"One in four hospital beds in Canada is occupied by a COPD patient, and many of them return to a hospital because they're not being optimally treated," Dr. Parraga said. "Our study shows that when COPD symptoms and exercise limitations are discordant with FEV1 measurements, we should consider using lung imaging to provide a deeper understanding of the patient's disease and to help improve their quality of life."
The researchers plan future studies to see if imaging can help explain symptoms and disease control in people with asthma, another common lung disease, and cystic fibrosis, a hereditary disorder that damages the lungs and digestive system.
"COPD: Do Imaging Measurements of Emphysema and Airways Disease Explain Symptoms and Exercise Capacity?" Collaborating with Dr. Parraga were Miranda Kirby, Ph.D., Damien Pike, B.Sc., Don D. Sin, M.D., M.P.H., Harvey O. Coxson, Ph.D., and David G. McCormack, M.D., FRCPC
