Brief Summary:

Pulmonary arterial hypertension (PAH) is a progressive disease that results in severe activity limitation and death. There are few treatments for PAH and the available medications are expensive, difficult to administer and have significant toxicities.

(-)-Epicatechin is a non-toxic compound that naturally occurs in foods such as tea, wine and chocolate. Clinical intervention studies using dark chocolate in normal volunteers and subjects at risk for or with established cardiovascular disease have demonstrated improvements in peripheral and coronary vascular endothelial function, blood pressure, lipids, glucose tolerance and inflammatory markers.

Our study intends to examine the hemodynamics effects of purified (-)-epicatechin in subjects with pulmonary arterial hypertension. We hypothesize purified (-)-epicatechin will reduce pulmonary vascular resistance in patients with pulmonary arterial hypertension.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 0 participants
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: An Open Label Pilot Study of Purified (-)-Epicatechin to Improve Hemodynamics in Pulmonary Arterial Hypertension
Study Start Date : July 2013
Estimated Primary Completion Date : January 2014
Estimated Study Completion Date : January 2014

Arm Intervention/treatment
Experimental: (-)-Epicatechin
A single dose of 100mg or 200mg (-)-Epicatechin to be administered orally
Drug: (-)-Epicatechin
A single dose of purified (-)-epicatechin will be administered orally to subjects after a regularly scheduled right heart catheterization. The subjects will be monitored for 5 hours and released.

Primary Outcome Measures :
  1. Pulmonary Vascular Resistance Index [ Time Frame: up to 5 hours after right heart catheterization ]
    This study will assess acute hemodynamic effects, specifically effects on pulmonary vascular resistance index (PVRI), of a single dose of purified (-)-epicatechin in patients with patients with PAH.

Secondary Outcome Measures :
  1. Endothelial function and hemodynamics [ Time Frame: up to 5 hours after right heart catheterization ]
    Secondary objectives are to determine if endothelial function, right heart function, nitric oxide and mitochondrial function improve following consumption of purified (-)-epicatechin.
