Under normal circumstances, myocardial enzymes that return to normal and are within the normal range for three consecutive weeks of testing indicate a high probability of gradual improvement of myocarditis. However, the diagnosis of whether myocarditis is improving soon is also based on the patient’s clinical symptoms, clinical manifestations and the performance of other ancillary tests. For example, if the patient has no fever, no significant chest tightness or shortness of breath, no significant arrhythmia, and if the patient has no significant increase in serum troponin I, troponin T, or creatine kinase isoenzyme within three weeks of the electrocardiogram, 24-hour ambulatory electrocardiogram, and if the echocardiogram shows that the enlarged heart chambers and abnormal ventricular wall activity are gradually returning to normal, then it is possible to prove that myocarditis is getting better. The condition.
