Key result
Exercise-induced pulmonary hemorrhage and chronic obstructive pulmonary disease adversely affected racing performance in Standardbred racehorses, with the combination being more severe than either alone.

Does exercise-induced pulmonary hemorrhage or chronic obstructive pulmonary disease affect racing performance in Standardbred racehorses?
Exercise-induced pulmonary hemorrhage and chronic obstructive pulmonary disease, particularly in combination, are associated with poor racing performance in Standardbred horses.
Respiratory conditions merit evaluation in underperforming Standardbreds; leaves open whether treatment improves racing outcomes.
Endoscopic examinations were performed on 965 Standardbred racehorses competing at Yonkers Raceway between June 16 and Aug 3, 1988, to demonstrate an association between exercise-induced pulmonary hemorrhage or chronic obstructive pulmonary disease and poor racing performance. Findings suggested that both exercise-induced pulmonary hemorrhage and chronic obstructive pulmonary disease adversely affect performance, whereas a combination of the 2 conditions more severely affects racing performance than do either of the conditions individually.

MacNamara et al. (1990) conducted an observational in Exercise-induced pulmonary hemorrhage and chronic obstructive pulmonary disease (n=965). Exercise-induced pulmonary hemorrhage and chronic obstructive pulmonary disease vs. Absence of these conditions was evaluated on Poor racing performance. Exercise-induced pulmonary hemorrhage and chronic obstructive pulmonary disease adversely affected racing performance in Standardbred racehorses, with the combination being more severe than either alone.
