How do lung diseases affect the blood vessels?

ANSWER

The right side of the heart receives low-oxygen blood from the veins. It pumps blood into the lungs through the pulmonary arteries. These blood vessels can suffer from disease:

  • Pulmonary embolism: A blood clot (usually in a deep leg vein, deep vein thrombosis) breaks off, travels to the heart, and is pumped into the lungs. The clot lodges in a pulmonary artery, often causing shortness of breath and low blood oxygen levels.
  • Pulmonary hypertension: Various conditions can lead to high blood pressure in the pulmonary arteries. That can make you short of breath and have chest pain. When no cause is found, the condition is called idiopathic pulmonary arterial hypertension.
