Résumé :

The results underscore a multifaceted interaction among cardiopulmonary hemodynamics, right heart pressures, ventilatory response, and autonomic regulation. In particular, altered RV-PA coupling correlated with heightened sympathetic drive, indicating that cardiopulmonary efficiency and hemodynamics may influence central autonomic outputs. This suggests that mechanical stress or overload in the right heart could modulate sympathovagal balance, thereby contributing to altered autonomic responses during exercise in patients with cardiopulmonary disorders.
