Pulmonary Hypertension



Pulmonary hypertension (PH) is a a type of high blood pressure that affects the arteries in the lungs and the right side of our heart. It is a kind of extremely severe and risk disease. And the 75% of patients is in 20 ~ 40 years of age.

The PH begins when the tiny arteries in our lungs calledpulmonary arteries, and capillaries become narrowed, blocked or destroyed. This makes it harder for blood to flow through the lungs, and raises pressure within our lungs'arteries. As the pressure builds, our heart's lower right chamber (right ventricle) must work harder to pump blood through the lungs, eventually causing the heart muscle to weaken and cannot do its job, eventually can develop heart failure.

There are many reasons can lead PH, like left-sided heart failure, congenital heart disease, Anoxic lesions, pulmonary thromboembolism, ect,The most topic we talked about before is the COPD, it causes the Anoxic lesions for lung and can cause the PH too. 

According to the report, these specific causes of pulmonary hypertension occupied the main body of the crowd, can even reach 99%. 

The symptoms of PH include 

●  Shortness of breath during routine activity, such as climbing two flights of stairs 

●  Fatigue 

●  Chest pressure or pain 

●  A racing heartbeat 

●  Pain on the upper right side of the abdomen 

●  Decreased appetite 

●  Chest pressure or pain 

The pulmonary hypertension is devided into two kinds.One is Idiopathic pulmonary hypertension,when an underlying cause for high blood pressure in the lungs can't be found, the condition is called idiopathic pulmonary hypertension (IPH).Some are caused by genes, some are with unknow reason yet. And the other one is secondary pulmonary hypertension.The reasons we refered on above, they all belong to this kind. It is more common for the pulmonary hypertension.

Many doctors hold the idea it is a uncurable disease, but it is too old thinking. Though there are no effective ways to treat it at present, the new treatment like gene therapy/ lung transplant/ Interatrial septum colostomy have been in application.
