Pulmonary Hypertension

Pulmonary hypertension is elevated blood pressure in the pulmonary arteries (lungs), causing the right side of the heart to work harder and eventually fail.

Key Facts

  • Causes: heartworm disease, chronic lung disease, left-sided congestive-heart-failure, blood clots
  • Signs: exercise intolerance, syncope (fainting), cough, dyspnea, abdominal distension
  • Diagnosis: echocardiogram (Doppler estimation of pulmonary pressure)
  • Treatment: sildenafil (Viagra) is the primary medication; treats the symptom, not the cause
  • Underlying cause must be identified and treated
  • Species: dogs and cats
