AGUILAR, Raúl et al. Infección por trypanosoma cruzi y bloqueo cardíaco del nodo auriculoventricular en el salvador. Medicina (B. Aires) [online]. 2021, vol.81, n.2, pp.154-158. ISSN 0025-7680.

Chagas disease is endemic in Latin America and remains a regional problem despite improvements in en vironmental health conditions that have helped to control its transmission. To know more about its prevalence in heart disease patients, we carried out a survey in our national (El Salvador) reference hospital. We reviewed the Chagas Lab´s records 2013-2015 to find out how many of the patients admitted to the Hospital´s Heart Unit were serologically positives for Trypanosoma cruzi infection and which the associated diagnoses were. A total of 1472 patients were tested along the 36-month study period. Out of 557 (37.8%) patients with positive serology for Chagas infection, 97 (17.4%) were eventually admitted to the Heart Unit. Among these 97 Chagas infected patients with heart disease, 40 (41.2%) met the criteria for permanent pacemaker placement, while only 13 of 191 (6.8%) patients with non-chagasic heart disease met these criteria. The frequency of heart atrioventricular block associated with Trypanosoma cruzi infection was higher than frequencies reported in South American studies.
