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.
