The cardiac effects of experimentally induced myocarditis, when the parasite is obtained from mouse blood, are well known. However, the consequences of the infection when the parasites are obtained from bug faeces are less well defined. In the presen

The pathogenesis of Chagas' disease has been linked to abnormalities of the autonomic nervous system, since the very early descriptions of the disease [1,2]. Thus, Koberle postulated in the 1950s his very well known neurogenic hypothesis, on the path

We administered arecoline to rats, with experimentally induced chagasic myocarditis, in order to study the sinus node sensitivity to a muscarinic agonist. Sixteen month old rats were inoculated with 200,000 T. cruzi parasites ("Y" strain). Between da

Cardiac parasympathetic innervation in Chagas' heart disease

Publikováno v: Medical Hypotheses. 35:80-84

Trypanosoma cruzi is thought to selectively destroy the postganglionic cardiac vagal neurons of chagasic cardiac patients. This theory is based on morphologic and functional evidences obtained from chagasic individuals who were in very advanced stage

Electrocardiographic abnormalities and left ventricular systolic function in Chagas' heart disease

Publikováno v: International journal of cardiology. 27(1)

In chagasic patients, the electrocardiogram becomes abnormal very late in the course of the disease. Most clinical studies concerning cardiac autonomic function of chagasic patients have been carried out in this very late stage of the disease. The pu
