Biomarkers in the Diagnosis and Assessment of Pulmonary Arterial Hypertension (PAH) (Biomarkers)

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT00566423
Recruitment Status : Completed
First Posted : December 3, 2007

Brief Summary:
The investigators hypothesize that baseline plasma brain natriuretic peptide (BNP) and migration inhibitory factor (MIF) levels are surrogate markers of clinical severity of PAH and that changes in plasma brain natriuretic peptide (BNP) and MIF levels pre and post exercise.

Condition or disease Intervention/treatment Phase
Pulmonary Arterial Hypertension Other: Blood draw Not Applicable

Detailed Description:
As above

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 75 participants
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Diagnostic
Official Title: Biomarkers in the Diagnosis and Assessment of PAH
Study Start Date : May 2007
Actual Primary Completion Date : May 2008
Actual Study Completion Date : June 2010

Arm Intervention/treatment
Experimental: 1
Patients with Pulmonary Arterial Hypertension
Other: Blood draw
Venous and Arterial Blood draw samples; 6 Minute Walk test

Primary Outcome Measures :
  1. Assess the correlation of plasma/arterial BNP and MIF levels pre/post with the 6 Minute walk test distance and echocardiographic parameters as surrogate markers of severity of PAH. [ Time Frame: 2 year ]

Secondary Outcome Measures :
  1. To determine if changes in plasma/arterial MIF levels pre/post 6MW test are due to MIF released from the lungs [ Time Frame: 2 year ]
