The severity of myocardial ischemia in children depends on the cause or causes of the myocardial ischemia. If the myocardial ischemia is caused by anemia or thyroid abnormalities, the condition is often not very serious and will improve or be cured by combining the correction of the anemia or thyroid abnormalities. If the myocardial ischemia is caused by viral myocarditis, the condition is relatively serious. If viral myocarditis does not recover well, it can turn into dilated cardiomyopathy and the patient may experience heart failure, which must be actively diagnosed and treated. In addition, sometimes there are inflammatory infections and fever in children, which may cause myocardial ischemia secondary to this condition, which is relatively not very serious inflammation, infection control, myocardial ischemia will naturally be improved.
