Dear Editor,

The study by Nascimento et al. provides information on the effects of physical training and the Heart Rate Variability (HRV) in patients with Chagasic heart disease. Changes in HRV were not observed after exercise intervention, but the intervention group showed improved functional capacity after 12 weeks of the study.

Changes in the autonomic nervous system are observed in Chagasic heart disease and although physical training can improve HRV in other forms of heart failure, evidence suggests it does not happen in Chagasic heart disease, corroborating findings by Nascimento et al. However, in addition to the relatively few studies on the subject, which limits further conclusions, questions related to exercise prescription in the present study need to be better clarified.
