> While we often associate cardiovascular conditions with elderly populations, myocarditis can affect anyone, including young adults, children and infants. In fact, it most often affects otherwise healthy, young, athletic types with the high-risk population being those of ages from puberty through their early 30’s, affecting males twice as often as females. Myocarditis is the 3rd leading cause of Sudden Death in children and young adults.
