Pulmonary Arterial Hypertension
Welcome to PAH-info.com

Pulmonary arterial hypertension (PAH) is a serious disease of the arteries connecting the lungs to the heart (the pulmonary arteries).  As Pulmonary Arterial Hypertension (PAH) develops, blood flow through the pulmonary arteries is restricted and the right side of the heart is put under increasing strain to pump blood through to the lungs. This leads to the main symptoms of Pulmonary Arterial Hypertension (PAH) - breathlessness, chest tightness, limited exercise capacity and fatigue.

Untreated, Pulmonary Arterial Hypertension (PAH) is a disease with a very poor prognosis.

The early symptoms of Pulmonary Arterial Hypertension (PAH) - such as breathlessness, chest tightness and fatigue - can be mild and are common to many other conditions.  Reaching the diagnosis can be delayed and as a consequence patients with Pulmonary Arterial Hypertension (PAH) may first present when the disease has already progressed beyond a mild stage.  This website explains how Pulmonary Arterial Hypertension (PAH) develops, describes the symptoms associated with this disease and outlines how it can be diagnosed and treated.

Treatment is aimed at improving symptoms, exercise tolerance, long term outcomes and quality of life. Until the mid 1980s there were limited treatment options for patients and Pulmonary Arterial Hypertension (PAH) was associated with poor prognosis. Today, treatment options have improved the outlook for patients with this condition.
