BMI, body mass index; LVEDD, left ventricular end diastolic diameter; LVEF, left ventricular ejection fraction; Anti-M2-R, autoantibodies against M2-muscarinic acetylcholine receptors. One-way ANOVA and the unpaired Student’s two-tailed t-test were performed among the three groups or between two groups. .
