Resumen

GOLDBAUM, Moisés et al. American trypanosomiasis and electrocardiographic alterations among industrial workers in São Paulo, Brazil. Rev. Inst. Med. trop. S. Paulo [online]. 2004, vol.46, n.6, pp.299-302. ISSN 1678-9946.  https://doi.org/10.1590/S0036-46652004000600001.

In this article, we evaluate electrocardiographic (ECG) alterations among urban workers from a mechanical-metallurgical industry in São Paulo, Brazil. In a cross-sectional survey carried out in 1980, we found 2.2% positive serological testing for Trypanosoma cruzi infection among 27,081 workers. A comparison between seropositive workers and a random sample of seronegative workers frequency-matched by age and occupation revealed that seropositive workers had a much lower educational level, and that a higher proportion of seropositive workers had ECG abnormalities (42.7%) when compared to those negative for T. cruzi infection (19.8%). The high frequency of ECG abnormalities suggests the need to provide medical assistance to these workers, without any kind of discrimination and to bring in a form of management that would decrease this dangerous risk to the workers and people around them.
