2YO Lasix Study Procedures

A survey study of 2-year-olds that race in Maryland this year to determine the extent of exercise-induced pulmonary hemorrhage began Aug. 7 at Laurel Park and will continue Friday, Aug. 21, when a pair of 2-year-old races are carded.

Private veterinarians who practice at Laurel are conducting the video endoscopies and will complete information forms for each horse that include the horse’s name, its EIPH score, any related comments, and whether the horse trains on Lasix. Horses are being scoped post-race when they return to the barns in which they are stabled.

Horsemen should notify the Maryland Jockey Club Racing Office if they choose to have a horse scoped. Owners and trainers do not have to pay for the video endoscopies. Grooms must wait with a horse until it is scoped.

The survey study is part of a broader agreement between the Maryland Thoroughbred Horsemen’s Association and The Stronach Group for the Lasix-free pilot program that runs through 2023 for 2-year-old races. The Maryland Racing Commission is maintaining all records from the survey study, and only a horse’s owner and trainer will be given the results of a scope to maintain anonymity.
