Resumen

El objetivo del presente estudio fue reconocer la relación de las variaciones en las concentraciones de lactato plasmático y de presión arterial en pacientes caninos con enfermedad cardíaca valvular crónica, sometidos a la prueba de marcha de 6 minutos en condiciones de gran altura (2650 msnm). Siete animales fueron seleccionados y se diagnosticaron a través del Servicio de Cardiología de la Clínica Veterinaria de la Universidad de la Salle, siendo clasificados como pacientes en estadio B2 según la clasificación del Colegio Americano de Medicina Interna Veterinaria (ACVIMpor su sigla en inglés). Se compararon las mediciones de la presión arterial y lactato plasmático antes y después de la prueba de 6 minutos WT. Se encontró una distancia recorrida promedio de 356.14 +/- 92.13 metros, la cual es considerablemente menor a distancias reportadas en pacientes sanos bajo las mismas condiciones medioambientales. Asimismo, se observó una reducción en la presión arterial sistólica posterior a la prueba de marcha (112.71 +/- 31.83 mmHg) comparada con los valores iniciales (132.14 +/- 26.67 mmHg) p<0.05. Esto sugiere la presentación de un fenómeno de hipotensión post ejercicio de la cual hasta ahora no se han encontrado muchos reportes en la especie canina.
