Patient's question:
A one-year-old baby has a fever. Urine lymphocyte count is high, suggesting a viral infection, but creatine kinase is high, reaching 207, which is above the normal range. After fever reduction, everything returns to normal. Will there be myocarditis?Doctor's answer:
Myocarditis refers to inflammatory lesions of the heart muscle caused by various factors, which may manifest as palpitations, blackouts, dizziness, chest tightness, chest pain, or severe myocardial damage or heart failure. Generally, a fever can lead to a decrease in creatine kinase, which is often associated with viral infections. This is the myocardial damage caused by viral infections. After the body temperature returns to normal, creatine kinase can return to normal, so it is not myocarditis.
