Viral myocarditis is rare, and there are a number of known causative pathogens. According to Patient UK, a leading health information organisation these viruses include Coxsackie B and adenovirus, influenza (flu), Epstein-Barr, rubella, mumps, measles, yellow fever, dengue, polio, and the viruses that cause hepatitis A and C.
Viral myocarditis can attack anyone at anytime and most cases are not infectious. That is, you can't catch it from another person. On many occasions the body is able to deal with the viral threat and the symptoms resolve themselves within a week. However, sometimes the inflammation remains, long after the pathogens have been dispatched. This could be caused by an over active immune system that prolongs the inflammation. Some of the viral infection symptoms of viral myocarditis include: - shortness of breath, chest pain, fatigue heart palpitations, leg swelling, irregular heartbeat, and fainting.
Treatment will depend on the severity of symptoms; bed rest is usually prescribed and in most cases the viral infection will clear up of its own accord. However, in rare situations there are complications and the symptoms will worsen and an individual will need further treatments. Again, depending on the severity of these symptoms the range of treatments can include; - steroids to reduce the inflammation, pacemaker, or heart transplant (in the most serious cases).
