Left ventricular concentric remodeling in COPD patients: A cross-sectional observational study

Area of Science:

• Cardiology
• Pulmonology
• Medical Imaging

Background:

• Chronic Obstructive Pulmonary Disease (COPD) is a progressive lung disease.
• COPD significantly impacts systemic health, including cardiovascular function.
• Left ventricular (LV) remodeling is increasingly recognized in COPD patients.

Purpose of the Study:

• To investigate the association between left ventricular (LV) structure and COPD disease severity.
• To determine if specific echocardiographic parameters correlate with COPD severity indices.

Main Methods:

• Twenty-eight COPD patients were stratified into lower (BODE <5) and higher (BODE ≥5) severity groups.
• Left ventricular (LV) structure was assessed using 2D-echocardiography.
• The BODE index, incorporating BMI, FEV1, mMRC, and 6MWD, quantified disease severity.

Main Results:

• Higher severity COPD patients had lower oxygen saturation, FEV1, and 6MWD.
• Patients with higher COPD severity exhibited increased relative posterior wall thickness (RWT).
• Significant associations were found between LV dimensions (LVESD, LVEDD), interventricular septal thickness, and COPD severity markers (BODE index, FEV1, BMI, 6MWD).

Conclusions:

• Severe COPD (BODE score ≥5) is associated with increased LV RWT, suggesting concentric remodeling.
• Greater COPD severity may correlate with a reduction in LV chamber size.
• These findings highlight cardiac structural changes in advanced COPD.
