Treatment of Heaves Subject of Penn Vet Lecture

On Tuesday, Oct. 1 at 6:30 p.m., Rose Nolen-Walston, DVM, Dipl. ACVIM, will present the lecture “Treating Heaves in Horses,” as part of the First Tuesday Lecture Series at the University of Pennsylvania's College of Veterinary Medicine (Penn Vet) New Bolton Center, 382 West Street Road, Kennett Square, Pa.

Nolen-Walston is an assistant professor of medicine in the Department of Clinical Studies at New Bolton Center, specializing in large-animal internal medicine. She will discuss New Bolton Center’s cutting-edge research on heaves and review the most current recommendations for treatment. Heaves is a chronic and often career-limiting lung disease seen in older horses.

The medical name for heaves is recurrent airway obstruction, or RAO. Horses with RAO are hypersensitive to inhaled triggers, usually hay and barn dust, and respond with difficulty breathing and reduced airflow. Although no permanent cure exists for RAO, changes in management as well as certain medications can reduce the symptoms to the point where many horses can engage in athletic pursuits and have an excellent quality of life.

During the First Tuesday Lecture Series, faculty and clinicians at New Bolton Center share current information on topics of interest and relevance to horse owners and caregivers throughout the region. Many of the lectures highlight the advanced techniques performed by Penn Vet’s team of leading clinicians and the state-of-the-art equipment and facilities available to ensure the best possible outcomes for patients.

The lectures are free and take place in New Bolton Center’s Alumni Hall. Due to limited seating, reservations are recommended and can be made by contacting Barbara Belt at
