Study Notes
Creatine Kinase Isoenzymes
- CK-MB is the isoenzyme primarily associated with cardiac muscle.
- It is a specific marker for detecting myocardial injury or infarction.
Importance of CK-MB Measurement
- Measuring CK-MB levels aids in the diagnosis of acute coronary syndromes.
- Elevated CK-MB indicates damage to cardiac tissue, helping differentiate cardiac from non-cardiac causes of chest pain.
Situations Resulting in Increased CK-MB Levels
- Post-myocardial infarction (heart attack) is a common scenario where CK-MB levels rise.
- Other situations include cardiac surgery, severe myocardial ischemia, and myocarditis.
Location Differences of CK Isoenzymes
- CK-MB is found predominantly in the heart, while CK-MM is related to skeletal muscle and CK-BB is linked to brain tissue.
- This distribution makes CK-MB a targeted biomarker for heart-related damage.
Conditions with No CK-MB Elevation
- Conditions such as skeletal muscle injury or rhabdomyolysis typically do not result in elevated CK-MB levels, as they primarily increase CK-MM instead.
