Statistically significant variables in the baseline data comparison between the HF group and the HF-AF group were taken as independent variables, and the variables with no statistical difference are not included in the table. HF, heart failure; LVEF, left ventricular ejection fraction; LVD, left ventricular end-diastolic diameter; LAD, left atrial diameter; sST2, soluble suppression of tumorigenicity 2; AF, atrial fibrillation.
