The values represent the number (percentage in parentheses) of study subjects or mean ± SD. Student's t‐test and chi‐square test were used for statistics.
AF = atrial fibrillation; BMI = weight (kg) divided by height (m)2; HR = heart rate; LVEDD = left ventricular end diastolic diameter; LVEF = left ventricular ejection fraction.
