Resumo
A endocardiose da válvula mitral é uma cardiopatia de alta incidência na clínica médica de pequenos animais, com maior acometimento de cães idosos e de raças de pequeno porte. Realizou-se então um estudo para avaliar clinicamente a utilização do maleato de enalapril, furosemida, espironolactona e suas associações, em cães com endocardiose de válvula mitral classes funcionais Ib e II, antes e após a terapêutica implantada. Para isso, utilizaram-se 36 animais portadores desta afecção, distribuídos em quatro grupos, conforme as classes funcionais de ICC, com terapêutica específica implantada durante 56 dias em cada grupo estudado. Animais portadores da classe funcional Ib foram distribuídos em dois grupos, com o primeiro recebendo furosemida (n=8) e o outro maleato de enalapril (n=8). Igualmente, distribuíram-se os animais da classe funcional II, com um grupo recebendo maleato de enalapril e furosemida (n=10) e o segundo, enalapril associado à espironolactona e furosemida (n=10). Todos os grupos foram avaliados em quatro momentos (T0, T14, T28 e T56 dias) quanto aos parâmetros e sinais clínicos, exames hematológicos e bioquímico-séricos, que incluíram enzima conversora da angiotensina (ECA) e aldosterona; avaliações radiográficas, eletrocardiográficas, ecodopplercardiográficas e da pressão arterial. Os resultados demonstraram uma redução dos sinais clínicos nos animais classe II, com a estabilização dos parâmetros em ambos os grupos. As avaliações hematológica e bioquímico sérica não revelaram alterações significativas nas classes estudadas, mas uma redução significativa dos valores de ECA e aldosterona foram observadas nos grupos que receberam enalapril como terapêutica. Ao exame radiográfico observou-se redução dos valores de VHS e, ao eletrocardiograma as variáveis onda Pms e Complexo QRSms apresentaram diminuições significativas...
The endocardiosis of mitral valve is a high incidence of heart disease in the medical clinic for small animals, with the involvement of older dogs and small breeds. This is a clinical study to evaluate the use of the enalapril maleate, furosemide, spironolactone and their associations in dogs with mitral valve endocardiosis of class Ib and II, before and after therapy implanted. It was used 36 animals with this endocardiosis, divided into four groups according to class of congestive heart failure, implanted with a specific therapy for 56 days in each group. The animals classified in class Ib was divided into two groups, with the first receiving furosemide (n = 8) and the other of maleate of enalapril (n = 8). It is also divided the animals of Class II, with a group of receiving maleate of enalapril and furosemide (n = 10) and second, enalapril combined with spironolactone and furosemide (n = 10). Every groups were available in four moments (T0, T14, T28, e T56 days) as to clinical parameters, symptoms, serum biochemical and hematological tests, which included the angiotensin converting enzyme (ACE) and aldosterone; radiographic evaluations ECG, Dopplerechocardiography and blood pressure. The results showed a reduction of clinical signs in animals Class II, with stabilization of physiological parameters in both groups. The serum biochemical and hematological evaluation showed no significant changes in the classes studied, but a significant reduction of the values of ACE and Aldosterone were seen in the groups receiving enalapril as therapy. By radiographic examination, we observed a reduction of the values of VHS, and the variables Pms wave and QRSms Complex in electrocardiogram showed significant variations in groups of Class II. The absence of variations in blood pressure was observed in both groups. But the Dopplerechocardiogram showed a ventricular remodeling with a significant decrease...
