Omran et al. [40] presented that MPO was a more efficient marker compared to creatine kinase (CK) MB and Troponin I (cTn I) to discriminate AMI from non-coronary chest pain patients, stable angina patients, and unstable angina patients within 0–6 h after the onset of AMI. The gene discussed is TNNI3; the disease is angina pectoris.
