Myocarditis is an inflammatory disease of the heart muscle that may heal on its own if left untreated, or it may cause damage to the heart muscle and even trigger heart failure, which can be life-threatening. Myocarditis can be divided into acute myocarditis, chronic prolonged myocarditis, and fulminant myocarditis, and the outcome varies with different types of myocarditis.1. Acute myocarditis: Acute myocarditis tends to be less symptomatic, and this type of myocarditis is sometimes not easily detectable, and after detection, patients may show symptoms of a cold. This type of myocarditis, the prognosis is often better than fulminant myocarditis, some patients can even be cured without drugs, and generally does not endanger the life of the patient. The actual fact is that you can find a lot of people who are not able to get a good deal on a lot of things. In this process, myocardial fibrosis and myocardial cell apoptosis occur, leading to myocardial remodeling, and with the extension of time, patients with this type of myocarditis progress to cardiomyopathy, which may endanger the patient’s life; 3. fulminant myocarditis: for patients with fulminant myocarditis, it is a critical condition, and if not treated, patients may develop within 24-48h of onset If left untreated, patients may develop malignant arrhythmias, severe heart failure, which can lead to cardiogenic shock and other conditions. Therefore, it is recommended that patients actively take treatment to avoid shock or even death within a short period of time.
