LUGO ESPINOZA, Victor Cesar  e  ARAUJO RIOS, Raúl. Acute on fuzzy myocarditis, dilated cardiomyopathy caused by trypanosoma cruzi and detection by nuclear medicine. Rev Cient Cienc Méd [online]. 2013, vol.16, n.2, pp.37-39. ISSN 1817-7433.

Myocarditis is inflammation of the heart of multiple etiologies, is an insidious disease, usually asymptomatic and is a major cause of sudden death in young adults. In South America, Chagas disease is the leading cause of myocarditis and entails dilated cardiomyopathy which is considered as a clinical and pathophysiologic syndrome, characterized by myocardial dysfunction, of the myocardial electrical conduction and dilation of the heart chambers, which predisposes triggering heart failure and sudden death. The diagnosis of myocarditis is difficult, sometimes the clinic does not give us enough information and specific supplementary tests are invasive, so we highlight the use of nuclear methods in diagnosis. The heart scan is a heart radioisotope study with technetium pyrophosphate 99 m or Gallium 67; both are distributed specifically by inflamed heart tissue.
