Several imaging and biomarker tests have been shown to be able to detect the presence and determine the extent of clinically recognized MI measured by LGE including Q waves on a 12-lead electrocardiogram (ECG) (7), ejection fraction (8), strain parameters (9), high sensitivity troponin (hs-cTnT) (10), and amino-terminal probrain natriuretic peptide (NT-proBNP) (11). This evidence concerns the gene TNNT2 and myocardial infarction.
