  • The different projects

    Non-interventional protocols (medication is not administered):
    AmyloAFFECT: This questionnaire is meant to be taken during a check-up or a follow-up for heart failure. In this study, the answers from heart disease patients will be compared with those of cardiac amyloidosis patients. This aims to help doctors diagnose amyloidosis.
    This questionnaire is a self-assessment so it is up to the patient to fill it out. Questions focus on symptoms, when they first appeared and the patient’s medical history. It is a very general questionnaire. This information will help us to create a diagnostic scoring system so that it will be easier to differentiate between a standard heart condition and amyloidosis. We also think this will help us to become more familiar with the different types of amyloidosis.
    AmyloCOLLECT: This involves preserving blood samples which are administered with specific markers which will help us to better understand heart failure’s physiopathological mechanisms.
    Nutricoeur:
    The study aims to show that for patients with congestive heart failure, a program designed for dietary education, managing sodium intake and preventing malnutrition will be more effective than the usual dietary advice (which usually just focuses on sodium intake) that patients receive at unscheduled hospital visits six months after.
    The objectives are to:
    • Show that this new dietary education programme can improve nutrition, quality of life, practical application of dietary recommendations and the burden of being limited by a low-salt diet
    • Show how useful educational materials are in setting up the new education programme for preventing malnutrition (personalised meal plans and recipes)
    • Study the link between salt intake (prescribed and/or actual consumption) in a low-salt diet and morbimortality, the quality of life and the difficulties of being limited by a low-salt diet. This secondary objective is based on recent studies which suggest that a strict low-salt diet could be damaging (in terms of morbimortality and moderately reduced salt-intake).
    • To study the link between salt intake (prescribed and actually consumed) and energy and protein intake. The hypothesis underpinning this objective is that the stricter the low-salt diet, the weaker the balanced diet becomes if protein and energy intake are insufficient.
    Inclusion criteria:
    • Chronic heart failure
    • Cardiac decompensation in the last two years
    Safe Home:
    This aims to show how safe and efficient home hospital visits are in comparison to standard hospitalisation for patients with chronic decompensated heart failure.
              Inclusion criteria:
    • Recurrent hospitalisation for cardiac decompensation
    • Right-sided heart failure requiring IV diuretics
    • Hospital home care within a maximum of four days after hospitalisation
    • To diagnose patients in the 48h hospitalisation period
    Exclusion criteria:
    Undetermined heart failure
    AMYLO-CARTESIAN: This aims to evaluate the impact (morbidity and mortality) of cardiac transthyretin amyloid deposits (CA) and/or cardiac retention of diphosphonates in scintigraphs in elderly patients with aortic stenosis who have had a valve replacement.
    The objectives are to:
    • Determine and compare the sensitivity and specificity of echocardiographs and MRIs when diagnosing cardiac amyloidosis.
    • Determine how prevalent wild type transthyretin cardiac amyloids are in patients with calcific aortic stenosis who have had an aortic valve replacement.
    • Start a bio-bank of blood samples and identify the biomarkers of wild type transthyretin cardiac amyloids, a sign that calcific aortic stenosis surgery or TAVI is needed.
    Inclusion criteria:
    • Severe calcific aortic stenosis
    • Patient age ≥70
    • Ejection fraction ˂60% or strain rate ˃ -17%
    Exclusion criteria:
    • Other serious illnesses
    • Illness which requires mitral valve surgery
    • Aortic insufficiency (class ˃III)
    AMYLODEAFNESS: This study involves a hearing screening. Amyloid deposits can infiltrate different anatomical structures in the ear. Moreover, some diuretic treatments which are necessary to treat heart failure can sometimes cause hearing damage and cardiological problems can impair vascuralisation of the inner ear leading to decreased hearing. Having a better description of these anomalies could help diagnose patients with early-onset amyloidosis (particularly after a hearing check-up) and improve care for all patients with amyloidosis.
    Interventional protocols (involving the administration of medication)
    VICTORIA: This aims to evaluate how effectively Vericiguat, a stimulant taken orally consisting of soluble guanylate cyclase (sGC), can delay the first occurrence of the composite endpoints of death due to cardiovascular disease or hospitalisation due to heart failure in patients affected by heart failure with preserved ejection fraction receiving standard treatment, and this will be compared with a placebo.

    GALACTIC: This aims to evaluate how OMECAMTIV MECARBIL treatment affects time elapsed before death caused by cardiovascular problems or the first instance of heart failure (whichever comes first) in patients with chronic heart failure with reduced ejection fraction receiving standard treatment.
