Abstract in Portuguese
Objetivos: Avaliar a evolução e as complicações dos doentes que sobreviveram a ferimentos cardíacos, atendidos no Pronto-Socorro Municipal 28 de Agosto e Hospital Pronto-Socorro Dr. João Lúcio Pereira Machado, em Manaus, no período de janeiro de 1998 a junho de 2006. Métodos: Foi realizada uma busca de prontuários dos doentes atendidos nos dois prontossocorros, nos quais durante a toracotomia exploradora evidenciou-se o ferimento cardíaco. Os sobreviventes que retornaram ao ambulatório foram avaliados prospectivamente por meio de eletrocardiograma e ecocardiograma, para averiguar a morfologia e a funcionalidade do coração. Foi preenchido um protocolo com registro dos dados dos doentes, tais como: idade, sexo, mecanismo de trauma, complicações intra e pós-operatórias, dentre outras variáveis. Resultados: A população de referência totalizou 100 doentes, dos quais 95% eram homens, 69% entre 20 e 30 anos; 81% das lesões foram por arma branca, sendo que em 78% delas, a entrada se encontrava no precórdio; 41% das lesões acometeram o ventrículo direito (VD) e 38% acometeram o ventrículo esquerdo (VE); em 48% dos casos foi realizada toracotomia ântero-lateral esquerda. A sobrevivência foi de 72%. A população de estudo foi composta por 25 doentes que retornaram ao ambulatório e foram avaliados prospectivamente por meio de eletrocardiograma e ecocardiograma. Das 33 alterações no ecocardiograma (ECO), sete doentes (28%) tinham insuficiência mitral, enquanto nove (36%) não tinham alterações. Das 45 alterações no eletrocardiograma (ECG), oito doentes (32%) tinham taquicardia sinusal, enquanto seis (24%) não tinham alterações. Não houve efeito do tempo no resultado do ECO (p=0,5323) ou do ECG (p=0,6596). Das alterações detectadas no ECO, três (21,4%) foram devidas a lesões grau IV (em VD) e 11 (78,7%) devidas a lesões grau V (em VE) (p=0,048). Das 12 alterações detectadas no ECG, três (25%) relacionaram-se a lesões grau IV e nove (75%) relacionaram-se a lesões grau V (p=0,226). Conclusões: Aproximadamente um terço dos sobreviventes a lesões cardíacas não apresentaram alterações ao eletrocardiograma e ecocardiograma. Ventrículo esquerdo e grau de lesão V da OIS-AAST estiveram relacionados a um maior número de alterações ao eletrocardiograma e ecocardiograma. Taquicardia sinusal e insuficiência mitral foram alterações encontradas em um de cada três doentes que sobreviveram a um ferimento cardíaco.

Abstract in English
Objectives: To evaluate the evolution and the complications of the patients that survived cardiac wounds, attended at the Pronto-Socorro Municipal 28 de Agosto and Hospital Pronto-Socorro Dr. João Lúcio Pereira Machado, in Manaus, during the period of January 1998 until June 2006. Methods: A medical records evaluation was made among the patients attended at the two emergency hospitals in which a cardiac wound was found during a exploring thoracotomy. The survivors that returned to the ambulatory were evaluated prospectively through electrocardiogram and echocardiogram, so it was possible to analyze the morphology and the function of the heart. A protocol was filled out with a registry of patients data, such as: age, sex, trauma mechanism, intra-operative and post-operative complications, and other variables. Results: The total reference population in this study was 100 patients, in which 95% were male, the majority (69%) had ages until 30; 81% of the lesions were caused by stab wounds; 78% of the orifice of entry were located at the precordium; 41% of the lesions wounded the right ventricle and 38% wounded the left ventricle; In 48% of the cases a left antero-lateral thoracotomy was executed. The survival rate was 72%. The studied population was of 25 patients that returned to the ambulatory and were prospectively evaluated with electrocardiogram and echocardiogram. Among the 33 echocardiogram alterations (ECO), seven patients (28%) had mitral insufficiency, while nine (36%) didn't have any alterations. Among the 45 electrocardiogram alterations (ECG), eight patients (32%) had sinusal tachicardia, while six (24%) had no alterations. Time made no difference in the results of the ECO (p=0,5323) or of the ECG (p=0,6596). Of the 14 detected ECO complications, three (21,4%) were due to IV degree lesions in the right ventricle and eleven (78,7%) were due to V degree lesions (in the left ventricle) (p=0,048). From the 12 left ventricle lesions that complicated (ECG), 9 were V degree. From the 12 alterations detected at the ECG, three (25%) were due to IV degree lesions and nine (75%) were due to V degree lesions (p=0,226). Conclusions: Approximately one third of the cardiac wound survivors did not have alterations in the electrocardiogram and echocardiogram. Left ventricle and V degree lesions from the OIS-AAST were related to a larger number of alterations in the electrocardiogram and echocardiogram. Sinusal Tachicardia and mitral insuficiency were alterations found in one third of the patients that survived a cardiac wound.
