The symptoms of recovery from myocarditis are related to the degree of myocardial damage caused by the acute phase of myocarditis. If the patient’s primary myocarditis is relatively mild and is treated regularly, the symptoms of recovery can be mild, leaving only weakness and decreased activity tolerance. With further recovery, the symptoms may return to normal. If the patient’s primary myocarditis disease is severe or is not treated properly, resulting in extensive myocardial damage or even necrosis. Patients can develop more severe symptoms, which mainly include chest pain, chest tightness, and symptoms of heart failure such as active shortness of breath. Since myocardium is a non-renewable cell, once necrosis occurs, it cannot be completely cured. Moderate physical exercise is required in daily life to enhance the compensatory capacity of the remaining myocardium to relieve symptoms.
