- normal values:
- men: less than 174 Units/liter
- women: less than 140 Units/liter
- isoenzymes: MM 100%, MB (cardiac) and BB (brain) normally comprise 0%;
- abnormal values:
- myocardial infarct
- CPK levels begin to rise 4-6 hours after MI has started and reaches its peack values within 30 hrs;
- look for an elevation of the CPK MB isoenzymes at 4-6 hours (in MI the CPK MB is more than 5% of total CPK);
- post surgical elevation: there will be an elevation of the CPK level, but the CPK MB percentage should be close to 0;
- Troponin I and T:
- these are cardiac specific muscle proteins which are elevated with cardiac muscle damage;
- may also be elevated with pulmonary embolism
