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). This evidence concerns the gene NPPB and myocardial infarction.
