Note: Categorical data presented as count (percentage) and continuous data as mean (standard deviation) or median (Q1, Q3). AAD = anti-arrhythmic drug. AF = atrial fibrillation. BMI = body mass index (kg/m2). COPD = chronic obstructive pulmonary disease. NYHA = New York Heart Association Functional Classification. LVEF = left ventriuclar ejection fraction. OSA = obstructive sleep apnea. TIA = transient ischemic attack.
