The most important facts at a glance
Pulmonary hypertension in dogs is a condition in which blood pressure is elevated in the arteries between the heart and lungs. This can be caused by narrowing or blockages in these arteries, which force the heart to work harder to pump blood through the lungs. Common causes include chronicChronic refers to a condition or disease that is long-lasting or permanent. Chronic diseases often develop slowly and can lead to persistent or recurring health problems over time. lung diseases triggered by infections, inflammatory conditions, or allergies, as well as heart diseases that often cause a backflow of blood into the lungs. Thromboembolic diseases, in which blood clots block the pulmonaryPulmonary refers to the lungs or the respiratory system. Pulmonary diseases in dogs and cats include conditions such as Pneumonia, asthma, and pulmonary hypertension. arteries, can also play a role.
Symptoms include congestive heart failure, reduced resilience, respiratoryRespiratory refers to breathing or the process of breathing. Respiratory diseases affect the respiratory tract and can impair the ability to breathe effectively. distress, and sometimes bluish mucous membranes. Cough and weight loss are also common, while brief losses of consciousness are less frequent. DiagnosisA diagnosis is the identification of a disease or condition by its symptoms and/or results from diagnostic tests. It is the first step in the management and treatment of patients. requires a thorough clinical examination, often supported by echocardiographyEchocardiography is an ultrasound examination of the heart that assesses the structure and function of the heart valves and chambers. It can provide information about heart size, pumping function, and the presence of heart disease., X-rays, and blood tests. In some cases, cardiac catheterization may be necessary to measure blood pressure directly.
Treatment aims to alleviate the symptoms and treat the causes. Medications such as phosphodiesterase inhibitors and diureticsDiuretics are medications that increase urine production in the kidneys to rid the body of excess salt and water. They are often used to treat high blood pressure, heart failure, and certain types of edema. are often used to lower blood pressure and support heart function.

Preventive measures focus on treating heart and lung diseases, as well as a healthy lifestyle with regular exercise and a balanced diet.
Causes
Pulmonary hypertension occurs when blood pressure increases in the arteries that connect the heart to the lungs. This can be caused by a narrowing or blockage of these arteries, which impedes blood flow and forces the heart to work harder to pump blood through the lungs.

One of the most common causes is chronicChronic refers to a condition or disease that is long-lasting or permanent. Chronic diseases often develop slowly and can lead to persistent or recurring health problems over time. lung disease, which leads to decreased oxygen uptake. This can be triggered by infections, inflammatory conditions, or allergies.
Heart diseases, especially diseases of the left ventricleA ventricle is one of the two lower chambers of the heart that pump blood into the arteries. The right ventricle pumps blood to the lungs, while the left ventricle pumps blood throughout the body., can also lead to pulmonaryPulmonary refers to the lungs or the respiratory system.

In veterinary medicine, stress can have physical or psychological effects on animals, impacting their health and well-being..
Cough, especially a dry, persistentPersistent means lasting or continuing for an extended period. In veterinary medicine, it can refer to chronic diseases or symptoms that do not subside. cough, can also be a sign of pulmonaryPulmonary refers to the lungs or the respiratory system. Pulmonary diseases in dogs and cats include conditions such as Pneumonia, asthma, and pulmonary hypertension. hypertensionHypertension, or high blood pressure, is a condition in which the blood pressure in the arteries is consistently elevated. In dogs and cats, this can lead to damage to organs such as the heart, kidneys, and eyes, and requires medical treatment.. Dogs with this condition often show reduced resilience and are more easily exhausted than usual.
Another symptom may be blue or pale gums, which indicates a lack of oxygen in the blood. In advanced cases, fainting or collapse may occur, especially when the dog is excited or active.

Early detection and treatment of heart and lung diseases can help reduce the risk.
A healthy lifestyle, including regular exercise and a balanced diet, can also help reduce the risk of cardiovascular disease.
Regular veterinary examinations are important to detect signs of heart or lung disease early. Proactive monitoring and care can help maintain the dog’s health in the long term.
