Primary Pulmonary Hypertension is a rare disease characterized by the narrowing of blood vessels in the lungs causing difficulty to breathe and pressure on the lungs, which may lead to heart failure.

This disease is more common among women between the age 21 and 40 but can affect anyone.

The symptoms of PPH are shortness of breath, chest pains, dizziness and fainting. It is hard to detect this disease and easy to confuse it with several other heart or lung conditions, which is why it has often been misdiagnosed. It is recommended to see the doctor whenever these symptoms appear.

Possible causes of this disease are thought to be family history of PPH, some immune system or liver disease and drugs also exposure to some chemicals may trigger the development of this disease.

The PPH is rarely cured but various medications are used to relieve its symptoms. In case of some patients heart or lung transplantation may be necessary. Usually the median survival period after being diagnosed with PPH is 3 years but it is known that the period is significantly longer in case of people over 40 and people who don't have heart failure.
