ClinicalTrials.gov Identifier:	NCT00566423

Purpose

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.

Further study details as provided by North Shore Long Island Jewish Health System:

Primary Outcome Measures:

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 ] [ Designated as safety issue: No ]

Secondary Outcome Measures:

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 ] [ Designated as safety issue: No ]

Estimated Enrollment:	75
Study Start Date:	May 2007
Estimated Study Completion Date:	June 2009
Estimated Primary Completion Date:	May 2008 (Final data collection date for primary outcome measure)
