Final answer:
Cardiac enzymes are used to monitor cardiac damage, especially after a heart attack. They indicate heart tissue damage and help in assessing treatment effectiveness.
Step-by-step explanation:
Cardiac enzymes assist with monitoring cardiac damage. They are released into the blood when heart tissue damage occurs, such as during a myocardial infarction (heart attack). Specific enzymes, like LDH1 and creatine phosphokinase (CPK), elevate in the blood serum reflecting the extent of heart damage. CPK is particularly significant as it is often the first enzyme to increase following a heart attack. Monitoring these enzymes helps medical professionals determine the effects of a heart attack, assess the effectiveness of treatment plans, and evaluate heart function.
