Myocarditis or inflammatory cardiomyopathy is inflammation of heart muscle (myocardium).Myocarditis is most often due to infection by common viruses such as parvovirus B19 less commonly nonviral pathogens such as Borrelia burgdorferi (Lyme disease) or Trypanosoma cruzi or as a hypersensitivity response to drugs.The definition of myocarditis varies but the central feature is an infection of the heart with an inflammatory infiltrate and damage to the heart muscle without the blockage of coronary arteries that define a heart attack (myocardial infarction) or other common noninfectious causes.
