Myocardial enzyme examination is currently mainly used to check and judge whether there is myocardial injury, as well as muscle injury examination. Among them, myocardial injury is mainly related to myocarditis and acute myocardial infarction. When myocarditis and myocardial infarction occur, the progressive increase of myocardial enzymes will occur due to myocardial damage and necrosis. The symptoms of patients often include chest pain, shortness of breath, and panic. However, diseases related to muscle injury, such as progressive muscular dystrophy, often lead to a significant increase in myocardial enzymes. In addition, other factors, such as drugs, can also cause the rise of myocardial enzymes. Currently, statins are the most common drugs. Hypokalemia can also cause an increase in myocardial enzymes.
