Abstract
Introduction:
Myxomatous mitral valve disease (MMVD) in dogs inevitably causes renal
dysfunction. These interactions are known as the cardiorenal syndrome (CRS).
The main aims of the study were to evaluate whether renal resistive index
(RRI) may be useful as a non-invasive marker in subclinical stage of kidney
injury in dogs with MMVD and to compare RRI with SDMA and Cyst C.
Methods:
Forty-four dogs were divided into two groups: control—15 healthy dogs
and the heart group—29 dogs with MMVD (ACVIM class Cc). Study
protocol included: anamnesis, clinical examination, electrocardiography,
echocardiography, chest radiography, abdominal ultrasonography with
measurements of the renal resistive index (RRI), urine, and blood
analysis.
Results:
The RRI in the heart group was significantly higher
0.725 ± 0.035 versus control group
0.665 ± 0.028
(p < 0.00085). The RRI cut-off
point in dogs with stable chronic heart failure (CHF) under 8 years
is 0.775, in older 0.64. RRI was similar in MMVD dogs treated with
ACE-I + furosemide and dogs treated
ACE-I + torasemide + pimobendan + spironolactone.
There was no correlation between RRI and SDMA or Cyst C.
Conclusion:
RRI is more sensitive than creatinine, SDMA and Cyst C to reveal kidney
injury in MMVD dogs class Cc younger than 8 years.
