FGF21 and coronary artery disorder: Lee et al. studied the relation between serum FGF21 and CAD diagnosis according to computed tomography findings and found that serum FGF21 level was significantly correlated with serum TG, LDL-c, HOMA-IR and the occurrence of MS; however, no relationship was found between serum FGF21 level and CAD diagnosed by computed tomography [19].
