Can heart disease cause PH?


Yes, in many patients, PH can be due to a disease of the heart.

In some types of heart disease, blood backs up into the lungs, causing PH:

  • Heart failure, due to previous heart attacks, high blood pressure (also known as systemic hypertension), or diabetes
  • Diseases of the valves of the left-side of the heart, specifically the mitral valve and aortic valve

Another important type of heart disease is due to defects of the heart present at birth (also known as congenital heart disease), such as:

  • atrial septal defect (ASD)
  • ventricular septal defect (VSD)
