Chronic Obstructive Pulmonary Disease and Heart Failure: A Breathless Conspiracy.

Heart failure (HF) and chronic obstructive pulmonary disease (COPD) are both common causes of breathlessness and often conspire to confound accurate diagnosis and optimal therapy. Risk factors (such as aging, smoking, and obesity) and clinical presentation (eg, cough and breathlessness on exertion) can be very similar, but the treatment and prognostic implications are very different. This review discusses the diagnostic challenges in individuals with exertional dyspnea. Also highlighted are the prevalence, clinical relevance, and therapeutic implications of a concurrent diagnosis of COPD and HF.
