Overview
Developed Countries
Myocarditis is generally due to viral infections such as adenovirus, parvovirus B19, hepatitis C, and herpes virus 6 in developed countries.
Developing Countries
Myocarditis is generally due to HIV and rheumatic heart disease in developing countries.
Developed countries
Viral infections are the common cause for myocarditis in developed countries. Common virus involved are coxsackie B, . An article from 1995 reports that in Sweden the frequency of dilated cardiomyopathy secondary to myocarditis 7.5-10% per 100,000 annually with enteroviruses, and particularly the Coxsackie-B viruses being the most common cause[1]. Recent studies show that adenovirus, parvovirus B19, hepatitis C, and herpes virus 6 were the common causes for myocarditis[2][3].
The exact incidence of myocarditis is unknown. However, in series of routine autopsies, 1-9% of all patients had evidence of myocardial inflammation. In young adults, up to 20% of all cases of sudden death are due to myocarditis.
Myocarditis secondary to lyme disease should be suspected in people travelling to regions where it is endemic, particularly if they have conduction abnormalities of heart[4].
Developing countries
In South America, Chagas' disease (caused by Trypanosoma cruzi) is the main cause of myocarditis. Other causes in developing countries include rheumatic fever[5] and HIV infection.
Race
No difference in frequency of myocarditis is observed between various races.
The impact of Gender
Myocarditis is slightly more frequent among males than in females[6]. This may be due to natural hormonal protection among females.
