The population comprised 60 AF patients and 130 patients without AF, including 75 with structural heart disease (SHD). DE was quantified using histogram thresholding, expressed in % of the wall. Regression analysis was performed to identify predictors of DE. Additionally, DE was registered on a template to study its distribution in subpopulations. In the total population, age, AF, and SHD were independently associated with DE. DE was increasingly observed from 11.1 \u00b1 4.7% in patients with no SHD nor AF, 18.8 \u00b1 7.8% in SHD and no AF history, 22.9 \u00b1 7.8% in paroxysmal AF, to 27.8 \u00b1 7.7% in persistent AF. Among non\u2010AF patients, age and SHD were independently associated with DE. Among AF patients, female gender and AF persistence were independently associated with DE.
