HR, hazard ratio; AF, atrial fibrillation; TIA, transient ischemic attack; LA, left atrium; LV; left ventricle; E/Em, mitral inflow velocity/mitral annulus tissue velocity; LVEDD, left ventricular end diastolic dimension; CT, computed tomography; CTI, cavotricuspid isthmus; PV, pulmonary vein; POBI, posterior box isolation; AAD, antiarrhythmic drugs; HPSD, high power short duration. The bold values mean statistical significance such as p-value < 0.05.
