We often see parents who are anxious about their children’s myocardial injury, but there is no need for that. The so-called myocardial injury refers to a temporary diagnosis of myocardial enzymes with varying degrees of elevation and a normal electrocardiogram, which is clinically insufficient to diagnose myocarditis, not a separate disease, often accompanied by other diseases, such as various upper and lower respiratory infections (colds, pneumonia, bronchitis), poisoning, etc. can cause myocardial injury, which is mostly a temporary phenomenon, with the original disease healing, most will heal in about 10 days. The heart muscle damage is temporary and will heal in about 10 days as the original disease heals, unlike myocarditis which requires two to three months or even more than six months of treatment. So parents don’t have to worry too much about this. We often see parents who are nervous about myocardial injury as myocarditis, and some primary care doctors are often confused about the difference between myocardial injury and myocarditis. The two are not difficult to separate, myocardial injury often only has increased cardiac enzymes and normal electrocardiograms, some doctors do not do electrocardiograms easily under the diagnosis of myocarditis is not rigorous, myocardial injury is often no clinical symptoms, only because of other diseases check myocardial enzymes were found, can be cured by short-term myocardial therapy; myocarditis, in addition to increased cardiac enzymes often have electrocardiogram abnormalities such as premature beats, will also In addition to increased myocardial enzymes, there are often ECG abnormalities, such as premature beats, and even cardiac insufficiency, often with weakness, chest tightness, chest pain and other discomfort, and myocardial enzymes are difficult to return to normal within a short period of time, often repeatedly, requiring a longer period of treatment such as myocardial nutrition to cure. The difference between myocardial injury and myocarditis is clear, so there is no need to worry too much about myocardial injury. It should be noted that the review of myocardial enzymes is best done after a week or so of curing a cold, pneumonia, etc., otherwise the results may be affected.
