Current research status on treatable traits of chronic obstructive pulmonary disease
Chronic obstructive pulmonary disease(COPD)is a heterogeneous disease,while COPD is a highly preventable and treatable disease.Treatable traits of COPD include pulmonary features dominated by cough,phlegm and dyspnea,extrapulmonary features dominated by cardiovascular comorbidities,anxiety and depression,sleep disorders and skeletal muscle dysfunction,behavioral features dominated by smoking and limited physical activity,and treatable features guided by biomarkers including FeNO and eosinophil counts.This article systematically reviews the research status of treatable traits of COPD.
