Answer

In the past, different cardiac biomarkers have been used to evaluate patients with suspected acute myocardial infarction (MI) (acute coronary syndrome [ACS] and ST-elevation MI [STEMI]). The cardiac-specific troponins I and T, creatine kinase (CK), the MB isoenzyme of creatine kinase (CK-MB), and myoglobin have been used as surrogates for myocardial necrosis.
