[Chagas' disease in Mexico. Report of 5 proven cases].

Seroepidemiologic studies demonstrated that American Trypanosomiasis is highly prevalent among rural communities in Mexico. However, Chagas' disease seems to be a rarity. That could be a wrong concept. In just a few months 5 patients with epidemiological, clinical and immunologic evidence for Chagasic miocardiopathy or miocarditis were identified in our Institution. Their cardiologic findings have been discussed, as well as diagnostic approaches in different stages of the disease.
