Description
Summary:In order to learn the prevalence of Chagas' infection among students from Santa Cruz de la Sierra's universities, a random sample of 372 new students was drawn. All participants have had electrocardiograms (EKG) and serologic analysis (IHAT). 64/372 (17.2%) had serologic evidence of Chagas' infection, and from those, 10/64 (15.6%) had some EKG alterations. Among students presenting negative serologic test, 31/308 (10.1%) had EKG alterations. There was no statistical association between Chagas' infection and EKG alterations (X2=1.67, p=0.2). There was a positive association between Chagas' infection and intraventricular conduction defects and this association was higher among the students of 19 years of age or less (O.R. 10.4, p<0.05). Desde una población de 4600 nuevos estudiantes de la Universidad Estatal de la ciudad de Santa Cruz de la Sierra, se tomó una muestra aleatoria de 372 estudiantes a los que se les realizó un test de hemaglutinación indirecta (HAI) para enfermedad de Chagas y un electrocardiograma (ECG) convencional. El 17.2% (64/373) tenían el test HAI positivo y de estos el 16.5% (10/64) tenían algún trastorno electrocardiográfico. En el grupo con HAI negativa el 10% (31/308) presentó alguna anormalidad electrocardiográfica. No se observó asociación entre serología positiva para la enfermedad de Chagas y alteración del ECG en general (X2=1.67 p=0.2). Se observó una asociación positiva entre serología para Chagas y trastornos de conducción intraventricular (TCIV) y ésta parece intensificarse entre los menores de 19 años con un odds ratio de 10.4 (p<0.05).
