The three items of myocardial enzymes are mainly what to measure

The three items of myocardial enzymes mainly detect AST, LDH and CK, and their elevated levels indicate myocardial injury or infarction, but it needs to be judged comprehensively according to clinical symptoms, etc., and other factors may also cause their elevation. The three items of myocardial enzymes mainly detect the levels of myocardial enzymes, including aspartate aminotransferase (AST), lactic dehydrogenase (LDH) and creatine kinase (CK). These enzymes are released into the bloodstream when cardiac muscle cells are damaged, so elevated levels can indicate myocardial injury or infarct.AST: Widely found in heart muscle, liver, skeletal muscle and kidney tissues, especially in heart muscle."When myocardial infarction, AST can be 6 - 1-2 hours after the onset of elevated peak at 24 - 48 hours, the duration of 3 - 5 days. LDH: in the heart, skeletal muscle and kidney, red blood cells in the rich. When myocardial infarction, LDH can be 8 - 1-2 hours after the onset of elevated peak at 2 - 3 days, the duration of 1 - 2 weeks. CK: It is mainly found in skeletal muscle, heart muscle and brain tissues. When myocardial infarction occurs, CK may increase 3 - 8 hours after onset, with peak value at 1-2 - 24 hours and duration of 1 - 2 weeks. It should be noted that the detection results of three myocardial enzymes need to be comprehensively judged in combination with clinical symptoms, ECG and other examination results. In addition, some other factors may also cause elevated levels of myocardial enzymes, such as strenuous exercise, muscle injury, hepatitis, pneumonia, etc. Therefore, when interpreting the three results of myocardial enzymes, doctors need to consider the specific situation of the patient. For the population with high risk factors of myocardial infarction, such as the elderly, patients with hypertension, diabetes mellitus, hyperlipidemia, etc., regular detection of myocardial enzyme three contribute to early detection of myocardial infarction. If chest pain, chest tightness, dyspnea and other symptoms, should be timely medical treatment, ECG, myocardial enzyme and other examinations, so that early diagnosis and treatment."
