Chronic Obstructive Pulmonary Disease and Heart Failure: Closer than Close.

Chronic obstructive pulmonary disease (COPD) and heart failure (HF) both are global epidemics with substantial burden on morbidity and mortality. They present major challenges to healthcare providers and often coexsist. Multiple interactions exist between these conditions. COPD is often responsible for delayed diagnosis of HF and vice versa, since both conditions have similar symptoms such as dyspnea and poor exercise tolerance based on the skeletal myopathic response rather than the primary organ failure. Patients with COPD also have an increased risk of developing HF and higher hospitalization and death rates compared with HF patients without COPD. Echocardiography and pulmonary function tests along with natriuretic peptides should be performed and carefully interpreted. Diagnostic assessment of both conditions present in the same patient is often difficult, but therapeutic approach is also often non-adherent to current guidelines. For example, patients with coexisting COPD and HF receive beta-blockers at disappointingly low rates below 20%. Closer collaboration between cardiologists and pulmonologists is required for better identification and management of concurrent COPD and HF.
