    Main Results:

    • Creatine phosphokinase is a primary enzyme for myocardial infarction diagnosis.
    • Limitations of CPK include technical factors and non-cardiac causes of elevation.
    • Isoenzymes of CPK and LDH enhance diagnostic specificity.
    • Enzymes are beneficial for prognosis assessment and guiding therapy.

    Conclusions:

    • Enzyme analysis, particularly serial testing and isoenzyme evaluation, is crucial for myocardial infarction diagnosis.
    • Understanding enzyme limitations is essential for accurate interpretation.
    • Enzyme data aids in predicting patient outcomes and optimizing treatment strategies.
