Key result
Higher Cardio-Ankle Vascular Index (CAVI) was significantly correlated with increased left atrial volume index (r=0.297) and right atrial volume index (r=0.252), indicating a close association between arterial stiffness and biatrial remodeling in atrial fibrillation.
Why the study?
The impact of arterial stiffness on the process of atrial remodeling in association with AF had not been fully evaluated.
Does arterial stiffness measured by CAVI correlate with biatrial remodeling in patients with atrial fibrillation?

Effect estimate: r = 0.297
p-value: p=0.001
Arterial stiffness, as measured by CAVI, is independently associated with structural and electrical biatrial remodeling in patients with atrial fibrillation.
Nakamura et al. (2020) conducted a cross-sectional in Atrial Fibrillation (n=213). Cardio-ankle vascular index (CAVI) vs. Lower/Normal CAVI was evaluated on Correlation between CAVI and left atrial volume index (LAVI) (r = 0.297, p=0.001). Higher Cardio-Ankle Vascular Index (CAVI) was significantly correlated with increased left atrial volume index (r=0.297) and right atrial volume index (r=0.252), indicating a close association between arterial stiffness and biatrial remodeling in atrial fibrillation.
