Summary

The purpose of this study is to better understand the time course of different biological mechanisms involved in acute decompensated heart failure complicated by cardiogenic shock throughout the evaluation of changes and the relationship among markers of inflammation (IL-6) and markers of increased endothelial permeability (Ang-2) or endothelial glycocalyx perturbation (Syndecan-1 and HS) and throughout a targeted metabolomic approach.

Detailed description

Cardiogenic shock (CS) is a heterogenous syndrome with in-hospital mortality up to 60%, that, unfortunately, has remained stagnant over the time, despite observed improvements with pharmacological and non-pharmacological approach, even though only in terms of haemodynamic stabilization. While very early mortality in CS is largely related to sudden and severe circulation failure, subsequent death is strongly influenced by activation of neurohumoral and inflammatory response leading to multiorgan failure. Previous studies on CS have almost exclusively been focused on CS following an acute coronary syndrome (ACS). Patients with acutely decompensated heart failure (ADHF) represent a different pathophysiologic phenotype compared with acute coronary syndrome (ACS) patients, which may lead to a differential response to device therapy. In the face of complex biological phenomena guidelines are incapable of distinguishing the underlying pathophysiological mechanisms and give us input to standardize, whereas there is an unmet need for a personalized medicine. The evaluation of changes and the relationship among markers of inflammation (IL-6) and markers of increased endothelial permeability (Ang-2) or endothelial glycocalyx perturbation (Syndecan-1 and HS) and an exploratory analysis throughout targeted metabolomics may help us to better understand the time course of different biological mechanisms involved in CS.

Interventions

Type	Name	Description
DIAGNOSTIC_TEST	ELISA	Blood and derived fluids will be collected from 26 ADHF CS patients admitted to intensive care at Niguarda Hospital and locally stored.Stocked samples will be shipped to the Central Laboratories at Milano Uni and MilaIFC-CNR for the metabolomic and biomarkers analysis,respectively.To evaluate interleukin-6 (marker of systemic inflammation),angiopoietin-2 (marker of endothelial permeability), syndecan-1 and heparan sulfate (markers of endothelial glycocalyx),2 aliquotes of serum samples will be used by IFC CNR.The biomarkers will be assessed through ELISA analytical techniques, based on the interactions inside a microplate between a primary pre-coated antibody and the specific protein contained in serum samples.A secondary antibody, link to a horseradish peroxidase (HRP) detection system, is able to recognize and bind the antigen, and to produce a colorimetric reaction after the addition of enzyme substrate which is proportional to the amount of the target protein bound
