TNNI3 and myocardial infarction: Furthermore, logistic regression analysis also demonstrated that both serum FGF21 and CK-MB levels at post-CABG were significantly associated with the incidence of MACE in these 265 MI patients undergone CAGB after adjusting by age, gender, history of MI, history of drinking, cTnI, smoking, hyperlipidemia, and CK-MB (p < 0.05, respectively), suggesting that both serum FGF21 and CK-MB levels at post-CABG are related to the incidence of MACE in patients with MI after CABG surgery (Table 3).
