'''There are two types of pulmonary hypertension:'''  

1. '''Primary''' pulmonary hypertension=idiopathic pulmonary hypertension (Contributing factors: Drugs, Toxins, Genetic Predisposition and Infections)  

1. '''Primary''' pulmonary hypertension = idiopathic pulmonary hypertension (contributing factors: drugs, toxins, genetic predisposition and infections)  

2. Secondary pulmonary hypertension=pulmonary hypertension resulting from an identifiable underlying condition  

2. '''Secondary''' pulmonary hypertension = pulmonary hypertension resulting from an identifiable underlying condition  

[[Cor Pulmonale|'''cor pulmonale''']]=right sided heart failure resulting from pulmonary hypertension. Pulmonary thromboembolism from neoplasia, heart worm disease, and other factors can cause cor pulmonale by blocking the pulmonary vessels with emboli leading to increased pulmonary arterial pressures and ultimately right sided heart failure. The hypoxic conditions at high elevations or animals with chronic airway disease contribute to pulmonary hypertension through hypoxia-induced vasoconstriction.  

[[Cor Pulmonale|'''Cor pulmonale''']] = [[Heart Failure, Right-Sided|right sided heart failure]] resulting from pulmonary hypertension.  

Some diseases predispose animals to secondary pulmonary hypertension. Predisposed breeds include Brachycephalic Dogs (chronic obstructive pulmonary disease); Small breeds (mitral endocardiosis) and West Highland White Terriers (Pulmonary Fibrosis). <br>

The hypoxic conditions at high elevations or animals with chronic airway disease contribute to pulmonary hypertension through hypoxia-induced vasoconstriction.  

Clinical signs may vary and also may be disguised by other signs of the underlying, causative disease. There is often signs of right sided heart failure, such as exercise intolerance, dyspnoea, coughing, syncope, cyanosis, abdominal distension and distended jugular veins.

Physical Examation, depending on any underlying conditions, may show a heart murmur (Mitral or tricuspid regurgitation), presence of a gallop rhythm, increased lung sounds and splitting of S2 heart sounds.  

Physical examination, depending on any underlying conditions, may show a [[Heart Murmurs|heart murmur]] (mitral or tricuspid regurgitation), presence of a gallop rhythm, increased lung sounds and splitting of S2 heart sounds (see [[:Category:Arrhythmia|arrhythmias]]).  

Blood tests may show arterial blood gases (Hypoxemia): If there are low oxygen conditions. Complete Blood Count will show an eosinophilia if parasitic involvement. Serology or Fecal Baermann tests confirm parasitic involvement. Biochemistry would show hyperglobulinemia if chronic inflammation.

Blood tests:

:Arterial blood gases may show hypoxemia if there are low oxygen conditions.  

:Complete Blood Count will show an eosinophilia if ther is parasitic involvement. (Serology or Fecal Baermann tests would confirm parasitic involvement).  

:Biochemistry would show hyperglobulinemia in chronic inflammation.

Urinalysis may show the presence of proteinuria if systemic disease is present.
