What is the prognosis for myocarditis caused by a viral infection?

The vast majority of cases of viral myocarditis resolve completely, with the recovery of normal cardiac function. The prognosis is generally good, and most people make a full recovery. However, in rare cases, myocarditis can lead to serious complications, such as heart failure, arrhythmias, and sudden cardiac death. Recovery time varies depending on the severity of the infection and the individual's overall health. Mild myocarditis usually resolves within a few weeks, but more severe cases can take several months or even a year to fully heal.
