Myocarditis refers to the inflammatory disease of the myocardium. Symptoms of myocarditis can vary greatly; some individuals may exhibit no symptoms, while others may experience cardiogenic shock or sudden death. Currently, there are no specific treatments for myocarditis. Patients should avoid exertion, rest appropriately, and receive nutritional support. It is advised to encourage patients to consume a diet that is easy to digest and rich in vitamins and proteins. For asymptomatic patients, attention should be paid to rest and nutrition. However, in cases where there is left ventricular dysfunction, treatment primarily supports these symptoms. For instance, in the event of heart failure, diuretics, vasodilators, or ACE inhibitors might be administered. Most cases of myocarditis are self-limiting, but there are occasional instances of fulminant or severe myocarditis, which should be taken seriously. Therefore, the treatability of myocarditis is related to the extent and location of the pathological changes. (Please use medications under the guidance of a doctor.)
