Pulmonary Hypertension

Pulmonary Arterial Hypertension (PAH)
Arizona Pulmonary  Pulmonary Hypertension TreatmentPulmonary Arterial Hypertension (PAH) is a progressive disease of the blood vessels of the lungs. Although it is not a common condition, increased awareness has led to an increase in diagnosis in the past decade. Like many diseases, it is asymptomatic in its earliest stages. With time, pressure inside the pulmonary arteries increases and blood flow through those vessels decreases. Eventually the right ventricle starts to fail, and fluid retention, marked fatigue and fainting episodes develop. Without treatment, most patients with PAH will not survive five years.

In the past 10 years, researchers have made tremendous progress in understanding the disease and developing effective treatments. There are many causes of PAH. There is a familial form of the disease that may be associated with connective tissue diseases such as scleroderma or lupus. Blood clots may causes PAH. The use of certain diet pills and stimulants such as methamphetamine also causes PAH. Congenital heart disease often leads to PAH. Patients with no identifiable cause are labeled as having Idiopathic PAH (IPAH).

The diagnosis of PAH requires a complex battery of tests including CT scans, echocardiograms, laboratory tests, six minute walk tests, breathing tests and a right heart catheterization. Patients with existing disease are followed with a carefully crafted protocol of testing.

Twenty years ago there no approved medications that effectively treated PAH. In 1995, Epoprostenol (Flolan) was approved. We currently have nine medications that are approved. Ongoing research will add to this number over the next five years. Although there is no cure for PAH, the prognosis has improved substantially. Lung transplantation remains an option for patients not responding to aggressive medical regimens.

PAH is a complex disease that requires dedicated expertise in diagnosis and management. Drs. Feldman and Ahearn are nationally recognized as experts in the diagnosis and management of pulmonary arterial hypertension. At Arizona Pulmonary Specialists we have built a comprehensive program specializing in the care of patients with PAH and other advanced lung diseases. We have two outstanding nurse coordinators to help manage our patients. In addition we have a very active research program that offers the latest experimental treatments for our patients.
