NCT00384540

Last verified: February 2014
  Purpose

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.

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
