Cox regression finds left-to-right chamber volume ratios signal heart failure and atrial fibrillation risk in healthy adults, suggesting predictive value for cardiac events.
Key Points
A high left-to-right ventricular volume ratio significantly increases the risk of heart failure, with a hazard ratio of 2.54.
In a cohort of 4,073 participants, 5.9% developed heart failure, and 19% developed atrial fibrillation during follow-up.
Cox regression modeling assessed associations of volume ratios with cardiac events, adjusting for traditional risk factors.
This analysis highlights the predictive value of chamber volume ratios, indicating potential for early intervention in cardiac health.
