Age, male, HT, DM, CHD, AST, Urea, UA, and UHR in the AF group were significantly higher than those in the non-AF group, while LYM, ALB, TC, HDL-C, and LDL-C were lower than those in the non-AF group, with statistical significance (P < 0.05) (Table 1). This evidence concerns the gene ALB and atrial fibrillation.
