Cardiomiopatia dilatada por virus H1N1

Mulher de 58 anos, sem antecedentes medicos relevantes, apresenta infeccao respiratoria pelo virus H1N1, requerendo internacao na Unidade de Cuidados Intensivos. Apos a alta, refere progressiva astenia e dispneia, sendo internada nove meses depois por derrame pleural e infeccao respiratoria. Avaliacao especifica pela Cardiologia revela cardiomiopatia dilatada com ma funcao sistolica do ventriculo esquerdo, compativel com miocardite. A ressonância magnetica se apresenta compativel com miocardite. Dados os antecedentes e havendo sido descartada doenca autoimune e toxica, associou-se a doenca ao virus H1N1. O prognostico e muito positivo, com recuperacao quase total da funcao do ventriculo esquerdo. A 58-year-old woman with no relevant prior medical conditions presented a respiratory infection caused by theH1N1 virus, requiring admittance to an Intensive Care Unit. After discharge, the patient complained of progressiveasthenia and dyspnea, being hospitalized nine months later with a diagnosis of pleural effusion and respiratory infection. Further evaluation by the Cardiology Unit revealed dilated cardiomyopathy with poor systolicfunction of the left ventricle, compatible with myocarditis. A cardiac magnetic ressonance examination was compatible with myocarditis. Given her previousadmittance and having ruled out toxic aspects and autoimmune disease, the disease was associated with the H1N1 virus. The prognosis is very positive, with almost complete recovery of the left ventricular function.
