When cure is care: diagnosis and management of pulmonary arterial hypertension.

Purpose: The purpose of this article is to provide nurse practitioners with an understanding of the pathophysiology of pulmonary arterial hypertension (PAH) disease, clinical manifestations, diagnostic evaluation, drug therapy, strategies for health promotion, and relevant care issues for patients and families.

Data sources: Selected clinical and research articles, as well as current government guidelines.

Conclusions: Symptoms expressed are more apparent as PAH disease progresses, leaving fewer treatment options in advanced disease stages. New drugs are currently being tested for the treatment of PAH; however, the costs of many of the currently approved treatments may be prohibitive.

Implications for practice: Earlier recognition of disease symptoms leads to prompt initiation of diagnostic evaluation and referral to specializing medical centers. Upon referral, specialty centers may begin appropriate treatment regimens earlier in the disease process, which could improve clinical outcomes and quality of life.
