Cardiac disease in chronic obstructive pulmonary disease

Area of Science:

• Cardiology
• Pulmonology
• Internal Medicine

Background:

• Chronic obstructive pulmonary disease (COPD) is associated with numerous cardiac manifestations.
• Right ventricular dysfunction and pulmonary vascular disease are significant complications of COPD, inversely correlating with survival.
• The pathogenesis of pulmonary vascular disease in COPD is multifactorial, involving gas exchange, vascular biology, structural changes, and mechanical factors.

Purpose of the Study:

• To review the cardiac manifestations of COPD.
• To discuss the assessment and management of pulmonary vascular disease and pulmonary hypertension in COPD.
• To explore the frequent coexistence of COPD and coronary artery disease and the management of arrhythmias in COPD patients.

Main Methods:

• Literature review of cardiac manifestations in COPD.
• Discussion of diagnostic modalities for pulmonary vascular disease, highlighting right heart catheterization as the gold standard.
• Analysis of treatment strategies for pulmonary hypertension and cardiac comorbidities in COPD.

Main Results:

• Right ventricular dysfunction and pulmonary vascular disease are prevalent and impact survival in COPD.
• Right heart catheterization is the gold standard for assessing pulmonary vascular disease.
• Coexistence of COPD and coronary artery disease is common, linked by shared risk factors and systemic inflammation.
• Arrhythmias are frequent in COPD but generally manageable with medical treatment.
• Cardioselective beta-blockers are generally safe for cardiac disease management in COPD patients.

Conclusions:

• Cardiac complications, including right ventricular dysfunction and pulmonary hypertension, are integral to the clinical course of COPD.
• While specific therapies for pulmonary hypertension in COPD are limited, pulmonary vasodilators are under renewed investigation.
• Concurrent COPD and coronary artery disease require tailored management considering respiratory limitations.
• Arrhythmias in COPD are typically manageable, and beta-blocker use is generally safe with cardioselective agents.
