Online Presentation

Program Description

NOTE: This activity was presented on April 14, 2011, in conjunction with the International Society for Heart & Lung Transplantation's 31st Annual Meeting and Scientific Sessions. Participants who received credit for attending the live presentation on that date are not eligible to receive credit for this online release.

Pulmonary arterial hypertension (PAH) comprises a group of diseases characterized by vascular proliferation and a progressive increase in pulmonary vascular resistance that ultimately leads to right ventricular failure and early mortality. Three classes of drugs acting on different pathways related to vasodilation and vascular remodeling have been approved for the treatment of PAH in the last 15 years: prostanoids, endothelin receptor antagonists, and type 5 phosphodiesterase inhibitors. Over 320 clinical trials on the management of PAH are currently registered with the U.S. National Institutes of Health, promising that even newer therapies and guidelines for existing therapies are forthcoming. Clinicians, however, are struggling to integrate this wave of new research into effective evidence-based approaches to therapy.

In spite of the remarkable increase in available treatment options for PAH, their effect on the outcomes in PAH patients is not clear. The overall mortality rate associated with PAH did not change significantly between 1980 and 2002, although improved survival rates have been observed with some treatments. Prompt diagnosis and regular monitoring are important factors in patient outcomes.

This interactive presentation will challenge clinicians to take a more active role in the evaluation and management of PAH and to increase their knowledge of the latest available evidence. Improved education and awareness of recent findings and current recommendations can lead to substantial improvements in patient care.

Target Audience

This educational activity is designed to meet the needs of physicians who treat patients with pulmonary arterial hypertension (PAH).

Learning Objectives

Upon completion of this educational activity, the participant should be able to:

  1. Identify some of the major challenges associated with guideline-driven care for patients with PAH.
  2. Describe the evolution and role of prostanoids in the treatment of PAH.
  3. Discuss the evolving science behind the role of prostanoids on antiproliferative effects, endothelial dysfunction, and vascular remodeling.
  4. Evaluate the evidence for combination drug therapy in patients with PAH.
