In laboratory results, MI patients with MACE in pre-CABG had a higher CK-MB level (P < 0.05), a conventional risk factor of AMI, as compared to those without MACE, but no significant differences in other myocardial infarction-related risk factors including NT-pro-BNP, cTnI, and Myoglobin, as well as relevant biochemical parameters including LDH and creatinine were observed in these subjects with or without MACE (Table 1). The gene discussed is TNNI3; the disease is myocardial infarction.
