Bleeders - EIPH

Post-race “bleeding” (exercise induced pulmonary hemorrhage, or EIPH), affects the vast majority of Thoroughbred and Standardbred racehorses. In addition, EIPH frequently occurs in hunter-jumpers and other horses performing intense exercise in events, steeplechases, and polo. It is commonly believed by jockeys, drivers, trainers, and owners that EIPH has a substantial negative affect on race performance.
