Pulmonary arterial hypertension (PAH) mainly affects the small pulmonary arterioles. It is a rare and progressive disease of the lungs. The right side of your heart is affected by this condition. In this disease, the blood vessels in your lungs get narrow or blocked. This damage results in blood flowing slowly through your lungs and your blood pressure in the arteries of the lungs rises. As a result, your heart muscle needs to work more in order to pump blood through your lungs. This puts extra pressure on the heart and it becomes weak.

 
PAH is evaluated based upon history, physical examination, exercise tolerance tests, functional assessment, and symptoms presented by the patients. There are some specific diagnostic tests that your doctor will recommend in order to diagnose PAH. The first indicator of PAH could be symptoms such as fatigue, syncope, shortness of breath, and dyspnoea. In some individuals, this can get worse and be life-threatening as well. Though there is no cure for PAH, treatment modalities can help reduce the symptoms and improve the quality of life of patients. 

Cure
There is no cure for PH, however, it can be prevented by following a healthy lifestyle to manage high blood pressure and avoiding the use of tobacco to prevent lung disease.
