Myocarditis often has a self-limiting course, and viral infection is a common cause of myocarditis. Currently, there is no specific treatment for viral myocarditis. Treatments are divided into two main categories: general treatment, primarily consisting of rest. Generally, patients should rest in bed for more than three months, while also paying attention to their diet by eating easily digestible foods rich in vitamins and proteins. The second category is drug treatment, which mainly supports heart function. In cases of heart failure, diuretics, vasodilators, and ACE inhibitors should be administered. For arrhythmias, anti-arrhythmic treatment is necessary. If viral myocarditis is confirmed, antiviral treatment should be given. Additionally, drugs that enhance myocardial metabolism, such as cyclic adenosine monophosphate, coenzyme A, or adenosine triphosphate, should also be used. (Specific medication use should be conducted under the guidance of a doctor.)
