Durante o acompanhamento de seis semanas de ratos machos e fêmeas portadores de Infarto do Miocárdio não foram encontradas diferenças consistentes que caracterizem peculiaridades da evolução de dados estruturais e funcionais definidos pelo estudo Doppler ecocardiográfico dependentes de gênero. De modo geral, tanto machos quanto fêmeas tiveram repercussões anátomo-funcionais cujas intensidades sofreram influência do tamanho do IM e do tempo de evolução que se seguiu à oclusão coronária. É necessário considerar que o tempo de seguimento dos animais pode ter sido insuficiente para que diferenças de gênero pudessem se manifestar. Secundariamente, nossos resultados possibilitaram caracterizar que o hábito arraigado de normalizar dados dimensionais cardíacos pelo peso corpóreo nem sempre favorece a análise das modificações impostas patologicamente. Não foi raro, em nossos casos, que a correção de variáveis dimensionais pelo peso corpóreo desfigurou marcadamente informações obtidas pelos dados considerados em valores absolutos.
