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.
Information provided by:
Northwell Health
  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.

Condition Intervention
Pulmonary Arterial Hypertension Other: Blood draw

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Diagnostic

Further study details as provided by Northwell Health:

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 ]

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 ]

Enrollment: 75
Study Start Date: May 2007
Study Completion Date: June 2010
Primary Completion Date: May 2008 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: 1
Patients with Pulmonary Arterial Hypertension
Other: Blood draw
Venous and Arterial Blood draw samples; 6 Minute Walk test
