Key result
In patients with persistent atrial fibrillation, arterial stiffness measured by CAVI was independently associated with left atrial diameter immediately after successful external cardioversion (β = 1.92).
Cross-Sectional (n=33)
No
Effect estimate: β = 1.92 (95% CI 0.56-3.27)
p-value: p=0.007
In patients with persistent atrial fibrillation, arterial stiffness is independently associated with left atrial size immediately after external cardioversion, suggesting a vascular component in arrhythmia maintenance.

Hypothesis-generating for vascular contribution to AF substrate; prospective studies needed before considering stiffness-targeted interventions.
Fumagalli et al. (2013) conducted a cross-sectional in Persistent atrial fibrillation (n=33). Arterial stiffness (Cardio-Ankle Vascular Index) was evaluated on Predictors of left atrial diameter (LAD) (β = 1.92, 95% CI 0.56-3.27, p=0.007). In patients with persistent atrial fibrillation, arterial stiffness measured by CAVI was independently associated with left atrial diameter immediately after successful external cardioversion (β = 1.92).
