3.3 Total epicardial fat volume
3 studies including 309 patients were involved in EAT volume. The
comparison of total EAT volume between AFACS vs non-AFACS showed an SMD
of 0.56 ml [95% confidence interval (CI) = 0.02, 1.10, P=0.04],
indicating that EAT volume was higher in AF occurrence patients.
Apparent significant heterogeneity was found among the studies’ results
(I2 = 76%, P = 0.01) (Fig. 2-A).
