ABSTRACT
Abstract Cardiorenal syndrome type 1 (CRS 1) occurs when acute heart failure leads to acute kidney injury. There are several etiologies of CRS 1, including Chagas disease. Here, we present the first case report of CRS 1 in a patient with acute Chagas disease. Electrocardiography, transthoracic echocardiography, and cardiac magnetic resonance imaging showed signs of acute myocarditis. Laboratory examination revealed severe loss of kidney function, with a creatinine clearance of 30 mL/min, which fully normalized after treatment. Due to emergence of Chagas disease in the Brazilian Amazon, it is important to report unique clinical features in order to improve patients' outcomes.

Fundamento: Recentemente tem ocorrido aumento do número de casos agudos de doença de Chagas, principalmente causados por transmissão oral. A maioria dos pacientes mostra boa evolução, apresentando sintomatologia compatívelcom processo infeccioso sistêmico, porém sem alterações cardíacas significativas ao exame físico, eletrocardiograma eecocardiograma transtorácico.Objetivo: Avaliar alterações ecocardiográficas com análise do Doppler tecidual em pacientes com doença de Chagas aguda. Métodos: Foram avaliados pacientes com diagnóstico de doença de Chagas aguda confirmada por exame parasitológico direto. Esses pacientes foram submetidos a exame físico, eletrocardiograma e ecocardiograma transtorácico, sendocomparados com um grupo controle.Resultados: Foram avaliados 12 casos com doença de Chagas aguda e 15 indivíduos no grupo controle. As variáveis que apresentaram diferenças significativas foram: ondas S lateral de VE (DCA = 0,09 ± 0,02 m/seg; GC = 0,11 ± 0,02 m/seg; p = 0,024); E lateral (DCA = 0,13 ± 0,03 m/seg; GC = 0,18 ± 0,03 m/seg; p = 0,001); E septal do VE (DCA = 0,10± 0,03 m/seg; GC = 0,14 ± 0,03 m/seg; p = 0,008), A lateral do VE (DCA = 0,08 ± 0,03 m/seg; GC = 0,12 ± 0,01 m/seg;p = 0,003), onda S do VD (DCA = 0,12 ± 0,02 m/seg; GC = 0,17 ± 0,02 m/seg; p < 0,001) e TAPSE (DCA = 1,95 ±0,41 cm; GC = 2,37 ± 0,25 cm; p = 0,006). Conclusões: Em pacientes com doença de Chagas aguda, mesmo quando apresentam evolução benigna, podem ocorrer alterações subclínicas detectadas principalmente ao Doppler tecidual. Essas alterações podem ser importantes na avaliação do tratamento da fase aguda e na sua evolução a longo prazo.
Background: Recently there has been an increased number of cases of acute Chagas disease primarily caused by oral transmission. Most patients have a good outcome, presenting symptoms consistent with systemic infectious process, but no significant cardiac abnormalities on physical examination, electrocardiogram and echocardiogram.Objective: To evaluate echocardiographic changes with tissue Doppler analysis in patients with acute Chagas disease.Methods: We evaluated patients with acute Chagas disease confirmed by cytological examination. These patients underwent a physical examination, eletrocardiogram and transthoracic echocardiography, and compared with a control group. Results: We evaluated 12 patients with acute Chagas disease and 15 subjects in the control group. Variables that showed significant diferences were waves S side of LV (DCA = 0.09 ± 0.02m/sec; CG = 0.11 ± 0.02 m/sec; p = 0.024); and side (DCA = 0.13 ± 0.03 m/sec; CG = 0.18 ±0.03 m/sec; p = 0.001); Septal E LV (DCA = 0.10 ± 0.03 m/sec; CG = 0.14 ± 0.03 m/sec; p = 0.008), A lateral LV (DCA = 0.08 ± 0.03 m/sec;CG = 0 12 ± 0.01 m/sec; p = 0,003), S wave RV (DCA = 0.12 ± 0.02 m/sec; CG = 0.17 ± 0.02 m/sec; p < 0.001) and TAPSE (DCA = 1,95cm ± 0.41; CG = 2.37 ± 0.25 cm; p = 0.006). Conclusions: In patients with acute Chagas disease, even when present benign, there may be subclinical alterations detected primarilyby tissue Doppler. These changes may be important in the treatment of acute and its long-term evolution.

É relatado episódio de acidente vascular encefálico isquêmico em paciente chagásico crônico autóctone da Amazônia. Este é o primeiro caso documentado da forma predominantemente tromboembólica da cardiopatia chagásica crônica na região.
An episode of stroke in a chronic autochthonous chagasic patient from the Brazilian Amazon is reported. This is the first documented case of a predominantly thromboembolic form of chronic Chagasic cardiopathy in the region.

Descreve-se o acometimento cardíaco em cinco pacientes autóctones da Amazônia com diagnóstico de Doença de Chagas Aguda (DCA). Quatro desses pacientes apresentaram provável transmissão oral. Todos apresentaram algum grau de acometimento cardíaco, não havendo nenhum óbito.
The cardiac involvement of five patients from the Amazon region with Acute Chagas' Disease (ACD) is described. Four of these patients presented probable oral transmission. All of them presented some degree of cardiac involvement, but there were no deaths.
