Pulmonary Hypertension

Issue Description

Is an increase in blood pressure in the pulmonary artery, pulmonary vein, or pulmonary capillaries, together known as the lung vasculature, leading to shortness of breath, dizziness, fainting, and other symptoms, all of which are exacerbated by exertion. Pulmonary hypertension can be a severe disease with a markedly decreased exercise tolerance and heart failure.


The most common symptoms of Pulmonary Hypertension include shortness of breath, hyperventilation, fatigue, weakness which progresses, fainting, dizziness, coughing up blood.


Possible causes include increased blood viscosity (eg, polycythemia), increased pulmonary blood flow (eg, ventricular septal defect, patent ductus arteriosus, or atrial septal defect), and decreased overall cross-sectional area of the pulmonary vascular bed (such as caused by pulmonary arterial wall hypertrophy with heartworm disease, stenosis of pulmonary artery branches, pulmonary thromboembolism, or pulmonary vasoconstriction). Primary pulmonary hypertension is rare in dogs. In cattle, the most common cause is hypoxia-induced pulmonary vasoconstriction caused by dwelling at high altitude (High-mountain Disease). Chronic ingestion of locoweed ( Oxytropis and Astragalus spp ), or chronic pulmonary disease caused by bronchopneumonia or lungworm infestation can also result in cor pulmonale (brisket disease).


Treatment is typically unrewarding and the prognosis is poor. The best chance for a successful outcome is when the underlying disease can be identified and treated.

The American Society for the Prevention of Cruelty to Animals® (ASPCA®) was the first humane society to be established in North America and is, today, one of the largest in the world.

Our organization was founded on the belief that animals are entitled to kind and respectful treatment at the hands of humans and must be protected under the law. Headquartered in New York City, the ASPCA maintains a strong local presence, and with programs that extend our anti-cruelty mission across the country, we are recognized as a national animal welfare organization. We are a privately funded 501(c)(3) not-for-profit corporation, and are proud to boast more than 2 million supporters across the country.

The ASPCA’s mission, as stated by founder Henry Bergh in 1866, is “to provide effective means for the prevention of cruelty to animals throughout the United States.”

Jeff Gold, Founder, Rescue Me! Animal Rescue Network

Jeff Gold lives in Watkinsville, Georgia on the same property as Rescue Me's Animal Rehabilitation Center, with 18 rescue animals. Shown with him in the photo to the left are Maggie, Izzie and Cortez. In 2003, after learning there was nobody doing boxer rescue work in Georgia, Gold founded Boxertown, an organization which helped find homes for over 500 boxers during its first two years. Based upon this success, Gold came up with the vision for Rescue Me! ― a network which helps all breeds of dogs, cats and other animals find good homes, anywhere in the world. is also a free service of Rescue Me! and provides the world's largest and most up-to-date directory of animal rescue organizations for all breeds of dogs, cats and other animals, including a comprehensive directory of wildlife rehabilitators in over 150 countries.
