Having had myocarditis as a child may have certain effects later on. Although the disease itself can be cured, the damage to the heart muscle is irreversible, and many people may experience panic attacks, palpitations, or discomfort in the precordial region after a cold or overexertion as adults, called myocarditis sequelae. In addition, in patients with myocarditis, a poor recovery may lead to heart failure, and the patient may suffer from dyspnea, shortness of breath, and shortness of breath. If a patient is diagnosed with myocarditis, then it is important to actively give systematic diagnostic treatment. During the first three months of the disease, activities should be minimized, and absolute bed rest is preferable for the first month to avoid inducing heart failure.
