Abstract
Introduction: Chronic cardiomyopathy is a fatal form of the Chagas disease without specific treatment. It is a frequent type of dilated cardiomyopathy usually not recognized by the health team in non-endemic areas. The cases presented here represent the first autochthonous cases of the disease in Coahuila, Mexico.
Case Series: Two cases of dilated cardiomyopathy with positive antibodies to Trypanosoma cruzi are presented, one of them with progressive heart failure and another with conduction disorders.
Conclusion: Even in areas of low endemicity, all cases of dilated cardiomyopathy, Chagas disease should be rule out as one of the etiologies.

Keywords: Dilated cardiomyopathy, Chronic cardiomyopathy, Chagas disease, Trypanosoma cruzi
