OBJECTIVE: To analyze clinical and laboratorial findings of authoctononus acute Chagas disease from Brazilian Amazon, evaluated under hospital regimen, emphasizing feverish syndrome observations and potential signs of future cardiac commitment. METHOD: Transversal study of acute Chagas disease in patients from University Hospital João de Barros Barreto, within jan 1990 to at 2003. RESULTS: In a total of 20 studied cases we found predominant symptoms: fever (95%), dyspnea (75%), asthenia (65%), edema of lower members (65%) and headache (60%). Main abnormalities found in electrocardiograms were: sinusal tachycardia, diffuse ventricular repolarization abnormalities and low voltage of QRS. We demonstrated 35% with pericardial effusion show in echocardiograms. CONCLUSIONS: Raised frequency of feverish syndrome in acute Chagas disease shows the importance of the correct distinguishing diagnosis with others febrile endemic diseases occurred in Amazon. The electrocardiographics and echocardiographics abnormalities found could suggest clinical form of transition for chronicity, besides expressing gravity.
