Exertional rhabdomyolysis in a 4-year-old standardbred filly.

The research focuses on a case of exertional rhabdomyolysis diagnosed in a young Standardbred filly that exhibited signs of stiffness and discomfort after racing, and was successfully managed with limited exercise and a specific dietary plan.

Overview of the case

• The research revolves around the case of a 4-year-old Standardbred filly that presented symptoms of stiffness and unease following a race.
• The horse’s symptoms included marked elevations in the levels of certain enzymes – creatine kinase, aspartate aminotransferase, and lactic dehydrogenase, strongly suggesting muscle damage.

Diagnosis

• Based on the presented symptoms and the elevated enzyme levels, the filly was diagnosed with exertional rhabdomyolysis, a condition involving muscle breakdown usually following strenuous exercise, which in horses, can occur due to a variety of factors including genetic predisposition, improper training or nutrition among others.

Treatment and Management

• The filly’s treatment plan included restricting her exercise and altering her diet to include low carbohydrate and high fat content.
• These interventions aimed to allow the filly’s body to recover from the muscle breakdown and avoid further instances of the condition by reducing muscular exertion and providing a more suitable nutritional source of energy.

Post-treatment Results

• Eight days after initiating this treatment and management plan, the filly participated in a race without experiencing any negative effects, thus demonstrating the effectiveness of the provided interventions.
