What is the difference between isoenzyme and myocardial zymogram?

According to the query medical network, the enzymes they detect are different.

1, isoenzymes refer to alanine aminotransferase (ALT) and aspartate aminotransferase (AST) in the liver, which are also released into the blood when myocardial injury occurs. Therefore, isozyme examination can help doctors diagnose myocardial injury. However, isoenzyme is also affected by other factors, such as liver disease, which needs to be comprehensively judged in combination with other examination results.

2. The myocardial zymogram includes creatine kinase (CK), creatine kinase isoenzyme (CK MB) and myoglobin (MYO), among which CK MB is a sensitive index of myocardial injury. Myocardial enzyme spectrum examination can judge the degree and scope of myocardial injury more accurately, and it is one of the commonly used diagnostic methods of myocardial injury.
