TNNT2 and neuromuscular disease: The two biomarkers are different to a certain extent: the half-life of cTnT is 30 min longer than that of cTnl; cTnl is less affected by renal function compared to cTnT; cTnI is more specific to cardiac tissue than cTnT; and cTnT is also seen in neuromuscular diseases in addition to myocardial injury.
