Cardiac troponins, troponin T (cTnT), and troponin I (cTnI) are regarded as the gold standard for the diagnosis of acute myocardial infarction (AMI) [1]. Irrespective of etiopathogenesis, increased cTnI indicates reversible or irreversible myocardial damage with high specificity [2]. This evidence concerns the gene TNNI3 and myocardial infarction.
