Cardiac Allograft Vasculopathy and Dobutamine Stress Echocardiography / Brain Natriuretic Peptide Coupling

This study has been completed.
Information provided by (Responsible Party):
University Hospital, Strasbourg, France Identifier:
First received: October 5, 2006
Last updated: August 16, 2017
Last verified: August 2017

Primary purpose :To early detect cardiac allograft vasculopathy and to identify patients with high risk of cardiac events, by coupling the analysis of the kinetics of the brain natriuretic peptide ( BNP) with that of the left ventricle (LV) during a dobutamine stress echocardiography.

Hypothesis : Plasma BNP elevation and abnormalities of LV kinetic during the ESD, will be associated with the presence of allograft vasculopathy and the arisen of cardiovascular events.

Condition Intervention
Vasculopathy Allograft Procedure: Dobutamine stress echocardiography, coronarography, brachial arterial echography

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: Single (Investigator)
Primary Purpose: Diagnostic
Official Title: Allograft Vasculopathy After Heart Transplantation : Diagnostic Interest of Dobutamine Stress Echocardiography and Brain Natriuretic Peptide Coupling

Enrollment: 53
Actual Study Start Date: September 2006
Study Completion Date: December 20, 2016
Primary Completion Date: November 22, 2015 (Final data collection date for primary outcome measure)
Intervention Details:
    Procedure: Dobutamine stress echocardiography, coronarography, brachial arterial echography
    DSE: cumulative doses of dobutamine (max = 40 µg/kg/min) and atropine (max = 1.5 mg), to reach a maximal heart rate under clinical, electrocardiographic and echocardiographic surveillancesCoronarography: invasive injection into coronary arteries of a radiological product showing a contrast visible on an x-ray. FMD: Flow-mediated dilatation of the brachial artery induced by 5-min forearm arterial occlusion
