Introduction
Under normal circumstances, the normal range for creatine kinase isoenzyme (CK-MB) is generally 0–25 U/L. A level of 57 U/L has exceeded the normal range. Whether this is serious depends on the specific circumstances. If the elevation in CK-MB is caused by physiological factors, it may not be serious. However, if the elevation is due to pathological factors, it may be more severe.
Under normal circumstances, the reference range for creatine kinase isoenzyme (CK-MB) is generally 0-25 U/L. A level of 57 U/L has exceeded the normal range. Whether this is serious depends on the specific circumstances. If the elevated CK-MB is caused by physiological factors, it may not be serious. However, if it is caused by pathological factors, the condition might be more severe.
Regarding physiological factors, intense physical exercise can cause a certain degree of muscle tissue damage, leading to the release of CK-MB into the bloodstream and thus increasing the enzyme's activity in blood. Usually, after a period of rest, the enzyme activity will gradually return to normal levels, and this condition is generally not serious. During growth and development in children and adolescents, rapid skeletal muscle growth may lead to physiological elevation of CK-MB. This condition is also usually not serious, but regular monitoring is needed to observe the trend of changes.
Concerning pathological factors, when viral infections affect myocardial cells, an inflammatory reaction in the heart muscle can occur, causing damage to myocardial cells and an increase in CK-MB levels. This may lead to complications such as arrhythmia and myocardial scarring, indicating a more serious condition. It is recommended to follow medical advice and use medications such as furosemide tablets, isosorbide mononitrate sustained-release tablets, and compound captopril tablets for treatment. Additionally, cerebrovascular accidents such as cerebral infarction and cerebral hemorrhage may cause the release of neuron-specific enolase and other enzymes due to brain tissue damage, and may also be accompanied by a mild increase in CK-MB levels. If not treated promptly, the condition may result in complications such as hemiplegia and speech disorders.
If CK-MB levels are higher than normal, it is recommended to undergo further examinations to determine the underlying cause and receive timely treatment accordingly.
