The levels of I-FABP were significantly higher in the participants with established CHD or significant stenosis (> 50%) compared to those with normal coronary arteries or nonsignificant stenosis (< 50%), median 1.67 ng/ml (IQR 1.02–2.32) versus 1.09 ng/ml (IQR 0.82–1.58), (p = 0.003). Here, FABP2 is linked to coronary artery disorder.
