Key result
RV dysfunction on echocardiography correlates with greater COPD severity and duration, with pulmonary hypertension in ~50%.
Why the study?
COPD has considerable effects on cardiac functions and most increased mortality and morbidity in COPD is due to cardiac involvement, necessitating assessment of ECG and echocardiographic findings.
Population
50 COPD patients staged by PFT with 8% mild, 44% moderate, 36% severe, 12% very severe
Comparison
Clinical, electrocardiographic, and echocardiographic findings in detecting right ventricular dysfunction
Design
Cross-sectional study

Cardiac involvement, particularly right ventricular dysfunction and pulmonary hypertension, is highly prevalent in COPD patients and correlates significantly with disease severity and duration, highlighting the need for early cardiac screening.
Musku et al. (2020) conducted a cross-sectional in Chronic Obstructive Pulmonary Disease (COPD) (n=50). COPD severity and duration was evaluated on Correlation of echocardiographic findings of right ventricular dysfunction (PAH, Cor pulmonale, RA dilatation, RVD, RVH, RVSD) with disease severity and duration (p=<0.05). Echocardiographic findings of right ventricular dysfunction, including pulmonary hypertension (50%) and cor pulmonale (44%), significantly correlated with COPD severity and duration (p < 0.05).
