Evaluación de pacientes caninos de la clínica veterinaria Dr. Pet con enfermedad mitral en estadio ACVIM B1 con dilatación del ventrículo izquierdo en fin de diástole.

Abstract

Mitral valve disease is one of the most prevalent heart diseases in canines, which is the reason why the ACVIM establishes a classification system according to the stages of this disease, with the aim of facilitating the clinical approach with patients. This system mentions that treatment should be implemented once cardiac remodeling is observed, that happens in stage B2. In the following investigation, the frequency of left ventricular dilatation at the end of diastole was evaluated in dogs with mitral disease that were in stages ACVIM B1 that went to cardiology consult at Dr. Pet, through the measurement of AI/Ao ratio and LVDd in echocardiography, also evaluating the influence of the variables race, sex, age and weight in the presentation of this condition. This study had a non-experimental quantitative approach with a descriptive and correlational scope, where the population corresponded to the canines that attended the clinic between the months of October to December of the year 2022. The results reflected a total of 82 dogs diagnosed with this valve disease, of which 64.63 % were in the ACVIM B1 stage, and from this total, 69.81 % presented volume overload in the left ventricle, however, in the Chi square test it was observed that none of the aforementioned variables have a direct effect on this condition. In conclusion, patients in earlier stages of this disease could establish a therapeutic plan to control its degenerative development.
