The life expectancy after diagnosis of myocarditis is 50% at 10 years and only 50% at 4 years after diagnosis of DCM (Grzybowski et al., 1996; Gupta et al., 2008). Over 20% of sudden deaths among young adults, the military, and athletes are due to myocarditis (Gupta et al., 2008). Similar to coronary artery disease and HF, myocarditis and DCM occur more frequently in men than women (Cooper, 2009; Roger et al., 2011).
