Pulmonary artery diseases affect the blood vessels responsible for carrying oxygen-poor blood from the heart to the lungs. In this comprehensive guide, we will explore various aspects of pulmonary artery diseases in simple and clear language to enhance understanding.

Types of Pulmonary Artery Diseases:

  1. Pulmonary Arterial Hypertension (PAH):
    • Definition: High blood pressure in the pulmonary arteries, making it harder for the heart to pump blood to the lungs.
    • Description: The arteries narrow, putting strain on the heart and limiting oxygen flow to the body.
  2. Pulmonary Embolism:
    • Definition: Blockage in the pulmonary arteries, usually caused by blood clots traveling from the legs.
    • Description: This can be life-threatening, affecting blood circulation and oxygenation.
