Final answer:
Creatine phosphokinase (CPK), lactate dehydrogenase (LDH), and cardiac troponin are laboratory markers of acute cardiac damage or injury.
Step-by-step explanation:
Acute cardiac damage or injury can be detected by several laboratory markers. These markers include:
- Creatine phosphokinase (CPK): This enzyme is the marker for diagnosing myocardial infarction or heart attack. CPK increases in the blood plasma shortly after a heart attack.
- Lactate dehydrogenase (LDH): LDH is an enzyme that is released into the blood when there is damage to heart tissue. Elevated levels of LDH can indicate myocardial infarction.
- Cardiac troponin: This protein is released by damaged cardiac muscle cells and is another marker for myocardial infarction.
