What does PH do to my body?


 

The narrowing of the pulmonary arteries leads to the abnormally high blood pressure in the pulmonary arteries, which is called PH.

The narrowing of the pulmonary arteries means the right ventricle (RV = lower chamber on the right side) of the heart has to work harder to pump blood through the lungs. Because the RV of the heart has to work harder in PH, it is the RV that eventually gets weak, leading to RV failure, a type of heart failure. Heart failure means the heart cannot pump enough blood for the body’s needs. There is reduced blood flow to the organs of the body. Reduced blood flow causes the symptoms of difficulty breathing, fatigue, chest pain, and faintness.

If PH is not treated, the RV of the heart will eventually fail in many PH patients, which may lead to death.
