Key result
Epicardial adipose tissue locations demonstrated excellent agreement with high dominant frequency sites (κ=0.77; 95% CI, 0.71-0.82) but poor agreement with complicated fractionated electrogram sites.
Population
34 patients with atrial fibrillation (16 with paroxysmal AF and 18 with persistent AF)

EAT site associations with DF/CFAE in AF warrant caution against targeting; leaves open causal role and outcome benefit.
Observational (n=34)
Effect estimate: κ=0.77 (95% CI 0.71-0.82)
Epicardial adipose tissue locations strongly correlate with high dominant frequency sites during atrial fibrillation, suggesting EAT may play a role in AF maintenance.
Nagashima et al. (2012) conducted an observational in Atrial fibrillation (n=34). Epicardial adipose tissue (EAT) was evaluated on Agreement between locations of epicardial adipose tissue and high dominant frequency sites (κ=0.77, 95% CI 0.71-0.82). Epicardial adipose tissue locations demonstrated excellent agreement with high dominant frequency sites (κ=0.77; 95% CI, 0.71-0.82) but poor agreement with complicated fractionated electrogram sites.
