This year's Grade I Kentucky Derby winner and Breeders' Cup Classic runner-up Medina Spirit collapsed and died this morning on the track at Santa Anita of an apparent heart attack after recording a workout.
The colt’s owner Amr Zedan confirmed to Thoroughbred Daily News that the colt had suffered a fatal collapse while working at Santa Anita.
The Derby win is still unconfirmed after the colt failed subsequent drug tests that found the presence of the banned steroid betamethasone in the horse’s system.
Medina Spirit's trainer Bob Baffert had said the betamethasone might have from an ointment used on the colt and the case is still ongoing.
Last week, Baffert's lawyer Craig Robertson released a statement that testing of the split urine sample of Medina Spirit has been completed and the results had confirmed that the betamethasone present in Medina Spirit’s system following the Derby came from the topical ointment Otomax and not an injection.
The Paulick report reported that Dr. Blea, former American Association of Equine Practitioners president said after the colt's death:
“I will have them draw blood and pull hair and will try and get urine for testing. He'll go out to UC Davis in San Bernardino, for a full and
comprehensive necropsy including toxicology, forensics and tissue sampling. We will take a close look at the heart to try and identify the cause of death.”
