RESUMO

To evaluate clinical and evolutive features in patients with initial asymptomatic cardiac Chagas disease, a prospective study was carried out with 108 patients, age 18 and 50, at the Londrina State University Chagas disease outpatient clinic, from April to November 2002. Patients were submitted to: 1) clinical evaluation, 2) electrocardiography (EKG), 3) chest radiography and cardiothoracic index (CTI), 4)24-hour dynamic electrocardiography, 5) bi-dimensional echocardiography with tissued Doppler imaging and 6) type-B natriuretic peptide (BNP) plasmatic dosage. Patients were divided into 3 groups: GI - normal EKG and CTI (50 patients), GIIA - EKG with typical Chagas disease alterations (31 patients) and GIIB - EKG with alterations not characteristic of Chagas´ disease (25 patients)
