Key result
The undetermined form of Chagas' disease has a benign course without prognostic implications, requiring only routine electrocardiogram monitoring and not precluding the ability to work.
The undetermined form of Chagas' disease has a benign course, requiring only routine ECG monitoring, and does not restrict patients' ability to work.
Supports ECG-only monitoring without work restrictions in undetermined Chagas; leaves open prospective validation in contemporary cohorts.
The undetermined form of Chagas' disease is diagnosed in asymptomatic subjects with a positive blood test for Chagas' disease, normal resting electrocardiogram, chest X-ray, barium esophageal and large bowel radiological studies. Other investigation methods are not recommended for identification of other organs damage lesions in this phase of the disease. When other methods of investigation were employed, cardiac and digestive abnormalities of small magnitude were detected without prognostic implications. These findings do not warrant frequent examinations of patients with undetermined form of the disease except for the electrocardiogram or if the patients report other clinical manifestations. The benign course of the disease does not preclude ability to work and the subjects should be considered apt for work in any profession.

Barretto et al. (1995) conducted a review in Chagas' disease (undetermined form). The undetermined form of Chagas' disease has a benign course without prognostic implications, requiring only routine electrocardiogram monitoring and not precluding the ability to work.
