How long does troponin I, creatine kinase (CK) and myoglobin remain detectable after a myocardial infarction? Cardiac enzymes (a.k.a. cardiac biomarkers) include myoglobin, troponin and creatine ...

Cardiac enzymes ― also known as cardiac biomarkers ― include myoglobin, troponin and creatine kinase. Historically, lactate dehydrogenase, or LDH, was also used but is non-specific.

For example, some diseases that affect the muscles may not cause elevated CK levels in the blood. Most healthcare providers now test for elevated cardiac troponin levels, another protein ...

Blood CK-MB may be derived from tissues other than cardiomyocytes and have lower specificity for cardiac tissue than troponins. However, in a recent study including 19 non-ST elevation OHCA ...
