Exercise Induced Pulmonary Hemorrhage

Exercise Induced Pulmonary Hemorrhage

Exercise Induced Pulmonary Hemorrhage (EIPH) also known as "bleeding" or a "bleeding attack" has been known to occur in horses that engage in short periods of strenuous exercise. These horses usually include Thoroughbred and American Quarter Horse racehorses (incidence of 50-75%) and Standardbred racehorses (incidence of 40-60%), but it may also occur in jumpers, polo ponies, and draft horses that pull competitively. Riegal, Ronald J. DMV, and Susan E. Hakola DMV. "Illustrated Atlas of Clinical Equine Anatomy and Common Disorders of the Horse Vol. II". Equistar Publication, Limited. Marysville, OH. Copyright 2000. ] It appears rarer in stallions than mares or geldings, [Hillidge CJ, Whitlock TW, (1986) "Sex variation in the prevalence of exercise-induced pulmonary haemorrhage in racing quarter horses" "Res Vet Sci." 1986 May;40(3):406-7] but it is associated with airway inflammation and increasing age. [Newton JR, Wood JL, (2002) "Evidence of an association between inflammatory airway disease and EIPH in young Thoroughbreds during training" " Equine Vet J Suppl." 2002 Sep;(34):417-24]

The affliction occurs when blood enters the air passages of a horse's lung, due to fractured lung capillaries. Blood is sometimes evident discharging from a horse's nostrils (epistaxis), however, this usually only occurs in 5% of bleeders.

It is believed that nearly all horses experience it (when exposed to strenuous exercise)AAEP Newsroom September 1999, at [http://www.aaep.org/press_room.php?id=42] , accessed at 1945 on 11th July] and it has the potential to decrease lung function over time.

Treatment

The drug commonly known as Lasix (Furosemide) has been used to prevent the condition, although it does not work in 50% of cases, and it is banned in some countries. Any racehorse in Australia that suffers from a bleeding attack during or following a race, or during trackwork exercise, receives an automatic 3-month ban from racing. A further occurrence results in a lifetime ban.

Other treatments that have been used include bronchodilators, coagulants, and estrogen.
