Pulmonary hypertension (PH) is a type of high blood pressure that affects the arteries in the lungs and the right side of your heart.
The condition begins when tiny blood vessels in your lungs, called pulmonary arteries, and capillaries become narrowed, blocked or destroyed. These smaller arterial blood vessels may be abnormally thick, scarred, inflamed, constricted or have clots.
When this occurs, it inhibits blood flow through your lungs, and raises pressure within your lungs' arteries. This often leads to insufficient oxygen delivery and results in an excess load to the heart leading to “right sided heart failure.”
As the pressure builds, your heart's lower right chamber (right ventricle) must work harder to pump blood through your lungs, eventually causing your heart muscle to weaken and perhaps eventually fail.
Normally, the lung vasculature can easily adapt to exercise-induced marked increases in blood flow. However in pulmonary hypertension, the vascular resistance and the pressure in the lungs is further elevated with activity and leads to decreased flow to the left side of the heart (which pumps to the rest of the body).
Pulmonary hypertension should not be confused with hypertension — sometimes called systemic hypertension or high blood pressure. PH can occur in patients with or without this more common condition. The signs and symptoms of pulmonary hypertension in its early stages may not be noticeable for months or even years. As the disease progresses, however, symptoms worsen.
- Shortness of breath (dyspnea), initially while exercising and eventually while at rest
- Dizziness or fainting spells (syncope)
- Chest pressure or pain
- Swelling (edema) in your ankles, legs and eventually in your abdomen (ascites)
- Bluish color to your lips and skin (cyanosis)
