| Research Abstract |
The purpose of this study was to evaluate the effects of various medication used for heart failure on autonomic tone and renin-angiotensin aldosterone system (RAAS) in dogs with chronic valvular heart disease. Five dogs with experimentally induced mitral regurgitation were used. Furosemide, furosemide and pimobendan, combination of furosemide, pimobendan and enaralril, azosemide and placebo were administered in the cross-over design. Variables of heart rate variability were not significantly different among groups. Urine aldosterone creatinine ratio was increased due to furosemide, however, concurrent administration of enalapril did not seem to suppress RAAS activation. Azosemide appeared minimally influence to RAAS.
