Pulmonary artery pressures in normal horses and in horses affected with chronic obstructive pulmonary disease

Equine Vet J. 1978 Jul;10(3):195-8. doi: 10.1111/j.2042-3306.1978.tb02260.x.


Horses clinically affected with chronic obstructive pulmonary disease (COPD) were found to have pulmonary artery hypertension which was associated with systemic arterial hypoxia. The pulmonary hypertension in symptomatic COPD-affected horses was partially reversible upon remission of clinical signs or by oxygen administration. The induction of acute hypoxaemia caused an increase in pulmonary artery pressure in both normal and COPD-affected horses.
