The Right Atrial Coupling Index is significantly associated with prior COPD-related hospitalizations and reduced exercise capacity, outperforming its individual echocardiographic components.
Does the Right Atrial Coupling Index (RACI) correlate with prior hospitalizations and functional decline in stable COPD patients?
RACI may serve as a useful novel echocardiographic index for characterizing right heart burden and functional decline in stable COPD patients.

RACI is significantly associated with a history of COPD-related hospitalizations and with reduced exercise capacity. As a cross-sectional discriminative marker, RACI outperformed its individual components and may serve as a useful echocardiographic index for characterizing right heart burden in stable COPD patients. Prospective longitudinal studies are warranted to establish its predictive validity for future exacerbation events.
