Horseracing Integrity and Safety Authority is working with researchers nationwide to study the condition and develop guidance for trainers and veterinarians on the best approaches to treating horses experiencing atrial fibrillation.

The Horseracing Integrity and Safety Act of 2020 established the Horseracing Integrity and Safety Authority (HISA), for the purpose of developing and implementing an Anti-Doping and Medication Control (ADMC) Program and a Racetrack Safety Program comprised of national, uniform rules and regulations to make racing safer for both human and equine athletes and strengthen the integrity of the sport. HISA will begin implementation and enforcement of the Racetrack Safety Program on July 1, 2022. The rules and national accreditation standards were drafted by a committee of independent and industry experts and have been through a multistage consultation, stakeholder engagement and public comment process culminating in its approval by the Federal Trade Commission (FTC). HISA continues to make significant progress in bringing together industry stakeholders and independent members in various fields to usher in a new and safer era for thoroughbred racing and its athletes.
