Myocarditis consequence

Reduced cardiac output and impaired heart function.

Uncommon Viral Cause

Hepatitis A virus is not a common cause of myocarditis.

Most Common Cause

Viruses often trigger inflammation of the heart muscle.

Coxsackie-adenovirus receptor

This receptor facilitates viral entry into heart cells.
