Feline comorbidities: cardiovascular and kidney diseases

Area of Science:

• Veterinary Medicine
• Cardiology
• Nephrology

Background:

• Concurrent cardiovascular and kidney diseases are common in aging cats.
• Interactions between heart and kidney disease can lead to progressive organ dysfunction.
• Clinicians must consider the impact of treating one condition on the other organ system.

Purpose of the Study:

• To address the challenges in managing fluid balance in cats with coexisting heart and kidney disease.
• To highlight therapeutic conflicts between treating heart failure and kidney disease.
• To provide guidance for veterinary practitioners on managing these complex cases.

Main Methods:

• Recommendations derived from peer-reviewed literature.
• Inclusion of expert consensus guidelines where available.
• Synthesis of current knowledge for practical application.

Main Results:

• Therapies for kidney disease (e.g., fluid therapy) can conflict with heart failure management (e.g., diuretics).
• Improper fluid management can cause injury or stress to the contralateral organ.
• Balancing fluid therapy is critical for maintaining mean arterial pressure and renal blood flow while reducing capillary hydrostatic pressure.

Conclusions:

• Optimal management of cats with concurrent heart and kidney disease necessitates a delicate balance of fluid therapy.
• Understanding the interplay between cardiac and renal systems is crucial for successful case management and prognosis.
• Veterinary practitioners require awareness of potential iatrogenic complications arising from therapeutic interventions.
