Patients with myocarditis should avoid exercising. Myocarditis is caused by acute or chronic damage to the myocardium due to viral infections. After contracting myocarditis, patients may experience palpitations and shortness of breath; severe cases can lead to heart failure, arrhythmias, and cardiogenic shock. For myocarditis, early diagnosis and treatment are crucial for recovery. Patients with myocarditis must rest in bed, minimize physical activity, consume easily digestible foods, and eat a variety of vitamins and minerals through vegetables and fruits to maintain regular bowel movements. Effective antiviral drugs and treatments that nourish the myocardium should be used to help the damaged myocardium recover as soon as possible.
