Heart attack will increase myocardial enzymes?

Myocardial infarction generally leads to elevated myocardial enzymes, but elevated myocardial enzymes do not necessarily mean myocardial infarction. It should be judged comprehensively in combination with clinical symptoms and other examination results. Myocardial infarction generally leads to elevated myocardial enzymes. Myocardial enzyme is a variety of enzymes existing in myocardial cells. When myocardial infarction occurs, myocardial cells will be damaged and necrotic, and myocardial enzymes will be released into the blood, resulting in an increase in serum myocardial enzyme levels. Myocardial enzyme examination is one of the common methods to diagnose myocardial infarction, among which the common myocardial enzymes include creatine kinase (CK) and creatine kinase isoenzyme (CK-MB), aspartate aminotransferase (AST), lactate dehydrogenase (LDH), etc. Generally speaking, after myocardial infarction, these myocardial enzymes will increase within a few hours after symptoms appear, peak at about 24 - 72 hours, and then gradually decrease. It should be noted that elevated myocardial enzymes do not necessarily mean myocardial infarction. Other diseases such as myocarditis, cardiomyopathy, heart failure, etc. may also lead to elevated myocardial enzymes. In addition, some drugs, strenuous exercise, muscle damage and other factors may also affect myocardial enzyme levels. Therefore, elevated myocardial enzymes need to be combined with clinical symptoms, ECG and other test results for comprehensive judgment. For patients suspected of myocardial infarction, doctors usually perform myocardial enzymes, ECG, cardiac imaging, etc. to confirm the diagnosis and take appropriate treatment measures. Treatment methods include thrombolytic therapy, interventional therapy, coronary artery bypass grafting, etc., aiming to restore myocardial blood supply as soon as possible, reduce myocardial damage, and reduce mortality and complications. In short, elevated myocardial enzymes are an important manifestation of myocardial infarction, but not the only basis for the diagnosis of myocardial infarction. If chest pain, dyspnea and other suspected myocardial infarction symptoms, should seek medical attention in time, relevant examination and treatment. At the same time, for people with high risk factors for cardiovascular disease, such as hypertension, hyperlipidemia, diabetes, smoking, etc., risk factors should be actively controlled and physical examination should be carried out regularly so as to detect and treat cardiovascular disease early.
