This heart indicator often appears abnormal, but it may not be a heart disease

Many patients have been shocked by this test result:

Myocardial enzymes elevated !

I checked online and found that elevated myocardial enzymes could be a sign of heart disease or even acute myocardial infarction. But I didn't feel any discomfort, so what was going on?

Because elevated myocardial enzymes do not necessarily mean heart disease.

Myocardial enzymes include creatine kinase and lactate dehydrogenase, which are released from myocardial cells into the blood when the myocardium is damaged, causing the test values ​​to increase significantly. In the past, they have been an important basis for judging myocardial damage or even acute myocardial infarction.

However, myocardial enzymes are not only present in the heart, but also in skeletal muscle, kidney, liver and other organs. When these organs are damaged by hepatitis, muscle injury or strenuous exercise, myocardial enzymes will also increase. Therefore, doctors will not directly diagnose heart disease when they find elevated myocardial enzymes, but will combine the patient's symptoms, medical history and further examinations.

With the development of testing technology, myocardial enzymes have gradually been replaced by more accurate cardiac indicators such as troponin.

I am Dr. Zhang from the Department of Cardiology. Follow me to learn more about heart disease. Goodbye!
