*From chi-square (categorical) or Kruskal-Wallis test (continuous variables).
**Of the six patients with CES without AF at the emergency department, one had an echocardiographic finding of thrombus in the left atrium and five had developed AF during the hospital stay.
***Based on 88 (27, 20, 16, and 25) US echocardiographic examinations.
