Answer

Laboratory tests used in the diagnosis of MI include the following:

  • Cardiac biomarkers/enzymes: The American College of Cardiology/American Heart Association (ACC/AHA) and the European Society of Cardiology (ESC) guidelines recommend that cardiac biomarkers should be measured at presentation in patients with suspected MI, and that the only biomarker that is recommended to be used for the diagnosis of acute MI at this time is cardiac troponin due to its superior sensitivity and accuracy. [1, 2, 3, 4]

  • Troponin levels: Troponin is a contractile protein that normally is not found in serum; it is released only when myocardial necrosis occurs

  • Complete blood cell count

  • Comprehensive metabolic panel

  • Lipid profile
