Developments in Preventing Catastrophic Racehorse Injuries

Catastrophic injuries in Thoroughbred racehorses is a top-of-mind concern for the racing industry and for its fans. That sentiment is shared by researchers at the University of Kentucky, who are working to learn more about the changes happening at a cellular level that might indicate an injury is present before it becomes career or life ending.

Might it be possible to identify an early marker or signal for horses at risk of catastrophic injury, allowing for intervention before those injuries happen? And, if yes, might this type of detection system be one that could be implemented cost effectively on a large scale?

According to Allen Page, DVM, PhD, staff scientist and veterinarian at UK’s Gluck Equine Research Center, the short answer to both questions is that it looks promising.

For the past three years, Page, along with UK colleagues, has been analyzing blood samples from more than 1,000 Thoroughbred racehorses. The samples, collected by participating racing jurisdictions from across the country, have come from both catastrophically injured and non-injured horses in a quest to better understand changes that might be happening at the cellular level during racing and if there are any molecular red flags which consistently differentiate horses that suffer a catastrophic injury
