Uma das estratégias mais utilizadas para o estudo das alterações fisiopatológicas decorrentes da oclusão coronariana é o uso do modelo do infarto experimental no rato. Entre outros fatores, esse fato é decorrência da similaridade com as alterações fisiopatológicas que ocorrem após o infarto, em humanos. Devemos considerar, entretanto, que esse modelo possui características que podem dificultar tanto o uso como a interpretação de eventuais resultados. Assim, essa revisão tem como objetivo discutir as principais características do modelo do infarto experimental no rato, abordando a técnica da oclusão coron...
