Occurrence of exercise-induced pulmonary haemorrhage in show jumping horses

摘要

Pulmonary haemorrhage occurs in sport horses performing high-intensity exercise, but the factors involved in the occurrence of pulmonary haemorrhage in jumping horses have not been elucidated. This study aimed to determine the occurrence of pulmonary haemorrhage and factors involved in competitive jumping horses. Fifty adult jumping horses competing in the city of Sao Paulo, Brazil, were included. The horses were divided into two groups based on jump height at competition: Low group (LG, n = 26), with jump height between 1.00 and 1.20 m, and High group (HG, n = 24), with jump height between 1.30 and 1.50 m. Physical examination was performed before and after competition, and airway endoscopy and tracheal wash (TW) were performed 1 h after competition.
