A case study on Asthma-COPD Overlap (ACO) is independent from COPD

Abstract

Chronic Obstructive Pulmonary Disease (COPD) is characterized by irreversible airflow limitation in the lungs. COPD frequently coexist with Heart Failure (HF) but most patients go undiagnosed because of similarity of symptoms. Data on prevalence of COPD in HF are discrepant and scarce.
