Observational analysis explores heart function and COPD severity correlation among chronic obstructive pulmonary disease patients, indicating impaired hemodynamics.
Motivation: Chronic obstructive pulmonary disease (COPD) is associated with heart failure. Goal(s): To investigate hemodynamic changes in the left-sided heart chambers using 4D-flow MRI and evaluate their correlation with COPD severity. Approach: We analyzed fifty 4D-flow MRI cases from the SPIROMICS HF study. Results: A significant negative correlation was found between the energy loss to kinetic energy ratio and forced vital capacity in the left ventricle (r = -0.37, p =0.014). Maximum velocity in the aorta also negatively correlated with residual lung volume (r = -0.31, p = 0.035), indicating impaired left heart hemodynamics in COPD patients. Impact: Our findings emphasized using 4D-flow MRI as a noninvasive method for evaluating heart function in COPD patients. This opens new research into therapies targeting heart-lung interactions, improving outcomes that were previously unattainable.
