Having myocarditis will not ruin your life. Patients can improve their quality of life and prolong their survival through active treatment. Myocarditis is variable in its acuteness and can be completely asymptomatic in mild cases, and only a few patients with fulminant myocarditis may suffer acute failure or sudden death. Myocarditis is a limited or diffuse inflammatory lesion of the myocardium and can be divided into two categories: infectious and non-infectious, with viral myocarditis being the most common. Most patients have a subclinical form and can be completely asymptomatic. Most patients have a good prognosis, with attention to avoiding exertion, limiting activity, and bed rest. Patients with left heart insufficiency are given supportive therapy and can be given a combination of diuretics, vasodilators, and beta-blockers, and patients can improve significantly. For those with tachyarrhythmia, antiarrhythmic drugs can be used for treatment. However, for fulminant myocarditis, the condition is severe and rapidly developing, and some patients develop heart failure and cardiogenic shock due to delayed treatment, with a poor prognosis. Some patients are treated promptly and can be cured by antiviral therapy, immunomodulatory therapy, and immunosorbent therapy, but some patients can be left with dilated cardiomyopathy. Therefore, patients with myocarditis should cooperate with treatment in a timely manner, pay attention to regular daily routine, increase exercise appropriately, and maintain balanced nutrition. At the same time to do their own protection, pay attention to warmth, to avoid the occurrence of infection aggravate the disease.
