A study designed to determine the levels of exercise-industry pulmonary hemorrhage in 2-year-olds racing in South Florida is complete, but the data won’t be released until a scientific paper is published after peer review.
The study, which involved 814 endoscopic examinations, was headed by Dr. Stephen Selway of the Gulfstream Equine Surgical Clinic. The information was gleaned from 2-year-olds that competed in maiden special weight races and stakes at Gulfstream Park in 2015.
Selway, in a Jan. 6 release, said the images were numbered, randomized, and evaluated by Drs. Jim Prendergast, Foster Northrop, and Nick Meittinis. He said the data, along with factors such as temperature, humidity, and barometric pressure “will be looked at statistically with regard to the EIPH and the variables in the study.”
“Until all images are graded and all of the data evaluated we cannot and will not make any conclusions as it is important to let the science speak,” Selway said. “One thing that is clear is that 2-year-olds do bleed, and in significant numbers. Also, we will be looking closely at one of the possible causes of EIPH to see if maybe a factor.
“Results of this timely scientific study will be of significant value regarding the health and welfare of the racehorse, EIPH, and its management.”
Selway said many owners and trainers agreed to participate in the study, as did Gulfstream management and the Florida Horsemen’s Benevolent and Protective Association. He also credited those who helped pick up costs or perform the imaging: Ahmed Zayat for laboratory costs; Caroline Wilson, John Sikura, Antony Beck, and Roy Jackson for video endoscopes; and veterinarians for assistance in collecting images.
Several other studies into EIPH, which is controlled by use of race-day furosemide, also called Lasix or Salix, are to begin this year or are underway. Under the National Uniform Medication Program Lasix is the only therapeutic medication permitted for use on race day.
