Any admission within 30 or 90\u00a0days of index admission was considered a readmission. Cox proportional hazard regression was used to adjust for confounders. The primary outcomes were 30\u2010 and 90\u2010day readmissions and the secondary outcome was\n AF<\/jats:styled-content>\n recurrence. In total, 1\u00a0128\u00a0372 patients with\n AF<\/jats:styled-content>\n were identified from January 1, 2010 to September 30, 2014. Of which 37\u00a0360 (3.3%) underwent\n CA<\/jats:styled-content>\n . Patients aged \u226565\u00a0years and female sex were less likely to receive\n CA<\/jats:styled-content>\n for\n AF<\/jats:styled-content>\n . Overall, 10.9% and 16.5% of\n CA<\/jats:styled-content>\n patients were readmitted within 30 and 90\u00a0days post\u2010CA, respectively. Most common causes of readmissions were arrhythmia (\n AF<\/jats:styled-content>\n , atrial flutter), heart failure, pulmonary causes (pneumonia, chronic obstructive pulmonary disease) and bleeding complications (gastrointestinal bleed, intracranial hemorrhage). Patients with diabetes mellitus, heart failure, coronary artery disease (\n CAD<\/jats:styled-content>\n ), chronic pulmonary and kidney disease, prior stroke\/transient ischemic attack (TIA), female sex, length of stay \u22652 and disposition to the facility were prone to higher 30\u2010 and 90\u2010day readmissions post\n \u2010CA<\/jats:styled-content>\n . Predictors of increase in\n AF<\/jats:styled-content>\n recurrence post\u2010\n CA<\/jats:styled-content>\n were female sex, diabetes mellitus,\u00a0chronic pulmonary disease, and length of stay \u22652.
