Resumo: Mitral flow propagation velocity (Vp) is an index used to evaluate the left ventricular diastolic function. Its influence on human and small animal cardiopathies has been studied; however there are few reports evaluating this variable in domestic felines. In addition, there is a lack of studies in non-sedated healthy cats. Therefore, the purpose of this study was to establish values for Vp and its correlation with other echocardiographic indexes in non-sedated healthy cats in order to provide new perspectives related to diastolic function in this species. Twenty-six clinically healthy cats were submitted to echocardiography to assess the animals' cardiac conditions. Variables such as age, heart rate (HR), body surface area (BSA), initial (E mitral) and late (A mitral) ventricular filling waves, isovolumic relaxation time (IVRT) and E/IVRT relation were correlated to Vp. No proven relation between any of these variables and Vp was observed in this present study, except for HR and BSA. In the variability analysis, higher values were verified for inter-observer analysis. This study concludes that Vp proved to be an useful index for estimating left ventricular relaxation in non-sedated healthy domestic cats and provides reference ranges for this variable.

Sua importância nas cardiopatias em humanos e pequenos animais vem sendo estudada; porém, há poucos trabalhos avaliando essa variável em gatos domésticos. Nessa espécie, estudos utilizando animais saudáveis e não sedados não foram encontrados na literatura. Dessa forma, objetivou-se estabelecer os valores da Vp e sua correlação com outros índices ecocardiográficos em gatos domésticos saudáveis e não sedados, de forma a fornecer novas perspectivas relacionadas à função diastólica nessa espécie. Foram utilizados 26 gatos domésticos clinicamente saudáveis, submetidos à ecocardiografia para se avaliar a condição cardíaca dos animais. As variáveis idade, frequência cardíaca (FC), área de superfície corporal (SAC), idade, onda de enchimento ventricular inicial (E mitral) e tardio (A mitral), tempo de relaxamento isovolumétrico (TRIV) e a relação E/TRIV foram correlacionadas com a Vp. No presente estudo não foi observada correlação da Vp com nenhuma das variáveis estudas, exceto com a FC e o SAC. Quanto à análise de variabilidade, foi observado um maior valor para a análise inter-observador. O estudo permite concluir que a Vp demonstrou ser um índice útil para se estimar o relaxamento ventricular esquerdo em gatos domésticos saudáveis e não sedados, além de fornecer valores de referência para essa variável.Universidade Federal de Minas Gerais, Escola de Veterinária2020-02-06T11:51:31Z2020-02-06T11:51:31Z2014info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfSILVA, A.
