Cardiomiopatia dilatada canina, a propósito de 13 casos clínicos

Abstract

ABSTRACT - Dilated Cardiomyopathy, in view of 13 clinical cases Dilated cardiomyopathy (DCM) is a very relevant and prevalent disease in dogs, being one of the main affections of the cardiovascular system. It occurs mainly in pure large breed dogs and is characterized by a slow progression that is maintained, without being noticed, by the cardiovascular compensatory system. The disease leads to a progressive reduction of miocardic contractility which determines, initially, a systolic dysfunction. Compensatory mechanisms, that are efficient in the beginning, end up failing through the DCM progression, which provokes the development of symptoms. The majority of the DCM cases are diagnosed by this time. Diagnose is essentially based on echocardiographic, electrocardiographic and radiologic observations. Prognosis is poor and always leads to death. Therapy administration can initially stabilize the patient and offers an opportunity to extend the survival time. This work, at beginning, is related to the practice period developed in Instituto Veterinário do Parque (IVP), where the referred cases have been diagnosed. A revision of the actual knowledge of the disease have been made, which assists the reading and understanding of the study developed. The study is centered on the clinical evaluation of DCM affected animals presented to IVP since September 08 until July 09 (n=13). The analysis was made recurring to echocardiography, electrocardiogram, and considering general changes and drugs administered. Besides, tree clinical cases have been followed, in which is possible to understand disease progression and therapeutic effects. It has been determined the DCM prevalence in IVP (1.06%) and the age and breed of the patients. Considering patient’s breeds, it should be raised two Serra da Estrela dogs, which belong to an autochthonous breed with national relevance.

A cardiomiopatia dilatada (CMD) é uma doença muito importante no seio das doenças cardiovasculares caninas, sendo uma das mais frequentes. Caracteriza-se principalmente por uma redução gradual e progressiva da contractilidade miocárdica que determina uma disfunção inicialmente sistólica, marcada por uma evolução lenta que se encontra equilibrada pelos sistemas compensatórios do organismo. Contudo, a falência destes mecanismos leva ao súbito desenvolvimento de sintomatologia sendo, a maioria dos casos de CMD, apenas diagnosticados por esta altura. O diagnóstico baseia-se essencialmente no uso da ecocardiografia, do electrocardiograma e da radiologia, sendo o prognóstico reservado com um percurso invariavelmente fatal. Porém, a terapêutica permite manter a condição de vida do paciente e prolongar a sobrevivência. Este trabalho visa inicialmente o estágio realizado no Instituto Veterinário do Parque (IVP) seguindo-se a abordagem ao tema, que começa por uma revisão dos conhecimentos existentes sobre a CMD, tentando desenvolver-se uma pesquisa o mais completa possível. O estudo centra-se na avaliação clínica dos animais afectados presentes à consulta entre Setembro de 2008 e Julho de 2009 (n=13), com o recurso à ecocardiografia e ao electrocardiograma, fazendo-se uma análise geral das alterações observadas, da medicação instituída e um acompanhamento de três casos clínicos nos quais é possível perceber a progressão da doença e os efeitos terapêuticos. É apresentada, ainda, a prevalência desta doença no IVP (1,06%), a idade e raça dos pacientes, onde se deve realçar dois animais Serra da Estrela, cuja importância se destaca por se tratar de uma raça autóctone de relevância nacional.
