EXERCISE-INDUCED PULMONARY HEMORRHAGE - A REVIEW OF THE ETIOLOGY AND PATHOGENESIS

This paper reviews recent progress in the etiology and pathology of ex ercise-induced pulmonary hemorrhage (EIPH), a condition which poses an important cause of financial loss to the equine industry. It is hypot hesized that all horses experience some grade of EIPH during strenuous exercise. In light of the inflammatory response in lung tissue follow ing infusion of autologous blood and the chronic nature of EIPH in rac ing horses, every effort should be made to eliminate EIPH during exerc ise and to ameliorate the inflammatory response once hemorrhage has oc curred.
