Blood myoglobin >100μg/L or urine myoglobin >1000μg/L are cause for concern. If acute myocardial injury, skeletal muscle injury, or kidney injury occurs, life-threatening conditions are likely to occur. Normal blood myoglobin range: 20~80μg/L for men, 10~70μg/L for women. myoglobin is found only in human skeletal muscle tissue and cardiac muscle, and elevated myoglobin often suggests damage to the heart muscle. When elevated myoglobin is accompanied by persistent chest pain, it suggests acute myocardial infarction, acute myocarditis, etc., which is usually more serious. In addition, other systemic diseases, such as severe infections, severe shock, surgical trauma, renal insufficiency, renal failure and other conditions of the population, can also lead to elevated myoglobin, when the patient’s renal function should be related to the treatment. Specific should be combined with blood test, electrocardiogram examination, patient symptoms, primary disease and other comprehensive consideration. It is recommended to go to the hospital for diagnosis and treatment in time.
