What is it?

Pulmonary vascular disease encompasses the various conditions that affect the blood vessels along the route between the heart and the lungs.  The process is, blood is pumped out of the heart, is delivered to the lungs to exchange carbon dioxide for oxygen which is used to oxygenate the whole body. If an aspect of this process is damaged, blocked or obstructed it can lead to a type of pulmonary vascular disease.  The various different types of pulmonary vascular disease are as follows;

  • Pulmonary venous hypertension: increased blood pressure in the pulmonary veins
  • Pulmonary embolism: a blood clot breaks off from a deep vein
  • Chronic thromboembolic disease: a blood clot in the lungs
  • Pulmonary arterial hypertension: increased blood pressure in the pulmonary arteries

What causes it?

  • Congestive heart failure
  • Damaged mitral valve in the heart
  • Lung disease
  • Autoimmune disease
  • Breakage of a blood clot in the veins or arteries
  • Blood clot failing to get reabsorbed by the body
