obstructive pulmonary disease (COPD) are related in complex ways. Importantly however, post-bronchodilator FEV1-reversibility may occur in approximately 50% of COPD patients [1] whilst epidemiological [2] and magnetic-resonance-imaging (MRI) studies [3] suggest that in asthmatics, FEV1-reversibility may diminish over time. As compared to patients with asthma or COPD alone, patients with co-existing asthma and COPD report worse clinical outcomes [4] and increased healthcare costs [5] and burden [4, 5].
