comparative evaluation of the evolution of emerging biological markers in patients hospitalized for acute heart failure according to conventional management or therapeutic adjustment via daily ultrasound.

Conditions: Heart Failure

Summary: this is a bi-centric, prospective randomized study to evaluate the contribution of rapid echocardioscopy at the patient's bedside to improving the prognosis of patients hospitalized for acute heart failure. the following markers will be evaluated: sst2, copeptin, chromogranin, ngal, supar and cystatin.

the jecica study is the first prospective randomized study to evaluate the contribution of rapid echocardioscopy at the patient's bedside to improving the prognosis of patients hospitalized for acute heart failure (paper submitted to the american heart journal, impact factor 4.15). the serum library set up to consider this ancillary study can now be used. with it, a comparative analysis of the expression profiles of emerging biological markers will be made according to whether patients received standard management or the "jet echo" strategy. the following markers will be evaluated: sst2, copeptin, chromogranin, ngal, supar and cystatin. this study should help to explain any differences in results observed, consider the development of multiparametric prognostic scores and explore the correlation between biological markers and the evaluation of echocardiographic congestion from a pathophysiological viewpoint. the results obtained should lead us to improve our usual practices for the management of heart failure patients.
