Pulmonary hypertension in dog: Case report

The pulmonary hypertension in dogs is a progressive and serious disease, characterized by abnormal and persistent increase of pressure in pulmonary vasculature and pulmonary artery pressure (>25-30mmHg). Clinical signs of pulmonary hypertension are usually nonspecific and discrete, which leads to a delay in diagnosis. When signs are observed, they are related with the respiratory and cardiovascular tract, where the animal may present dyspnea, tachypnea, respiratory distress, syncope, cough and cyanosis. This case report describes a female dog with 12 year-old, Shih-Tzu breed that presented pulmonary hypertension associated with heart disease, infection and suspected of hyperadrenocorticism.
