Mild myocarditis usually resolves on its own. Myocarditis is caused by inflammatory lesions in the heart muscle due to viral infections, medications, poisons, vasculitis, and other factors. Symptoms such as panic, chest pain, and shortness of breath usually occur. If the symptoms of mild myocarditis are relatively mild, there is no cardiogenic shock, heart failure and other complications, and due to the self-limiting nature, most of them can be cured after rest or symptomatic treatment. If mild myocarditis does not pay attention to the occurrence of myocarditis, but still over-exercise, exertion, or has been complicated by heart failure, cardiogenic shock, and serious dyspnea, fainting, chest pain and other symptoms, then it can not be self-cured. Usually after the diagnosis of mild myocarditis, it is recommended to consult a doctor in time for treatment. Don’t leave it to chance to avoid delaying the best treatment time.
