Study of the relation between speckle tracking echocardiography and BODE index in patients with chronic obstructive pulmonary disease

Abstract

Background Chronic obstructive pulmonary disease (COPD) is a widespread lung disease with a high mortality and morbidity especially with co-morbid cardiac impairment. Severity of COPD can be assessed using BODE Index (body mass index, obstruction of airflow, dyspnea degree and exercise capacity). Aim To study the relationship between BODE index and right ventricle (RV) and left ventricle (LV) functions using Two-dimensional speckle-tracking echocardiography (2D-STE) in COPD patients. Subjects and methods Fifty stable COPD patients and matched fifty control subjects underwent transthoracic echocardiography, where conventional and speckle tracking parameters were taken. BODE indices were calculated and divided to quartiles (Q) (Q1; BODE index = 0–2, Q2; BODE index = 3–4 Q3; BODE index = 5–6, Q4; BODE index = 7–10). Results COPD patients had lower RV fractional area change (FAC%, P Conclusion COPD patients had RV, LV systolic dysfunction and LV diastolic dysfunction. The more COPD severity increased (assessed by BODE index) the more impairment of RV systolic function and LV diastolic function would be.
