Up to 80% all racehorses will have blood in their trachea after strenuous exercise. Epistaxis is relatively rare, seen in only 1% horses after racing. However, if scoped the majority of horses will show bleeding from the lungs, evidenced as blood within the trachea after racing. Exact aetiology unknown, impact forces of the hooves striking the ground is thought to play a role.
