The debilitating respiratory syndrome often known as heaves or recurrent airway obstruction (RAO) is a common but serious problem for those who own and manage horses. Horses that live in barns, stables or outdoors—essentially all domesticated horses—are typically exposed to high levels of pollens, molds and other particulates, which puts them at an increased risk of developing this condition.
These terms fall under the umbrella of “equine asthma,” a performance-limiting, respiratory disease that affects horses with long-term exposure or excessive sensitivity to particulates. This is distinguished from the less severe form of equine asthma, known as Inflammatory Airway Disease (IAD), a much more common and potentially curable malady.1Conversely, RAO can often be effectively treated, but is not said to be curable.
The chief clinical sign distinguishing RAO from IAD is clearly recognizable episodes of respiratory distress. Here, a horse will appear to be struggling with the effort to breathe; these episodes are usually transitory until the horse becomes severely affected.
The most common clinical signs of RAO are:
- Chronic cough
- Nasal discharge
- Exercise intolerance
- Respiratory difficulty
Horses with RAO often appear normal at rest, but can have an increased respiratory rate and/or cough. When coughing is the prevalent symptom, a “heave line” will frequently be seen along the bottom edge of the ribs, caused by abdominal muscles which enlarge due to the excess work associated with breathing.
Forms of Recurrent Airway Obstruction
There are two forms of RAO. The first is the type associated with stalled horses; the second is summer pasture-associated recurrent airway obstruction (SPARAO).1 The latter is most commonly seen in horses that live on pasture and come in contact with high levels of airborne mold spores. Winter is usually the most common season for heightened symptoms of barn-associated RAO in the northern U.S., while the most prevalent signs of pasture-associated heaves happen in the Spring and early Winter in the north, and in summer and early fall in the south.
