Exercise-induced pulmonary hemorrhage (EIPH) and asthma in barrel racing horses is a common disease across the United States. Limited information is available on non-infectious respiratory diseases in this population, the interaction between these two diseases, and the occurrence of both EIPH and asthma in the horse. The purpose of this study was to evaluate the bronchoalveolar lavage (BAL) fluid cytological results of barrel racing horses with EIPH, asthma, or both. A retrospective study was conducted using the medical records of horses that presented with cough and decreased athletic performance and BAL results that met the criteria for inclusion. Data from 95 horses were included from a private practice referral hospital in Texas. No statistical difference was found in the frequency of neutrophilia, eosinophilia, or mastocytosis between diagnoses of EIPH, asthma, or concurrent diagnoses of EIPH and asthma. Bronchoalveolar lavage of horses suspected of EIPH is warranted to fully characterize the noninfectious respiratory disease of barrel racing horses.

运动引起的肺出血（EIPH）和滚桶赛马哮喘是全美国的常见疾病。关于该人群中非感染性呼吸系统疾病，这两种疾病之间的相互作用以及马中EIPH和哮喘的发生的信息有限。这项研究的目的是评估患有EIPH，哮喘或二者兼有的竞速赛马的支气管肺泡灌洗（BAL）液细胞学结果。进行回顾性研究，使用出现咳嗽和运动能力下降的马的医疗记录，以及符合纳入标准的BAL结果。来自95匹马的数据来自得克萨斯州的一家私人转诊医院。中性粒细胞，嗜酸性粒细胞增多，诊断为EIPH，哮喘或同时诊断EIPH和哮喘之间存在肥大细胞或肥大细胞增多症。怀疑是EIPH的马匹的支气管肺泡灌洗被认为能充分表征桶装赛马的非感染性呼吸系统疾病。
