Since myocardial infarction is one of the most important factors leading to myocardial cell destruction, monitoring of cTnI blood concentrations is particularly important for the early detection of myocardial infarction (Ye et al., 2018; Lee et al., 2019; Sun et al., 2019a; Karimi-Maleh et al., 2020b, 2021). Here, TNNI3 is linked to myocardial infarction.
