It was a rough day at Pimlico beyond the rain and muddy track.

In a tragic start to Preakness day, (click here) two horses died after racing at Pimlico Race Course in Baltimore.

Homeboykris had rallied to win the day's first race by a half-length on a rainy Saturday. After having his picture taken in the winner's circle, he collapsed and died on his walk back to the barn. Track officials believe the 9-year-old gelding suffered cardiovascular collapse....
Of 235 Thoroughbred racehorses examined with a flexible fiberoptic endoscope within 2 hours of racing to determine the frequency of exercise-induced pulmonary hemorrhage (EIPH), 103 (43.8%) had various degrees of hemorrhage in the tracheal lumen. Two of these horses (0.8%) subsequently had blood flow from the nostrils. Blood seemed to originate from the lung. Statistical analysis of frequency data for 191 horses which finished in 1st, 2nd, and 3rd places did not show any relationship between EIPH and horse's age, sex, or finishing position. However, a trend toward an increased frequency of EIPH with age was shown, by a greater proportion of horses 5 years and older having EIPH. This trend is thought to reflect the chronicity of the pulmonary lesions and an inability of the lung to repair damaged regions while training and racing continued. The efficacy of furosemidefor the treatment of EIPH was questioned, since 30 of 56 furosemide-treated horses which were examined had evidence of pulmonary hemorrhage. Nineteen (8%) horses had visible functional abnormalities of the upper respiratory tract.

...In 2005, Tobin said, Kenneth W. Hinchcliff, BVSc, PhD, Dipl. ACVIM, (click here) a professor at the Faculty of Veterinary Science at the University of Melbourne, Australia, described an EIPH scoring system that is currently used:
  • Grade 0: No blood detected in the pharynx, larynx, trachea, or mainstem bronchi.
  • Grade 1: One or more flecks of blood, or two or fewer short (less than one quarter the length of the trachea) and narrow (less than 10% of the tracheal surface area) streams of blood in the trachea or mainstem bronchi present.
  • Grade 2: One long stream of blood (more than one-half the length of the trachea) or more than two short streams of blood occupying less than one-third of the tracheal circumference.
  • Grade 3: Multiple, distinct streams of blood, covering more than one-third of the tracheal circumference, with no blood pooling at the thoracic inlet.
  • Grade 4: Multiple, coalescing streams of blood covering more than 90% of the tracheal surface with blood pooling at the thoracic inlet.
"If you want to quantify the amount (or severity) of bleeding, you can do it visually," Tobin confirmed....
