Anatomia patológica de corações de chagásicos assintomáticos falecidos de modo violento

With the purpose of better knowledge of the indeterminate form of Chagas's disease the authors carried out a systematized anatomopathological study of thirty hearts from symptomatic chagasics who had a violent death. In this specific form of the trypanosomiasis cruzi the hearts show lesions of the same nature but much less intense as those observed in chronic chagasics who had a sudden death or died after cardiac failure. Based on theses findings and on data from literature, we conclude that chagasic infection without a cardiac inflammatory process, if it occurs, is very rarely only. Also some comments are made upon the meaning of the lesions observed in the intra-cardiac autonomic nervous system, in the conduction system and on the formal origin of the human chronic chagasic carditis.
