Brief Summary

Background: Chagasic myocardiopathy caused by the protozoa Trypanosoma cruzi has been the principal cause of cardiac death in Latin America. Without any trypanocidal therapeutic intervention, infected subjects can pass from the indeterminate to the cardiac form with heart dysfunction. Our group has studied the role and the effect of the supplementation with the essential micronutrient selenium (Se) on T. cruzi infection, and the investigators have verified that:

  1. 1.low Se levels is related to the severity of the myocardiopathy in chagasic patients
  2. 2.adequate Se diet is essential for mice survival at the acute phase of the experimental T. cruzi infection
  3. 3.Se supplementation prevented the myocardial lesions at the acute phase in mice. From these findings and considering that Se supplementation was able to prevent Keshan cardiopathy, to revert electrocardiographic and echocardiographic alterations in patients nourished by parenteral route, and reduced re-infarction and cardiac deaths from acute myocardial infarction; the investigators purpose to investigate if Se treatment via oral route, is able to impair the progress of heart dysfunction in chagasic patients expressed by the study of progression rate and by the comparison of the means of ventricular ejection fraction.
