For diagnosing AMI with recurrent angina, a cut-off value for cTnT (2.2 ng/mL) resulted with a sensitivity and NPV of 47.368% (95% CI: 24.447%-71.136%) and 80% (95% CI: 72.25%-86.004%), and a specificity and PPV of 97.561% (95% CI: 87.145%-99.938%) and 90% (95% CI: 55.085%-98.50%), respectively. This evidence concerns the gene TNNT2 and angina pectoris.
