Oral Water Ingestion in Heart Transplant Patients - Full Text View

Purpose

In this study the investigators propose to assess the hemodynamic response to the ingestion of 16 fl oz of water. The investigators will test the hypothesis that water ingestion will increase the systemic vascular resistance.

Secondary Outcome Measures:

blood pressure [ Time Frame: 40 min ] [ Designated as safety issue: No ]

Estimated Study Completion Date:	December 2008
Estimated Primary Completion Date:	December 2008 (Final data collection date for primary outcome measure)

Arms	Assigned Interventions
1: Experimental water ingestion	Dietary Supplement: water water 500 ml x 1

Detailed Description:

In this study we propose to assess the hemodynamic response to the ingestion of 16 fl oz of water. We will test the hypothesis that water ingestion will increase the systemic vascular resistance. This study will occur in patients status post cardiac transplantation during their clinical right heart catheterizations. Invasive hemodynamics including cardiac outputs and plasma norepinephrine levels will be measured before and 30 min after the water ingestion.
