When expression of the FTO gene was employed as the dependent variable, three models were computed, indicating FBG (β=-0.168, p=0.011), expression of the LPL gene (β=-0.157, p=0.016), and cTn (β=0.153, p=0.018) as important determinants of AF subjects suffering with MetS. This evidence concerns the gene FTO and atrial fibrillation.
