TTR: Western Blot – 1.5-fold lower in CAD versus control, P < .023,ELISA – 1.61-fold lower in CAD vs. control, P < .0001,FACS – 2-fold lower in CAD vs. control, protein expression: 5.92% vs. 13.13%Other biomarkers: serotransferrin, talin-1, alpha-2HS glycoprotein, transthyretin (TTR), fibrinogen-α chain. Here, TTR is linked to coronary artery disorder.
